„Professor Cai, your review. My student, uses the material of your school laboratory, the bi-color metal link that sintering has, what technical standards can reach?” “蔡教授,您点评一下。我的学生,利用贵校实验室的材料,烧结出的这枚双色金属环,能达到什么样的技术水平呢？” Ye Qing just went, sees one to wear blue western-styled clothes, on the face some middle-aged men in smallpox seal, is patting the slot machine to be the same, laughs is patting young student. 叶青刚一进去,就看见一名身着蓝西装,脸上有些痘印的中年男子,在拍老虎机一样,大笑着拍身旁的年轻学生。 In this student hand, the metal ring, attracted the Ye Qing's attention. 在这位学生手中,有一枚金属圆环,吸引了叶青的注意。 This is a lateral section is the metal ring of square shape, the size and ordinary bracelet size is equal. 这是一枚横截面为方形的金属圆环,尺寸和普通镯子尺寸相等。 In the metal link that powder metallurgy laboratory sintering has, naturally comes out with powder metallurgy technology processing. However this metal link, unexpectedly half of golden yellow, half of silver. 在粉末冶金实验室烧结出的金属环,自然是用粉末冶金技术加工出来。但是这个金属环,竟然一半金黄色,一半银色。 Most essential is two color intersection points, the trace of does not have any splicing and polish, is completely unified whole. 最关键是两种颜色的交汇处,没有任何拼接和打磨的痕迹,完全是浑然一体。 „Very...... fierce.” Zhongyun University leads, is Professor Cai Chenning. At this moment does not know is the temperature that the sintering furnace in room sends out is too high, is other what reason. On the Professor Cai Chenning forehead, has covered entirely the close beads of sweat in any case. “很……厉害。”中云大学这边带队地,是蔡晨宁教授。此刻也不知是房间里的烧结炉散发出的温度太高,还是其它什么原因。反正蔡晨宁教授的额头上,已经布满了细密的汗珠。 However Japan Technologies University, facial expressions are happy, the forehead does not see the beads of sweat. 不过日理工大学这边,一个个神情怡然,额头丝毫不见汗珠。 „That whether also to invite your school, demonstrated the powder metallurgy technology for us?” Professor Kobayashi Sei that Japan Technologies University leads, bends the waist to make an invitation posture: „Not necessarily takes two metal sintering in the same place, other also good, so long as is your school felt it is advanced.” “那能否也请贵校,为我们展示一下粉末冶金技术呢？”日理工大学带队的小林井教授,弯腰做出一个邀请姿势:“不一定非要两种金属烧结在一起,其它的也行,只要是贵校觉得它是先进的就可以。” Also defeat a game...... 又败下了一局…… The blue vein on Professor Cai Chenning forehead beats back and forth. 蔡晨宁教授额头上的青筋来回跳动。 From rank, without doubt Japan Technologies University compared with Zhongyun University many. However before Professor Cai Chenning, somewhat pure believing, this academic exchanges, are not the two countries most state-of-art National Grade industry laboratory technology competition. 从排名上来说,无疑日理工大学要比中云大学强了不少。但是蔡晨宁教授之前有些单纯的认为,这场学术交流,并不是两国最尖端的国家级工业实验室技术大赛。 Is University lives to University lives, even on the technological gap, not representative Zhongyun University, not with the thing that does not act, lets Japan Technologies this group of students open an eye opener. 都是大学生对大学生,就算就技术差距,也不代表中云大学,就没有拿不出手的东西,来让日理工这帮学生们开开眼。 However the fact result, making the Professor Cai Chenning heart probably jump. 然而事实结果,让蔡晨宁教授心脏都要蹦跳了出来。 Up to now, the size altogether came seven technologies to compete with, finally Zhongyun University only drew one game. 截至目前,大小一共来了七场技术比试,结果中云大学只扳回了一局。 Really, a game that in the morning they lose, looked in the afternoon. 果然,上午他们丢的一局,下午就找了回来。 In the afternoon visits the powder metallurgy laboratory, leading Professor Kobayashi Sei, lets in them impatiently a student of undistinguished appearance, the material in use laboratory, gives them the Mechanical Engineering Department students, took a class well. 下午来参观粉末冶金实验室,带队的小林井教授,就迫不及待地让他们中的一位其貌不扬学生,利用实验室内的材料,给他们机械工程系的学生们,好好上了一课。 Variation metal sintering. 异种金属烧结。 In the industrial processing domain, will often come across such a issue. 在工业加工领域中,往往会遇到这样的一个问题。 How two material quality different metal, to weld together? 如何把两种材质不同的金属,焊接在一起？ The slang said that different is not the stratagem, this saying puts in the metal welding industry also is also suitable. Different metal because of the difference of melting point and characteristics, weld forcefully, because definitely the welding place intensity will be too low, will fall toward the ground, „pā dā” will succeed in giving up two sections. 俗话说道不同不相为谋,这话搁金属焊接行业中也同样适用。不同金属因为熔点和特性的不同,强行进行焊接,肯定会因为焊接处强度太低,往地上一摔,“啪嗒”断成两截。 The welding of variation metal is quite difficult, not only needs very deep understanding of the metal material, can draw up various solder plans as circumstances permit, but must master the master welding technology, can weld the intensity qualified industry components. 异种金属的焊接极为困难,不仅需要对金属材料有着非常深厚的了解,能因地制宜地拿出各种焊剂方案,还要掌握宗师般的焊接技术,才能焊接出强度合格的工业零件。 Grasps the person of this technology, is the treasure that major Factory fight for mutually. 掌握这种技术的人,无不是各大工厂相互争抢的宝贝。 In powder metallurgy, variation metal sintering is Boss is also difficult. 在粉末冶金中,异种金属的烧结同样是老大难。 Because of the difference of metal melting point, needs in two metal agglutination places, increasing one layer can stuck two materials the bond. Then, wanting sintering to produce a qualified product, often must discard more than ten products. 因为金属熔点的不同,需要在两种金属的粘合处,添加一层能够黏住两种材料的粘合剂。就这样,想要烧结出一件合格的产品,往往都要报废十几件产品。 The innate insufficiency, was doomed variation metal welding, is variation metal sintering, can only be very young numerous very profound processing technology. 先天的不足,注定了无论是异种金属焊接,还是异种金属烧结,都只能是很小众很高深的加工技术。 But this afternoon, a Japan Technologies University graduate student, with silver and copper two powdered metal, without joining bond, successfully sintering leaves time may be called the perfect variation metal ring. 可是就在今天下午,日理工大学的一名研究生,用银和铜两种金属粉末,在不加入粘合剂的情况下,一次成功地烧结出堪称完美的异种金属圆环。 This product, is not the good to look at but of no use good-looking but useless goods. 偏偏这件产品,不是中看不中用的样子货。 That student to prove this, his work, has given Zhongyun University, has examined with the pulling force reflectoscope reflector. 那名学生为了证明这点,已经将他的作品,交给中云大学这边,用拉力测试仪检测过。 „Professor Kobayashi Sei, the weather early, I do not think that the student in your school was certainly hungry, tonight the cafeteria prepares the piece of skin roast duck for everyone specially, might as well make the students chat while eating?” Professor Cai Chenning had no alternative to hit the careless eye, acknowledged in disguised form Zhongyun University students, could not put out similar powder metallurgy technology. “小林井教授,天色已经不早,我想贵校的学生一定饿了吧,今晚食堂特意为大家准备了片皮烤鸭,不如让学生们边吃边聊？”蔡晨宁教授无可奈何地打起了马虎眼,也变相承认中云大学的学生们,拿不出类似的粉末冶金技术。 What Japan Technologies University sends out is a graduate student, then according to the rule of agreement established custom, Zhongyun University, can only send out the graduate student or University lives. 日理工大学派出的是一名研究生,那么按照约定成俗的规则,中云大学这边,只能派出研究生或大学生。 Professor Cai Chenning cannot go on stage personally. 蔡晨宁教授总不能自己亲自上场。 „Isn't hungry.” Kobayashi Sei lifted the head, in the look projected two self-satisfied rays: „Tanaka, you communicate with them, variation metal burn skill.” “不饿不饿。”小林井抬起了头,眼神中射出了两道得意光芒:“田中,你跟他们交流一下,异种金属的烧制技巧。” The student who that grasps the metal link, raised the head proudly, the vision observes the situation the audience: „Among different metal, the physical property difference is very big. A sintering technology that I use, is the base gradient attachment principle. First puts in the mold and prepressurization strength formation two powdered metal one by one, later with the electrothermal furnace sintering process , the request to the control temperature is harshest.” 那名手持金属环的学生,骄傲抬头,目光环视全场:“不同金属之间,物理性能差异很大。我使用的一次烧结技术,是基梯度接头原理。先将两种金属粉末逐一置于模具中并预加压力成型,随后采用电热炉烧结过程中,对控制温度的要求最为苛刻。” „Melting point 961 degrees of silver, melting point 1083 degrees of copper. How to find these two metal melting points the balance point knack, in two material powder, exerted pressure pressure different above. Because the crevice density between materials, decided the melted speed.” “银的熔点961度,铜的熔点1083度。如何找到这两种金属熔点的平衡点诀窍,在两种材料粉末,施压的压力不同之上。因为材料之间的空隙密度,决定了融化速度。” Zhongyun University here students, vision that avoids Tanaka. 中云大学这边的学生们,一个个避开田中的目光。 Defeated defeated, who made the technology be inferior to the person? 败了就败了吧,谁让技术不如人呢？ Is good because of this Tanaka student, not a taking the opportunity show wave of superiority feeling, otherwise they looked for the heart that a seam wormed one's way into to have. 好在这位田中学生,没有借机秀一波优越感,否则他们找个缝钻进去的心都有了。 The Tanaka person is good, not only spoke the technical point, has not attacked the person. 田中的人不错,不仅把技术要点讲出来了,还不打击人。 Was this group of students was too naive, Japan Technologies University travelled to distant lands to come, did not attack the person, wasn't that white to come? 是这帮学生太天真了,日理工大学远渡重洋而来,不打击人,那不是白来了？ „merely......” “只是……” „In operation, I discovered several issues.” “在操作中,我发现了几处问题。” This student named Tanaka, suddenly a thread of conversation revolution, the tone becomes proud: „Your device were too backward, in the laboratory in our school. Presses ramming machine tools that the embryo uses, is the Yamazaki Mazak Company multiple perspectives CNC punching machine.” 这位叫田中的学生,忽然话锋一转,语气变得骄傲起来:“你们的设备太落后了,在我们学校的实验室。压胚用的冲压机床,是山崎马扎克公司的多角度数控冲床。” „Your this device, angle not adjustable also on let it be, unexpectedly impact factor not adjustable.” “你们这台设备,角度不可调也就算了,竟然连冲击系数也不可调。” „Our school, piles abandonment device in Warehouse, compared with your advanced.” “我们学校,堆在仓库中的报废设备,也比你们这台先进。” „These powdered metal, we in the 1960s, on Yura two Professor, invented the micro metal particle fabrication technology.” Tanaka twisted on the finger residual powdered metal: „But you take this type thickly such as the thing of bread flour to use as before.” “还有这些金属粉末,我们早在上世纪六十年代,上田良二教授,就发明了超微金属纳米粒子制备技术。”田中捻了捻手指上残留的金属粉末:“可是你们依旧拿这种粗如面粉的东西用。” „The most essential electric heating sintering furnace, it our last century technical standards were even inferior. The laboratory must have the appearance of laboratory, with this elimination device, how can promote the progress of powder metallurgy technology?” “最关键的电热烧结炉,它甚至连我们上个世纪的技术水平都不如。实验室就要有实验室的样子,用这种淘汰设备,如何能推动粉末冶金技术的进步？”
