Study on Standardization of Wear Testing

本课题自1994年以来，结合日本机械工程师学会“磨损试验标准化”课题组的活动，对磨损试验标准化的可能性进行了研究。遗憾的是，JIS在研究开发过程中开发的新材料的磨损性能时，没有标准的金属材料磨损试验方法。我们讨论了磨损试验的标准化问题和试验方法的目的。由于磨损试验的要求多种多样，提出的标准磨损试验方法并不能满足所有要求。因此，标准试验方法的对象是那些对TRIBOLOGY不熟悉的人。该方法的提纲包括三种或四种不同的滑动副接触几何形式，并包括选择说明。日本和…对有关磨损试验的标准进行了综述更多的其他县。ASTM在美国有四种标准测试方法，DIN在德国有八种标准。而在日本，JIS有两个标准：塑料和陶瓷。ASTM与DIN的典型区别在于，ASTM包含了在特定磨损试验机上进行的特定接触几何磨损试验，而DIN则强调磨损试验的方法学描述，并计划进行循环试验。1994年，三所大学进行了初步试验，以确定滑动速度和接触压力等磨损试验条件。建议滑动速度和接触载荷分别为0.1m/S和10N。S50C碳钢试件需要进行仔细的热处理才能获得相同的硬度。1995年，6个组织参加了销盘式磨损试验，6个组织参加了两缸磨损试验，3个组织参加了环块磨损试验。遗憾的是，我们还没有完成实验。下一阶段的研究将在JSME委员会的指导下，在未来两年内提出标准磨损测试方法的草案。较少

This research project has studied on the possibility of the standardization of wear testing, with the activity of the research group on "Standardization on Wear Testing" in Japan Society of Mechanical Engineers, since 1994. Unfortunately, there is no standard wear testing method for metallic materials available in JIS when someone wants to examine the wear properties of new materials developed in an R&D process.We discussed the problems of standardization of wear testing and the objective of the test method. We concluded that the standard wear testing method can not satisfy all requirements, if proposed, because of various kinds of requirement for wear test. Therefore, the target of the standard testing method is those who are not familiar to TRIBOLOGY.The outline of the proposing method includes three or four different kinds of contact geometry of sliding pairs, and the instruction for selection is included.The survey of the standard related to wear testing has been made of Japan and … More other counties. ASTM has four standard testing methods in the US and DIN has eights standards in Germany. While, in Japan JIS has two standards ; for plastics and ceramics. Typical difference between ASTM and DIN is that the specific contact-geometry wear tests with specific wear testing machines are included in ASTM,and the methodological description for wear testing is emphasized in DIN.Round robin test was also planed. In 1994, three universities carried out it as a preliminary experiment to determine the wear test conditions such as sliding velocity and contact pressure. As a result, sliding velocity and contact load were recommended as 0.1m/s, and 10N.The careful heat treatment of S50C carbon steel speciments is required to obtain the same hardness. In 1995, six organizations attend to pin-on-disk type wear test, six to two-cycylinders, and three to block-on-ring. Unfortunately, we have not finished the experiments.The next stage of this research is to propose the draft of the standard wear testing method under the guidance of JSME committee in next two years.
