Study on Standardization of Wear Testing

本研究项目自1994年起，配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研究。不幸的是，当有人想要检查在研发过程中开发的新材料的磨损性能时，JIS中没有提供金属材料的标准磨损测试方法。讨论了磨损试验的标准化问题和试验方法的目的。我们得出结论，标准的磨损试验方法不能满足所有的要求，如果提出，因为各种要求的磨损试验。因此，标准测试方法的对象是那些不熟悉摩擦学的人。该方法概述了三种或四种不同的滑动副接触几何形状，并给出了选择说明。对日本和其他国家的磨损试验标准进行了调查。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；用于塑料和陶瓷。ASTM和DIN之间的典型区别是ASTM中包含了使用特定磨损试验机进行的特定接触几何磨损试验，而DIN中强调了磨损试验的方法描述。还计划进行循环测试。1994年，三所大学进行了初步实验，确定了滑动速度、接触压力等磨损试验条件。因此，建议滑动速度为0.1m/s，接触载荷为10N。为了获得相同的硬度，需要对S50C碳钢试样进行仔细的热处理。1995年，6个组织参加了销盘式磨损试验，6个组织参加了两缸式磨损试验，3个组织参加了块环式磨损试验。不幸的是，我们还没有完成实验。本研究的下一阶段是在未来两年内在JSME委员会的指导下提出标准磨损试验方法的草案。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.
