GALLING TESTING SYSTEM

目前的资助申请寻求对磨损测试系统（GTS）的支持，该系统将允许人们在高温下对涂层和表面进行深入的摩擦学研究。磨损也被称为“冷焊”;它发生在一个材料表面与另一个滑动接触时，在高接触压力下，以如此强大的力粘附到另一个表面，使得一个或两个表面的一部分被撕裂，并且当部件滑动到一起时，两个表面都被损坏。润滑降低了磨损倾向，但材料的“抗磨损性”是指表面清洁且未润滑时的阻力。GTS将用于评估摩擦学和摩擦现象以及磨损机制，同时模拟机械部件的真实环境工作条件，包括在受控环境中接触和相对运动的不同材料。迫切需要GTS

The present grant application seeks support for a Galling Testing System (GTS) that will allow one to perform in depth tribological studies of coatings and surfaces at elevated temperatures. Galling is referred to also as "cold welding"; it occurs when one material surface in sliding contact with another, under high contact pressure, adheres to the other surface with such strong force that a part of one or both of the surfaces is torn away, and both surfaces become damaged when the parts slide together. Lubrication reduces galling tendency, but the property of "galling resistance" of a material refers to its resistance when the surface is clean and unlubricated. The GTS will be used to evaluate the tribological and friction phenomena as well as wear mechanisms, while simulating real-environment working conditions of mechanical components including different materials in contact and relative movement in controlled environments. The GTS is urgently needed
