The formation of transfer films in sliding contacts between steel polymers with filler compounds will be studied. The filler material will be chosen from low-melting inorganic compounds of three metals which readily dissolve in steel. It is anticipated that the flash temperatures at asperity contacts will promote decomposition of the filler compounds and that subsequent diffusion of the metal into the steel will promote bonding between the transfer film and the steel surface. Parallel sliding tests will be run against glass surfaces and against surfaces of different roughness to determine the relative amounts of mechanical and chemical bonding of the transfer film to the steel. The composition and structure of the transfer film will also be studied.

将研究钢聚合物与填料化合物之间滑动接触中转移膜的形成。 填充材料将从容易溶解在钢中的三种金属的低熔点无机化合物中选择。 预计粗糙接触处的闪蒸温度将促进填料化合物的分解，并且金属随后扩散到钢中将促进转移膜和钢表面之间的结合。 将针对玻璃表面和不同粗糙度的表面进行平行滑动测试，以确定转移膜与钢的机械和化学结合的相对量。 还将研究转移膜的成分和结构。
