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.

研究了钢聚合物与填料之间的滑动接触中转移膜的形成。填充材料将选择三种金属的低熔点无机化合物，这些金属易于溶解于钢中。预计在粗糙接触处的闪蒸温度将促进填料化合物的分解，随后金属向钢中的扩散将促进转移膜与钢表面之间的结合。平行滑动试验将在玻璃表面和不同粗糙度的表面上进行，以确定转移膜与钢的机械和化学结合的相对量。并对转移膜的组成和结构进行了研究。
