Iv. Frishberg et al., Recovery of damaged surface in operation of a friction pair in the presence of ultrafine copper alloy powder, METAL SCI H, 42(7-8), 2000, pp. 275-278
The process of recovery of a region of a surface with an artificially creat
ed defect in the form of a turned groove upon friction of a steel 40 - stee
l 20KhN3A pair in motor oil with an additive of ultrafine copper alloy powd
er is described. It is shown that the process of recovery is connected with
the formation of wear-resistant structures, which possess a high plasticit
y because they consist of very fine "copper-plated" wear particles. It is a
ssumed that the formation of such structures is a consequence of the low so
lubility of copper in the steel.
