Recovery of damaged sufrace in operation of a friction pair in the presence of ultrafine copper alloy powder

The process of recovery of a region of a surface with an artificially created defect in the form of a turned groove upon friction of a steel 40-steel 20KhN3A pair in motor oil with an additive of ultrafine copper alloy powder is described. It is shown that the process of recovery is connected with t...

Description
Summary:The process of recovery of a region of a surface with an artificially created defect in the form of a turned groove upon friction of a steel 40-steel 20KhN3A pair in motor oil with an additive of ultrafine copper alloy powder is described. It is shown that the process of recovery is connected with the formation of wear-resistant structures, which possess a high plasticity because they consist of very fine "copper-plated" wear particles. It is assumed that the formation of such structures is a consequence of the low solubility of copper in the steel.[PUBLICATION ABSTRACT]
