Investigation of the structure and properties of reinforced additive products obtained from electroerosive cobalt-chromium powder

The analysis of the wear resistance characteristics of samples sintered from high-chromium electroerosive powders obtained in kerosene on a friction path of 500 m is performed. It was established experimentally that: there is a partial wear of the counterbody and the buildup of the products of wear of the sample on centralo; the magnitude of the wear track of the sample is 383,1 µm to 473,5 mm; the depth of the profile grooves of the wear surface of the sample is 5 microns; the coefficient of friction of the surface of the sample is from 0,228 to 0,826; the wear rate of the counterbody made of Stainless Steel AISI 420 and the sample made of sintered steel 12X17 are 0.016 and 1.138, respectively.
