Effect of Magnetic Abrasive Finishing on the Chemical and Phase Composition of TiC Coatings on VK8 Alloy

Powder Metallurgy and Metal Ceramics Aims and scope

Abstract

Using x-ray diffraction analysis and electron-probe microanalysis, we have studied TiC coatings obtained by chemical vapor deposition, where the base and subsequently the coating have undergone magnetic abrasive finishing. We have found that treating the base before the coating is deposited prevents an η phase (Co6W6C) from forming in the surface layer of coated platelets. Magnetic abrasive finishing (MAF) has been found to cause an α → β transition in the cobalt phase.
