Abstract A ball-milled mixture of glass and alumina powders has been plasma sprayed to produce alumina-glass composite coatings. The coatings have the unique advantage of a melted ceramic secondary phase parallel to the surface in an aligned platelet composite structure. The alumina raises the hardness from 300HV for pure glass coatings to 900HV for a 60wt% alumina-glass composite coating. The scratch resistance increases by a factor of three and the wear resistance by a factor of five. The glass wears by the formation and intersection of cracks. The alumina wears by fine abrasion and supports most of the sliding load. The wear resistance reached a plateau at 40-50vol% alumina, which corresponds to the changeover from a glass to a ceramic matrix. Keywords: glass composite coatings, wear, thermal spraying

Features of phase-structure formation and abrasive wear resistance of composite coatings “WC-M2 steel” worn against tungsten monocarbide have been investigated. It was established that adding 20 wt.% WC to the deposited powder mixture leads to the increase in M6C carbide content. These carbides show a multimodal size distribution consisting of~5.9 μm eutectic carbides along the grain boundaries,~0.25 μm carbides dispersed inside the grains. Also a greater amount of metastable austenite (~88 vol.%) is found. The high abrasive wear resistance of these coatings is provided byγ→α′-martensitic transformation and multimodal size distribution of reinforcing particles.

Abstract The purpose of this study is to investigate the microstructure and wear resistance of plasma sprayed WC-Co- Ni coatings. WC-Co-Ni composite powders were prepared by mixing of WC powder, Co powder and a Ni-P alloy powder, followed by sintering and crushing to improve the properties of plasma sprayed WC-Co coatings. In this study, their coatings were deposited by the atmospheric plasma spraying. The evaluation of their coatings were carried out by the observation of microstructure, measuring of microhardness values, adhesion strength values and an abrasive wear test. The abrasive wear resistance of the as-sprayed WC-Co-Ni coatings was comparable with that of WC-Co coatings deposited by HVOF spraying, and besides, the properties of the post-treated WC-Co-Ni coating were comparable with those of cemented carbides.
