Title: Wear of Gas-Flame Composite Coatings with Tungsten and Nickel Matrix. Part I. Abrasive Wear
Keywords: HVOF-Coatings, Tribology, Abrasion Wear, Erosion Wear

Abstract: The object of the study is the characteristics of wear and wear-resistance of composite powder coatings, deposited by means of supersonic flame stream (or high velocity oxygen fuel spraying HVOF). Two types of coatings have been obtained – a group of powder composites based on tungsten matrix and a second group based on nickel matrix, whereupon each group includes coatings having different sizes of the powder particles. The coatings have been tested in two cases – in case of abrasion and in case of erosion. The present work consists of two parts. The first part represents the results on the characteristic features of wearing off during dry friction on the surface with fixed abrasive particles. Results have been obtained about the dependences of mass wear, the rate of wearing off, the wear intensity, absolute and relative wear-resistance under the same conditions of friction.
