abrasion wear resistance of selected HVOF sprayed WcCoCr coatings

Abstract

The HVOF (high-velocity oxygen fuel) technology is one of the most used processes for carbide-based coatings application. These coatings are suitable, for example, to replace hard chromium plating. In order to select the right coating for a given application, it is necessary to know the key properties. The aim of this study is to analyze and compare the abrasion wear resistance of HVOF sprayed coatings based on tungsten carbide (WC-CoCr). The structure of the coatings and their resistance to abrasive wear are analyzed and discussed.
