Microstructure and properties of WC-Co coatings, modified by sub-microcrystalline carbides, obtained by different methods of high velocity spray processes
چکیده انگلیسی
Microstructure and basic mechanical properties of WC-Co coatings obtained by HVOF and HVAF technique were described in this paper. A standard powder of WC-Co 83-17 (Amperit526.074) type was used for coating deposition on steel substrate. Sub-microcrystalline TiC powder was used to modify coatings deposited from Amperit526.074. The aim of the investigations was to compare microstructure and selected mechanical properties of coatings deposited by different methods of high velocity spray processes. The influence of sub-microcrystalline additions on the basic mechanical properties of coatings was analyzed. Deposited coatings were characterized from a morphological point of view. Their overall quality, porosity and adhesion of coatings to substrate were described.
