High velocity flame spraying, such as HVOF and HVAF, with cermet spray powders has recently come into wide use in the petrochemical, paper, automotive and steel industries, in addition to being a chrome plate alternative. The dernier great advance in cost and quality of the hard dense coatings with exceptional wear and corrosion protection has magnetism for everyone concerned in the field of surface modification including thermal spraying. It has been found that powder particle strength and grain size of ceramics, as well as particle size distribution and manufacturing route of cermet powders, have a great influence on the deposit efficiency and the property of the coatings. Furthermore, we have made it clear that the proper choice of substrates with harder surface is vital for increasing separation resistance of the coatings containing carbides. These contemporary points of view can enhance the quality of cermet coatings, which lead to the further prevalence of cermet powders using high velocity flame spraying.
