Our resin diamond wheels for HVOF carbide coating has enjoyed wide popularity in Canada, Turkey, Dubai, etc. Our products cover cylindrical resin diamond wheels , diamond internal grinding wheels and flexible diamond sand belts.
Thermal spraying is an industrial coating process that consists of a heat source (flame or other) and a coating material in a powder or wire form which is literally melted into tiny droplets and sprayed onto surfaces at high velocity. Thermal sprayed coatings uniquely enhance and improve the performance of the component.Thermal spraying can provide thick coatings (thickness range from 20 microns to several mm), over a large area at high deposition rate as compared to other coating processes such as electroplating, physical and chemical vapor deposition.
Thermal Spray Technologies Include
Flame spray (wire,rod,powder), Arc spray, Plasma spray (includes atmosphere controlled plasma spray), HVOF (high velocity oxygen and fuel spray) or HVAF(high velocity air and fuel spray), Detonation Spray, Cold spray

How to select diamond grinding wheel for thermal spray coating?
1. Abrasive : Diamond
Diamond has the features of high hardness and wear resistance, it is ideal for grinding most of coating material,especially ceramic coating and cermet coating.
2. Bond: Vitrified/Resin
Vitrified/Resin bond diamond grinding wheel has high grinding efficiency,long life,easy to dressing, high concentration and less grinding heat and blockage.
3. Grit:
Rough grinding ： 100#-200#
Finish grinding: #400-600#
