Features of thermal spray

hvof tungsten carbide and chrome carbide coatingsWide Materials Choice
Metals , Alloy blends, carbides, ceramics..
Uniform Coating Thickness - 0.02 to few mm
Selective coating capability by masking
In situ coating capability - paper /power
Coatings with high performance: 60Rb-72Rc
No metallurgical change in Base material

Benefits of Thermal Spraying

Low Capital Investment - Compared to a plating and vacuum installation.
Competitive Application Costs Selective coating allows cost control
When parts are large enough and the coating performance requirement is high, thermal spraying
    becomes very cost competitive.
Environmental: Most importantly the effluent treatment plant is not required. All required is a good dust
    collector.
