Tungsten carbide coating applied to wear surfaces for extended service life — built to hold up under heavy, continuous use instead of wearing out early.
Our HVOF Process
How We Tungsten Coat Your Parts
We apply tungsten carbide with the HVOF (high-velocity oxygen fuel) process.
01
Pre-machine to sizeParts are ground and honed to .005–.007″ under finish size, ready for coating.
02
Grit blastThe surface is grit blasted with aluminum oxide grit so the coating bonds.
03
Build up the tungsten coatingTungsten carbide is applied by HVOF, building the surface back up past finish size.
04
GrindThe coating is ground to .0005–.001″ over finish size.
05
Hone to finishParts are honed to an 8–12 micro-inch finish.
Pump plungers and compressor rods are the parts we tungsten coat most often. We advise that your compressor rods be rehoned and new packing installed.
