Replacement Coatings
Significant attention has recently been given to the chrome
replacement industry and the use of HVOF systems to achieve this
objective. For the past few years, the Axial III has been used to
replace chrome in a number of applications. The materials of highest
interest have been WC-Co, Cr3C2-NiCr,
stainless steel and NiCrBSi. All of these materials are sprayed
with the Axial III at substantially higher feed rates and deposition
efficiencies than with traditional plasma or HVOF systems.
