HVOF Thermal Spray Coating Services

Industrial Plating Company uses a unique line of powders specifically engineered for HVOF thermal spray coatings. The bond strength of these coatings is typically higher than those achieved with other thermal spray methods. HVOF Coatings have been shown to display superior wear, which can be attributed to the unique combination of higher hardness, higher density, and low porosity levels. Our HVOF Coating Services typically provide up to 5x the resistance to wear and particle erosion as their Plasma applied equivalents. The most common HVOF coatings are Tungsten Carbide and Chromium Carbide coatings.

Tungsten Carbide Coatings

The HVOF coating process produces Tungsten carbide coatings that are very dense and very adhesive. Coating particles are applied at a very high speed in a molten state and bond instantly to the substrate. Tungsten Carbide is almost twice the strength of steel with double the density which makes it a great solution for extreme wear environments. HVOF Tungsten Carbide coatings have the following characteristics:
Tungsten Carbide coatings deposited utilizing HVOF thermal spray coating technology can provide excellent wear resistance and anti-galling characteristics for an array of industrial applications. Various carbide particle sizes, material composition and processing techniques are employed that allow us to produce coatings tailored to each applications needs.

Chromium Carbide Coatings

Chromium Carbide offers wear resistance in high temperature environments. It is an excellent alternative to tungsten carbide coatings depending on the operating environment. Chromium Carbide coatings provide less wear resistance than tungsten carbide, however it can offer better heat and oxide resistance at higher temperatures under corrosive conditions.

Chromium carbide coatings are good candidates for applications with high temperature environments ranging from over 1004F to 1499F (540 C to 815 C) requiring resistance to abrasion, cavitation, fretting, or particle erosion.
