HVOF
HVOF: Chromium Carbide Coating, the Innovative Alternative to Hard Chrome Plating
The HVOF (High-Velocity Oxy-Fuel) process applies chromium carbide (Cr₃C₂) to parts requiring exceptional resistance to corrosion and mechanical impact. This coating is particularly recommended for demanding sectors such as automotive, mechanical engineering, chemical and petrochemical industries, energy, and hydraulics.
Unlike hard chrome plating, the HVOF process is not subject to REACH regulations. It therefore represents a sustainable and environmentally friendly solution, offering an effective alternative to hard chrome plating processes, while ensuring excellent wear resistance and increased part longevity.
The HVOF process projects particles at very high speeds, ensuring exceptional adhesion and high coating density. Thanks to this advanced technique, Chromium Carbide forms an extremely hard and durable layer, ideal for applications requiring enhanced protection against wear and corrosion.
Benefits
