HVOF
HVOF: Tungsten Carbide Coating, the ultimate solution against abrasion and mechanical shock
The HVOF (High-Velocity Oxy-Fuel) process allows the application of tungsten carbide (WC) to parts requiring exceptional resistance to abrasion, mechanical shock, and intense wear. This coating is particularly recommended for demanding industrial sectors such as automotive, mechanical engineering, chemical and petrochemical industries, and the energy sector.
The tungsten carbide coating is designed to provide long-lasting protection even in the harshest environments, thanks to its high hardness and exceptional adhesion. The HVOF process ensures particle projection at very high speeds, guaranteeing a dense and homogeneous layer, resistant to impacts and mechanical stress.
