A Review on High-Velocity Oxy-Fuel (HVOF) Coating Technique
Thermal spraying is a technique for applying coatings with thicknesses ranging from 10 µm to a few mm over mechanical components to improvise distinct and particular functional features, such as resistance to wear and corrosion, compatibility with human health and safety, as well as a wide range of friction coefficients, and so forth. An average particle viscous enthalpic jet may be created with a particle size range of 0.01 nm to some µm. Among different thermal coating processes, high-velocity oxy-fuel coating is new in this family and one of the most rapidly used coating techniques and this technique can provide a heavily dense coating with a porosity level of < 1%. Moreover, HVOF coating possesses considerable adhesion and hardness value and can extend the life of coated equipment by improving wear, erosion and corrosion resistance properties. The used particles in this process carry higher potential energy and that ultimately helps to form a high-quality coating. With careful control over the cooling rate, this coating technique can deposit coating with thickness up to 1.5 mm to reduce residual stress.
