HVOF Thermal Spraying – Thermal Spraying is a technique that consists in coating metal parts with a more or less thick layer of another material such as chromium carbide or tungsten carbide, without changing the mechanical characteristics. The coating thus obtained offers elevated mechanical characteristics especially in terms of hardness (up to 1000-1500 Hv300 ) and wear resistance. In particular with the HVOF (High Velocity Oxygen Fuel) technique, thanks to the different principle that generates the metallization, it is possible to achieve excellent results in terms of low porosity, high adhesion and elevated thicknesses. With the plants of 2 Effe Engineering it is possible to treat a large range of components, differing in size, weight and shape. The components usually coated are those that operate in a corrosive and stressful environment, for example, turbine blades and shafts, valves and so on. With this technique, thanks to the possibility of obtaining variable thicknesses, it is also possible to restore worn parts by metallizing them to their nominal dimensions. It’s possible to determine the phase analysis of coatings using a powder diffraction system included in laboratories of 2EFFE ENGINEERING.
