INFLUENCE OF HVOF SPRAYED COATINGS ON FATIGUE PROPERTIES OF COATINGSUBSTRATE SYSTEM
Original language description
This research deals with the influence of thermally sprayed HVOF (High Velocity Oxygen Fuel) coatings on fatigue life of components. HVOF coatings are now a widespread technology commonly used for additional treatment of component surfaces. The advantages particularly consist in achieving of low coating porosity, high adhesion to the base material and residual compressive stress in the surface coating layer. The main application areas of HVOF coatings are applications requiring high surface hardness and wear resistance (pistons, rods, cylinder presses, etc.). Two coatings were evaluated in this study - carbide based coating (Cr3C2-NiCr) and alloy based coating (Stellite 6). The tests were carried out at room temperature and at 600 °C. The main contribution of this paper is to evaluate the coating influence on fatigue properties of coating-substrate system in comparison with the fatigue properties of the substrate itself. In particular, it was examined whether and how the increase or decrease of fatigue properties occurs in this system. The obtained results prove that both evaluated coatings reduce overall fatigue resistance; however, by Stellite 6 coating the reduction of fatigue properties is not so noticeable.
