ANGLE OF SPRAYING AND MECHANICAL PROPERTIES OF WC-Co COATINGS PREPARED BY HVOF SPRAY TECHNOLOGY

Popis výsledku v původním jazyce

Thermal spraying is the effective technology that produces the coatings from 50 um to several millimeters in the thickness. In this paper the HVOF spray technology is discussed. This technology for its typical properties is most of all used for forming cermets coatings. WC-Co cermets coating was tested and its mechanical properties were studied. WCCo coatings were sprayed with five different angles (90°, 75°, 60°, 45° and 30°). The deposition angle is very important for resulting coating properties. Thedeposition angle influences most of all bond strength, coating cohesion and porosity of the coating. From this case the different properties for the five different deposition angles were expected. We directed our attention at the hardness measurements and indentation fracture toughness (IFT) measurements. The results of microhardness and IFT indicate on mechanical material properties in the influence of the deposition angle.
