High Speed Steel Cladding by PTA - Influence of Parameters
Original language description
PTA surfacing is widely used technology of increasing lifespan and wear resistant characteristics of machine components. There is a wide range of alloys which can be used as filler material; however, plasma cladding of High Speed Steel (HSS) is not yet frequently used. HSS’s are the materials for fabrication of tools in machining, forming, forging and in other applications where high wear resistance is needed. The deposit tested in this study was cladded with three different frequencies of plasma current. Two-layer deposits were studied metallographically and tribologically. It was found that hardness of deposits is higher than 750HV, and structure contains finely distributed carbides of vanadium, chromium, molybdenum and tungsten. Tribological testing was performed on dry sand/rubber wheel apparatus and it was found that wear resistance depends on frequency of plasma current.
