CARBIDE LAYERS PRODUCED IN VACUUM CHROMIZING PROCESS ON STEEL SURFACE COVERED WITH NICKEL ALLOYS CONTAINING CARBIDE-FORMING ELEMENTS
Journal Title: Tribologia - Year 2010, Vol 232, Issue 4
Abstract
In this paper duplex layers of the CrC+(Ni-W), the CrC+(Ni-Mo) and the CrC+Ni type produced on tool steel surface, in combined galvanic and vacuum chromizing processes, have been investigated. Studies of layers thickness, hardness and their morphology have been carried out. Tribological properties of the layers have been determined. It has been proved, that the wear resistance by friction of duplex layers of the CrC+(Ni-W) and the CrC+(Ni-Mo) type, produced in vacuum chromizing of steel covered with nickel alloys containing carbide-forming elements, is such good as carbides layers of the CrC type, produced on the steel surface without electrolytic coating. The high wear resistance of these layers has been proved, whereas tribological properties of the CrC+Ni duplex layers and the steel samples without any layers were not good.<br/><br/>
