Fractographical Analysis of Worn Surfaces od Duplex-coated P/M Vanadis 6 Ledeburitic Steel

Popis výsledku v původním jazyce

Duplex-coated P/M made Vanadis 6 ledeburitic steel was subjected to the wear testing at low and high load. After the testing, worn specimens were analysed by the fractography and connected methods in order to determine what happened during the sliding and why the wear resistance has shown very high dispersion of results. It was found that the samples differ one from each other in the adhesion of PVD-overlay on nitrided substrate. The specimens with good adhesion have shown a critical load of more than 130 N, wear of specimens was slow, wear of the counterparts very rapid and the worn surface manifested the occurrence of slightly worn CrN-overlay. On the other hand, if the coating was damaged, the wear rate of the specimen increased rapidly and the wornsurface showed the symptoms of massive cracking and total collapse of the coating. In addition, the samples exhibited differences in chemistry and phase constitution of PVD-layers.
