摘要：
The wear behaviour on prealloyed sintered steel parts TiCN PVD coating was analysed. Cylindrical specimens (phi 40x30 mm(3)) were compacted to the green density of similar to 7.0 g.cm(-3). The specimens were sintered in pusher furnace at the temperature of 1180 degrees C for 40 minutes in an atmosphere of 25H(2)+75N(2). Part of sintered specimens was then coated by Physical Vapour Deposition. Wear tests were carried out by means of a pin-on-disk tribometer. The results of profilograms (the values of surface roughness) and the wear curves (mass loss versus sliding distance) showed positive effect of coating on the wear resistance of the tested specimens.
