主 题:plasma nitriding physical vapor deposition duplex surface treatment microhardness hydro-abrasive erosion wear
摘 要:The influence of duplex surface treatments consisting of a DC-pulsed plasma nitriding process and subsequent coatings of CrN and TiAlN deposited by physical vapor deposition(PVD)on AISI H13 tool steel was studied in this *** treated samples were characterized using metallographic techniques,SEM,EDS,and microhardness ***-abrasive erosion wear tests were performed in a specifically designed wear tester in which the samples were rotated in a wear tank containing a mixture of distilled water and ceramic abrasive chips with a fixed rotational *** wear rates caused by the abrasive particle impacts were assessed based on accumulated weight loss *** worn surfaces were also characterized using optical microscopy,SEM,and *** measurements indicated a significant increase in the surface hardness of the duplex-treated *** surfaces of the samples with the TiAlN coating were approximately 15 times harder than that of the untreated samples and 3 times that of the plasma nitrided ***-abrasive erosion wear results showed that the duplex surface treatments,especially the CrN coating,displayed the highest erosion wear resistance.
