چکیده انگلیسی
Duplex-treated AlTiN coatings were deposited by advanced plasma assisted arc (APA-Arc) technology on pre-plasma nitrided AISI-H13 steel substrates using different N2/H2 flow ratios. The microstructures and properties of the AlTiN coatings were comprehensively characterized and analyzed. The results show that the N2/H2 flow ratios can tailor the thickness of compound layer during plasma nitriding process and the bright nitriding layer without compound layer is achieved. The properties of duplex-treated AlTiN coatings are well improved compared with monolayer AlTiN coating. The adhesion of the AlTiN coating is well enhanced by duplex treatment process, and adhesion grade increases from HF3-4 for monolayer AlTiN coating to HF1 for composite coatings. Moreover, the composite coatings with various thickness compound layers show different load-bearing capacities, and the interfacial adhesion force of the composite coating without compound layer reaches 61 N. The hardness of AlTiN coating is also enhanced by duplex treatment with the highest hardness of 2935 HV0.05. Meanwhile, tribological properties of AlTiN coatings are also slightly improved by duplex treatments.
