Nano-mechanical properties of an advanced duplex system based on CrN coating on active screen plasma nitrided 42CrMo4 steel
Active screen plasma nitriding (ASPN) attracted interests from researchers and industries as it can overcome several intrinsic problems in direct of direct current glow discharge plasma nitriding (DCPN) such as arcing, hollow cathode, edge effects and the strong temperature dependence on the shape of the samples. In this study, an advanced duplex system based on active screen plasma nitriding and CrN coating was synthesized on 42CrMo4 steels. The effects of ASPN on the mechanical properties, nano-impact resistance, scratch resistance in different load ranges were investigated. The results show that the surface hardness (H), reduced elastic modulus (Er), the ratios of H/Er and H3/Er2 can significantly be improved at the testing load range from 5mN to 100mN. The enhanced nano-impact and scratch resistance can well correlate to the improved H/Er and H3/Er2.
