WebHigh-speed Friction and Wear Performance of NiCrAlY Coating Electrospark Deposited on CrNi3MoVA Steel YANG Junbao et al., Materials Reports, 2024 A Review on Design and Research Progress of Antifriction and Wear-ResistantMultilayer Coatings ZHENG Xiaomeng et al., Materials Reports, 2024 WebThe results indicate that NiCoCrAlYSiHf coatings substantially increase the high-temperature oxidation resistance of CrNi3MoVA steel and the oxidation process was retarded mainly by the presence of α-Al2O3 oxide scale on the coating. Meanwhile, the major diffusion occured between the substrate element Fe and the coating element Co …
