The Ni60 and SiC-Ni60 composite coatings were successfully obtained by high-frequency inductive cladding on the AISI 1045 steel surface. The influence of SiC nanoparticles on the morphologies, phase composition, micro-hardness, wear resistance and corrosion resistance of the coatings were investigated systematically. An ultrasonic-assisted method was pre-treated for homogenising coating. The performance tests of coatings indicated that high-quality metallurgical bonding was formed under the optimised parameters. The average micro-hardness of Ni60 and SiC-Ni60 coatings was 765.6 and 1072.4 HV, respectively. The corresponding wear resistance was also measured, and the composite coating showed a much lower friction coefficient and wear rate. The corrosion resistance of the coatings was evidently improved by the addition of SiC nanoparticles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
