Abstract:In this paper, Ni-based amorphous composite coatings were fabricated under different heat inputs on a mild-steel substrate using laser cladding with coaxial powder feeding. The microstructure of the coating was studied using a scanning electron microscope (SEM), X-ray diffraction (XRD) and transmission electron microscope (TEM). The effects of the heat inputs on the amorphous-phase forming ability of the Ni-based alloy was investigated systematically with experimental and numerical simulation methods. The resu… Show more
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.
