Alloy design with intermetallic phase matrix is an emerging trend for high temperature applications. Alloy J513 matrix is composed of multiple phases including intermetallic, martensitic and boride. Owing to its excellent wear resistance, J513 has been widely used for combustion engine valvetrain applications.
J513 is an iron rich alloy which possesses a good weldability with iron-based or nickel-based alloys. J513 can be readily atomized with gas, water and centrifugal spin approaches to obtain particulate materials for sintered powder metallurgy, 3D metal printing, and metal cladding applications.
J513 cladded samples made with plasma arc welding and laser beam welding processes were examined. Good wear resistance of J513 cladded samples was revealed by Plint wear test. The results obtained from this study can be useful for cladding ability investigation of other intermetallic matrix alloys such as Jonesite 19 and Jonesite 21.
