Superalloy cladding has been widely used for high-temperature structural applications. From consideration of sustainable materials engineering and product performance, superalloy cladding becomes ever attractive manufacturing methodology related to high-temperature materials applications. Laser-beam cladding process is often preferred as involving fabrication of precision engineering components or equipment. Jonesite 19 is a Ni-Nb intermetallic-matrix superalloy which holds sustained mechanical and metallurgical properties at or above 900°C. The claddability of Jonesite 19 is studied applying laser-beam process. The substrate materials utilized in this investigation include heat resistant alloys J130 and J160. Examination on dilution of fusion zone, bonding strength of dissimilar alloys, and characterization of heat-affected zone in laser cladded cylindrical samples is conducted. A comparative assessment of Jonesite 19 and HB400 cladded J130 and J160 is discussed.
