In this study, experiments with various parameters were performed to apply laser cladding to the exhaust valve face of a marine engine and optimum conditions were derived. The used specimen was an actual exhaust valve, and the heat source was a high-power diode laser. Cladding was applied to the exhaust valve face using the optimum conditions, and a sound clad layer without internal defects, such as pores and cracks, was formed. The average hardness of the clad layer formed under the optimum conditions was higher than 529 Hv. Component analysis showed a very low dilution rate inside the clad layer.
