Abstract
A method of fusing an alloy-based material with a coating layer using a thermal spray process. The method includes determining a predetermined energization frequency of a high-frequency power supply unit based on a diffused area thickness (T1) and a non-diffused area thickness (T2) of the alloy-based material, inductively heating the alloy-based material and the coating layer to reach a predetermined temperature at the predetermined energization frequency of the high-frequency power supply unit, selectively heating the alloy-based material at the predetermined energization frequency within a penetration depth range of a total thickness (D2) of the alloy-based material to suppress an austenite transformation of at least a portion of the alloy-based material, and fusing the selectively heated alloy-based material with the coating layer by suppressing the austenite transformation of at least the portion of the alloy-based material.
