Induction cladding of alloys and metal-matrix composite coatings: A review

Induction cladding is a promising surface technology that combines the advantages of surface coatings and induction heating. It is an energy-efficient, environment-friendly, and cost-effective method that facilitates the fabrication of coatings with controllable thicknesses and ensures metallurgical bonding between the coating and the substrate. Owing to the high power-conversion efficiency of helical coil, induction cladding is particularly adaptable for the application of coatings on long shafts and rod parts, which find widespread use in mining and energy machinery. This paper provides a comprehensive overview of the state-of-the-art methods in induction cladding. Herein we focus on its mechanisms, cladding process and parameters, commonly used materials, simulations, innovative induction cladding technologies, industrial applications, problems, and future developments in this field.
