Numerical Simulation and Experimental Verification of Ultra-High Frequency Induction Cladding with Metal Wire

Abstract

This paper proposes a novel approach of ultra-high frequency induction cladding with metal wire, in which AISI type 316L stainless steel wire (SS316L) is coated on gray cast iron to improve the specific surface properties of gray cast iron. The corresponding numerical model coupled with electromagnetic field and temperature field has been developed to obtain the representative distribution of induction heat. The established numerical model has been validated experimentally, and the temperature distribution captured in experiment shows good agreement with the calculated results. Given the high heating efficiency and selective heating characteristics of ultra-high frequency induction cladding technology, this method can be applied to the micro-crack repair on the surface of the thermal-sensitive materials.
