Finite element analysis of the temperature field in laser cladding of Ni-based powders on teeth surfaces of the helical gear

Abstract

The temperature field formed in the process of laser cladding of worn teeth surfaces of the gear shaft is simulated by the finite element analysis software. Isothermal lines inside the tooth are obtained. Simulated results are compared with experimental data. Recommendations are given on improvement of the cladding technology to provide a durable continuous coating.
