The powder stream temperature of a newly developed coaxial laser cladding technique have been calculated and measured in this study. A simplified one-dimensional model of the particle heating problem under laser irradiation was solved with various conditions of laser intensity, particle size and flow velocity. The experimental results have been successfully detected by a pinhole infrared sensor with the temperature calibration for hot particles. The thermal profiles of the coaxial nozzle give an optimum operation range of the stand-off distance for coaxial laser cladding.
