Abstract

Abstract

The stresses in laser cladding of Ni₃Al-WC composite coating co and in heat affect zone (HAZ) σ_h have been induced based on considering the influences of laser processing parameters power P and beam traverse speed v.According to the calculated results, certain limits of P and v are necessary in order to obtain crack free coatings. It agrees well with the experimental results.
