Abstract
This work investigates the using thermal spray coating by Flame as a method to produce high performance cerment coating. In this study , an alumina was added to the self bounding of Ni- Al .This cerment composite materials sprayed through aflame towards a graphite substrate . The aim of the work is to see the effective of laser treatment on the microstructural of the coating layers . The results show that coating consists of different morphology zones surface defects and pores . The laser analysis predicts that remelted all surface particles with a significant high surface tension , producing strongly hardness with improvement in the structurel and mechanical properties.
