Analysis of the Effect of Pre-oxidation Technology on the Microstructure and Properties of NiAl Laser Cladding Coatings
The effect of pre oxidation technology on the microstructure and properties of NiAl laser cladding coatings was studied.The experimental results show that after pre oxidation technology treatment,in addition to the NiAl main phase,the coating also added Al2O3 phase,and the hardness of the coating increased by about 20％,the friction coefficient decreased by about 23％,and the wear resistance was significantly improved.From this,it can be concluded that the NiAl laser cladding coating achieved a benign transformation from microstructure to performance through pre-oxidation technology,which has high practical application value.
