| Abstract: | Ti-6Al-4V alloy is of high specific strength and good anticorrosion resistance and is widely used in the aeronautic,astronautic,petroleum and chemical industries.Laser cladding of metal-ceramic composite coating on the surface will effectively and obviously enhance the properties of titanium alloy.The methods of XRD,SEM and EDS are used to analyze the microstructure of the NiCrBSi＋5wt%BN cladding layers.HV-1000 type vickers hardness tester is used to test the hardness of the cladding layers. |
