In view of poor oxidation resistance of Ti6Al4V, the composites coatings prepared by laser cladding were used to solve the above shortcoming with a mixture of NiCrBSi and 5 wt%- 30 wt% Si as the cladding material. The investigation into the evolution in microstructure, mechanical properties and oxid...
