A five-layer overlaid Ta2O5dense ceramic coating was successfully fabricated on a pure Ta substrate using laser cladding. The coating exhibits a graded microstructure with a single phase of α-Ta2O5formed towards the top of the coating, and was metallurgically bonded to the Ta substrate. Both the coating and the coating-substrate interface region were free from porosity. The development of the coating's microstructure was discussed based on an existing Ta-O phase diagram.
