Due to the low hardness and poor tribological behavior of titanium alloys, surface coating is a very critical technique in order to increase their commercial exploitation. In this case, Al₂O₃-based coatings are very promising for these alloys to improve their surface properties. To increase the absorption of the laser light in the visible range, MnO₂ is proposed as a dopant for Al₂O₃, in order to achieve dense coatings on Ti6Al4V substrates via cladding with a JK fiber laser. To ensure a homogeneous doping, MnO₂ and Al₂O₃ were dispersed by means of ammonium citrate, and to fully cover the substrate, spray dried MnO₂ doped Al₂O₃ granules were prepared and applied to the substrate. The effects of the solid loading on the properties of these granules were investigated. It is found that with 1.0 wt.% MnO₂ addition, a dense and uniform Al₂O₃ layer, accompanied with an interlayer, was successfully fabricated through laser cladding with low laser power of 20 W. Owing to the better adhesion on the substrate, Al₂O₃ coating on sandblasted substrates feature a higher hardness of 1204.1 ± 66.9 HV0.05 and an elastic modulus of 212.0 ± 11.8 GPa, which is an increase of 165.5 % and 53.3%, respectively, compared to the as-received substrate.
