Ti-Fe alloy coatings with different Nb4Si additions are prepared by laser cladding on TA15 alloy. The influence of Nb4Si content on microstructures and properties of the coatings are investigated by means of X-ray diffraction, scanning electron microscopy (SEM), microhardness tester, nano-indenter, and frication wear testing machine. The results show that the coatings with different Nb4Si additions mainly consist of β-TiNb dendrite and β-TiNb+TiFe eutectic. However, what has changed is that with the increase of the Nb4Si addition, the content of the eutectic presents the trend of first increasing then decreasing, namely, the highest value is obtained when the atomic fraction of Nb4Si particles is 2.0%. Another change in the microstructure is that a small amount of β-(TiNb)5Si3 phase is formed when the atomic fraction of Nb4Si addition is beyond 0.5%. When the atomic fraction of Nb4Si addition is 2.0%, the hardness, friction and wear properties of the coatings all reach the highest, while the elastic module is the lowest, as a result of high eutectic content.
