摘要：

The Stellite SF12-TiC-Mo-Sn laser melt deposited (LMD) composite coating was produced on a TA1 titanium alloy. Such composite coating was researched using scanning electron microscope (SEM) and a high-resolution transmission electron microscope (HRTEM). It was confirmed that Ti3Sn nanocrystals appeared at an intersplat region, which was very compatible to the d-space of the Ti3Sn at an orientation of (101). The Ti3Sn particles were surrounded by the amorphous phases. Under the action of such composite coating, the micro-hardness distribution of the substrate surface is in a range of 1350-1500 HV0.2, and the wear volume loss is 1/13 of a TA1 alloy.
