This work is based on the dry sliding wear of Stellite 4-FeSi-B4C composites deposited on a TA10 titanium alloy using a Laser melting deposition (LMD) technique, the parameters of which are such as to provide almost crack-free composites with very low porosity. To our knowledge, it is the first time that Stellite4-FeSi-B4C mixed powders are deposited as the hard composites by the LMD technique. Scanning electron microscope results indicate the nanoscale particles and nanorods are produced in such composites. Furthermore, due to the characteristics of the laser technology, the ultrafine nanoscale polycrystalline phases can be easily produced. Compared with a TA10 alloy substrate, the improvements of the micro-hardness and wear resistance are obtained for such composites.
