摘要：
An amorphous layer was fabricated by laser alloying of the Ti-Al-TiB2-SiC-Y2O3 mixed powders on Ti-3Al-2V alloy in an open system. Results showed that a great number of the amorphous glassy phases were produced, which decreased the wear resistance of the alloying layer. It was found that the Mo addition decreased the glassy phase content and also refined the microstructure of the alloy layer, leading to the improvement of the wear resistance. This research provides essential theoretical and experimental basis to promote the application of laser alloying technology in the field of surface modification.
