| Abstract: | Fe-based composite coatings with different TiC content were prepared on high manganese steelsubstrates by laser cladding technology. The effects of TiC content on the chemical composition and properties ofthe cladding layer were studied. The results showed that the chemical composition of the cladding layer containsaustenite, M7C3 carbide, TiC precipitates and unmelted TiC particles. With the increase of TiC content, thehardness of cladding layer gradually increased, while the wear resistance firstly increased followed by decreasing. |
