Multiple ceramic particle reinforced iron matrix coatings were produced by laser beam melting mixture of B 4 C, TiO 2 , Al, and Fe-based self-melting powders. The results showed that the coating were mainly composed of a-Fe, TiB 2 , and TiC. TiB 2 grains showed rectangle structures with deep grey, and that TiC grains exhibited near-cubic morphologies with light grey in the coating. The amount, type, and size of the reinforcements were influenced by the content of B 4 C, TiO 2 , and Al. Compared to the substrate, wear resistance of the composite coatings were significantly improved. Furthermore, the coatings possessed more effective protection for scratching and plastic deformation.
