Effect of TiN coating on microstructure of Tif/Al composite

► A TiN layer was coated on Ti fibres by an arc ion plating method. ► Prefer orientation of TiN on (1 1 1) and (2 0 0) was found. ► After coated with TiN layer, no significant reaction layer was found in (Tif + TiN)/Al composite. ► Small discontinuous needle-like TiAl3 phases were detected at TiN/Al interface.
