Abstract

High-temperature self-lubricating wear-resistant metal matrix composite coatings are fabricated on substrate of a γ-TiAl intermetallic alloy Ti-48Al-2Cr-2Nb by laser cladding. The hybrid γ-NiCr metal matrix composite coating is mainly reinforced by rapidly solidified wear-resistant phase of hyper-eutectic M₇C₃ and self-lubricating particles of Ag and CaF₂ or CaAgF₄. Microstructure and hardness within the whole laser clad composite coating is homogeneous and the bonding to the substrate is purely metallurgical. Both hardness and dry sliding wear resistance of the γ-TiAl intermetallic alloy are significantly enhanced after laser cladding treatment.
