We suggested the deposition process of NiTi intermetallic compounds on carbon steel substrates using a plasma transferred arc (PTA) surfacing process. In order to prevent the formation of iron-based intermetallic compounds and hardening of the NiTi coatings, nickel interlayer was used during the PTA surfacing process.<BR>Nickel interlaying leads to the prevention of cracks and hardening of the NiTi coatings. The microstructure of NiTi-deposited metals features Ni<SUB>3</SUB>Ti phase and the grain boundary showing the eutectic structure of NiTi and Ni<SUB>3</SUB>Ti. The wear resistance of the NiTi coatings made by using the nickel interlayer is superior to the resistance of Stellite #6 coatings.
