In this research, in order to enhance wear resistance of commercial pure titanium, Ti-Al intermetallic compounds were cladding on the surface of titanium using gas tungsten arc welding method. For this purpose, the titanium powder was mixed with 25, 54 and 75 atomic percent of aluminum powder by using a ball mill. In the following, the obtained mixtures were mixed with an organic glue tragacanth and 2mm thickness of the mixtures were preplaced on the substrate and dried at 150 for one hour. Finally, the welding parameters were assumed constant and two currents of 80 and 100A were selected and six samples were cladding. To evaluate the created phases in the coating, X-ray diffraction (XRD) test was used. The results showed that in the both states of welding, with increaseing of aluminum, Ti(?)+? 2 , ? 2 ?+and ?+TiAl 2 phases were formed. Cross-sectional hardness of samples was prepared using micro-hardness test. The results showed that the increment of current intensity reduced the hardness of coating. In addition, the welded sample with the current of 80A and the phases of Ti(?)+? 2 had the most hardness (600 HV). The metallographic pictures of samples were used for measurement of dilution. Reducing the current of welding caused reduction in the dilution of the samples. In order to evaluate the fracture toughness of cladding samples, the hardness test was used. In addition to evaluate the wear resistance of samples, pin on disk wear test was performed with normal load of 10N. Then, the worn surfaces were examined by scanning electron microscopy. Investigations showed that the samples with ?+? 2 phases in both cladding cases had best wear behavior than others. Topographical investigation indicated that the dominant mechanism of wear was abrasive. Keywords: Ti-Al Intermetallic compounds,cladding, Commercial pure titanium, Gas Tungsten Arc Welding, Wear.
