摘要：

In the presentwork, Ti3Al and Ni3Al coatings were carry out on AISI 1010 steel by pressure assisted combustion synthesis method in open atmosphere under an uniaxial pressure of 150 MPa at 1050 degrees C for 60 min. Starting powders were used titanium powder with 45 mu m size, aluminium powder with 15 mu m and nickel powder with 4-7 mu m size having 99.5, 99 and 99.8% purity, respectively. Microstructural examinations showed that the Ti3Al coating has multi-phase microstructure with porosity. The XRD patterns of the test sample indicated that the TiAl, Ti3Al, Ti3O and Ti phases. The hardness value of Ti3Al coating layer was about 520 +/- 6.9Hv(0.05). Microstructural and XRD examinations showed that the Ni3Al coating has only single-phasemicrostructure and Ni3Al phase is present. The hardness value of Ni3Al coating layer was about 377.7 +/- 20.6Hv(0.05).
