Abstract: Nickel aluminide intermetallic alloys based on Ni3Al, because of their properties, belong to metallic materials between metals and ceramics. Out of the many interesting nickel aluminides properties, in comparison with high-temperature creep resisting nickel alloys, the most important are: high oxidation and carboration resistance, low density and high fatigue strength. The major purpose of research was the examination of chemical composition and structural properties effects on nickel aluminide abrasive wear. The test was taken for five chosen kinds of nickel aluminide intermetallic alloys containing: boron, zirconium, chromium, molybdenum, and iron. Metallographic analysis shows that each given alloy has complex phase and morphology structure which can be easily modified by adding different kinds and quantities of additives. All in all, based on the results of the tests, the conclusion is that the lowest resistance to abrasive wear is possessed by homogeneous structure alloys. In addition, hardness was discovered to have a strong effect on the abrasive wear resistance of nickel aluminides.

Keywords: Ni3Al intermetallic alloys, abrasion, surface layer, mechanical and physical properties.
