摘要：
We determine the melting point, hardness, and porosity of nickel powder alloys obtained by the method of hot pressing. A titanium content of 30–60 vol.% guarantees the wear resistance of alloys under the conditions of fretting corrosion. The heat resistance of these alloys was determined at a temperature of 1100°C and their wear resistance was found at temperatures of 20, 850, 950, and 1050°C. It is shown that, as the porosity increases, the heat resistance of the alloys decreases, and the characteristics of mean linear wear increase with temperature. We managed to obtain an alloy of the optimal composition with a melting point higher than 1300°C, which can be used in the aircraft industry.
