Strength and Heat Resistance of New Antifrictional Powder Metallurgy Materials Based on Nickel

The hightemperature strength and heat resistance of new powder metallurgy antifrictional materials based on the powder metallurgy nickel alloy É:P975 were investigated. The effect of alloying elements on the structure and properties of the new materials at high temperatures was studied. It is shown that the developed materials can be successfully used in friction units operating at temperatures up to 900°C in air.
