IMPROVEMENT OF HIGH TEMPERATURE WEAR RESISTANCE BY INJECTION OF OXIDE PARTICLES FOR Fe-BASE ALLOYS
吹喷氧化物质点改善铁基合金的高温耐磨性

The microstructure and mechanical properties of 1Cr18Ni9Ti, FeCrAl andCr25Ni20SiMn alloys after injection of oxide particles have been determined. The results showthat the tensile strength and hardness at room temperature or high temperatures, the high temper-ature rupture strength as well as the oxidation-wear resistance at high temperatures of the alloysincrease owing to the injection.
