【摘要】 采用18Cr2Ni4WA钢,在气体渗碳炉中,碳势为10%,920℃的条件下进行5h渗碳,对试样重新加热淬火,并通过回火、冷处理等方法改变渗层中的奥氏体量。研究了渗层中的奥氏体在摩擦磨损过程中的相变行为及相变对金属间边界润滑磨损特性的影响。更多还原

【Abstract】 Different retained austenite contents were obtained in 18Cr2Ni4WA steel that had been carburizing under the condition of 1 0% carbon potential value and temperature 920℃ for 5h in gas carburized furnace by quenching,tempering and sub zero treatment.Some work has been done about the austenite transformation and the affection of the transformation on boundary lubricated wear property.更多还原
