低温渗碳处理对G95Cr18马氏体不锈钢组织和性能的影响

摘要

For the first time,low temperature carburizing technology is applied to G95Cr1 8 martensitic stainless steel,and the properties of the surface layer and the microstructure of the matrix are studied.The results show that a substantial increase of surface hardness is obtained after low temperature carburizing treatment,and low temperature carburizing treatment has little effect on matrix microstructure,with slightly decreased hardness,maintaining the characteristics of martensitic stainless steel with high hardness.%首次将低温渗碳处理技术应用于G95Cr18马氏体不锈钢,初步研究了该处理工艺下渗层和基体组织的性能.结果表明,经低温渗碳处理后的G95Cr18马氏体不锈钢表面硬度大幅提高,该处理工艺对基体组织的影响较小,基体硬度有所降低,但仍保持了马氏体不锈钢高硬度的特点.
