摘要(Abstract)：

采用超声振动装置对经等温淬火热处理不同时间(4和72 h)后得到不同贝氏体含量的GCr15SiMoAl轴承钢进行空蚀试验,通过扫描电镜(SEM)、非接触式光学轮廓仪、能谱仪(EDS)等对两种试样的空蚀质量损失、空蚀表面形貌变化和微观组织演变进行观察以及分析。结果表明:随着等温淬火保温时间从4 h增加到72 h,试验钢中的贝氏体含量从32.4%增加68.4%,显著提升了其抗空蚀性能;两种试样的表面粗糙度均随着空蚀时间的延长而增加,其中保温4 h试样的粗糙度变化更为显著;空蚀600 min后,保温72 h试样的累计质量损失仅为保温4 h试样的68.9%,前者的平均空蚀深度约为后者的69.1%;在空蚀初期,损伤主要出现在晶界处,伴随微裂纹的形成,随着空蚀的进行,小尺寸空蚀坑逐渐出现;到空蚀后期,试样表面塑性变形加剧,晶界处的微裂纹沿晶界扩展,小尺寸空蚀坑合并为大尺寸空蚀坑。
