摘　　要：为实现316L不锈钢冠脉支架光亮热处理,搭建了高真空热处理平台;调整热处理加热电压、加热电流、加热温度、保温时间,确定了高真空热处理工艺参数动态真空度3×10^-3-5×10^-3Pa;氩气保护流量10mL/min;热处理温度1020-1040℃;加热电压150V;电流15A,保温时间30s;探讨了加热温度与保温时间对冠脉支架组织性能影响,通入辅助气体快速冷却避免进入不锈钢敏化区间,同时引入金属网以获得光亮热处理样品。For carrying out the bright heat treatment of the 316L stainless steel coronary stent,a set of high vacuum heat treatment facilities was established. Optimized high vacauum heat treatment process and determined the processing parameters that are dynamic vacuum 3 × 10 ^-3-5×10^-3Pa, argon shield, velocity of flow 10 mL/min, heat treatment temperature 1020-1040℃, heating voltage 150V, heating current 15A, holding time 30s. Discuss the influences contribution to coronary structure property affected by heating temperature and holding time. In the presence of subsidiary gas quick cooling stainless and metallic network, stainless steel avoided getting into sensitization and had been brighten heat treatment.
