采用先进的等离子注入技术,对304不锈钢分别进行N、Ti、Al离子注入,对比研究了304不锈钢注入不同种离子后的表面耐腐蚀性。研究了离子注入后各试样的表面微观形貌、物相成分和电化学腐蚀性。结果表明:离子注入304不锈钢的表面组织平整、致密。但随着注入剂量的增大,表面光洁度降低, 形成多孔形貌; 适量的离子注入剂量可获得非晶态注入层,形成单相过饱和固溶体,提高不锈钢的耐腐蚀性;相较两种注入剂量,剂量为5×10~(17)ions/cm~2的各离子注入试样,耐腐蚀性提高;而相同剂量的各离子注入试样, Ti离子注入的效果最好,相比304不锈钢基材,耐腐蚀性能约提高了72%(剂量为5×10~(17) ions/cm~2), 其次是注...

The advanced ion implantation technology was used to implant 304 stainless steel with N, Ti and Al ions. The surface corrosion resistance of the steel after ions implanted was studied. The surface morphology, phase composition and electro chemical corrosion of the samples after ions implanted were analyzed. The results show that: the microstructure of ions implanted 304 stainless steel is flat and compact.But with the implantation dose increasing, the surface finish reduces and a porous morphology forms; the appropriate amount of implantation d...
