| Abstract | 对表面纳米化和未经表面纳米化处理的316L不锈钢的样品分别进行点蚀实验和应力腐蚀对比实验,在3.5%(质量分数)NaCl水溶液中分别测出它们的极化曲线。结果表明,316L不锈钢表面纳米化后抗点蚀性能下降,抗应力腐蚀性能提高。对应力腐蚀断口的SEM分析发现,316L不锈钢应力腐蚀断口有明显分区现象,断裂形式为韧性断裂,开裂通道既有穿晶型也有沿晶型。 |
| Other Abstract | Pitting corrosion and stress corrosion tests have been carried out to the specimens of 316L stainless steel with nanocrystalline surface and non-nanocrystalline surface. Their polarization curves also have been measured in a 3.5 % （mass fraction） NaCl solution. The results show that pitting resistance of 316L stainless steel with nanocrystalline surface is reduced but the stress corrosion resistance is improved. The stress corrosion cracked surfaces of the specimens have been observed with SEM. It is found that the cracked surface of the 316L stainless steels has obviously zoned. The cracking shows a ductile fracture. The cracking path is both of intragranular and intergranular characteristic. |
