摘要

The microstructural,mechanical and corrosion properties of different cold-rolled biomedical nickel-free highnitrogen stainless steels (NFHNSSs) were investigated to study the effect of cold deformation on its dry wear resistance as well as corrosion-wear behaviors in distilled water and Hank's solution.The results indicated that NFHNSS was characterized by stable austenite and possessed excellent work-hardening capacity;due to increasing cold deformation,the corrosion resistance just decreased very slightly and the dry wear rate decreased initially but subsequently increased,while the corrosion-wear resistance was improved monotonically in both distilled water and Hank's solution in spite of the presence of corrosive ions.The friction coefficients for different cold-rolled NFHNSSs were very close under the same lubricating condition,but they were the largest in distilled water compared to that in dry wear tests and Hank's solution.
