Application of the newly developed technology in stainless steel for biomedical implant

摘要

The present invention pertains to a method of applying surface mechanical attrition treatment (SMAT) with a plurality of balls for treating surfaces of metallic alloys under a set of specific conditions in order to obtain a metal substrate with high yield strength and hardness, low cytotoxicity, high cytocompability and hemocompatibility suitable for medical implant. The plurality of balls used in the present invention comprises 316L stainless steel balls or zirconium oxide (ZrO₂) balls.
