Cu ions were implanted to A304 stainless steel by MEVVA ion source. Through heat treatment, the sample were detected by XPS and antibacterial test. The experimental results show that the sample has a high antibacterial rate: 97.6% for escherichia coli and 99.1% for staphylococcus aureu. The value state of Cu and O ion changes through heat treatment. The antibacterial mechanism is that Cu dispersed in precipitation phases absorb oxygen in bacterial.
