Cu-bearing stainless steel made by adding some copper to traditional stainless steels is an innovative class of structural/functional material.Its excellent and lasting antibacterial performance is mainly attributed to the precipitation of Cu-rich phases formed during proper solution and aging process.However,aging normally leads to the reduction of corrosion resistance,which restricts the practical application of Cu-bearing stainless steel to some extent.Therefore,in order to solve this problem and promote...
