Problems solved by technology

However, the chemical method usually takes a long time and has poor controllability; while the electrochemical method has high treatment efficiency and strong film controllability
At present, the electrochemical surface treatment of medical porous metals is still focused on the research and development of non-conductive ceramic coatings, and the uniformity of deposition of non-conductive ceramic coatings (calcium phosphate, metal oxides) in porous metals is poor.
