Abstract:

OBJECTIVE: Medical stainless steel can not be replaced by other materials such as cobalt or titanium alloy, and compound bioceramic in the replacement and repair of hard tissues, but the metal ions that are released from medical stainless steel because of its corrosion and wear, result in harm and side effects, as well as embedding failure. Recently, there have been great improvements achieved in the research of corrosion, wear and biocompatibility for new types of medical stainless steel, and this improvement is generally focused day by day.
OBJECTIVE: To review the current statues in the corrosion, wear and biocompatibility of medical stainless steel, and to analyze the existing problems and development trends.
METHODS: Databases of CNKI and PubMed were retrieved by computer to search the papers published from January 1995 to January 2010. Papers underlying the corrosion, wear and biocompatibility of medical stainless steel were selected. Totally 39 literatures were summarized according to inclusive criteria.
RESULTS AND CONCLUSION: The treatment modifying the surface of mental materials and the appearance of the medical stainless steel without nickel would improve corrosion and wear of the medical stainless steel, and eliminate harm effect of mental ions such as nickel. But now the complex techniques that improve the corrosion and wear is still absent. The medical stainless steel without nickel has better characteristics of comprehensive ability and biocompatibility, as well as better development prospect. All kinds of factors must be considered in development and application of the medical stainless steel, and the materials must be satisfying in the all aspects of corrosion, wear and biocompatibility at the same time. It is also important to construct and consummate the system that assesses the materials efficiency.
