A Review on Fretting Corrosion of Modular Interfaces of Artificial Hip Joint

The fretting corrosion behavior of the modular interface of hip joints will directly affect the service life of artificial joint prosthesis.The basic principles of fretting corrosion of the modular interface of hip joints were summarized,the research progress of the five influence aspects on fretting corrosion of the modular surface,such as the combination of the prosthesis,combined interface materials,design parameters,surgical operation,and patient and physiological factors was introduced.The focus of future research was suggested,which is to establish a multi scale model of the artificial hip joint,to use experimental tests and simulation calculation methods to investigate the influence of conditions such as joint force,joint motion and sliding surface tribology,material matching,different design assemblies,environmental media on the fretting corrosion behavior
