Electrophoretically deposited and vacuum sintered mono bi and tri phasic bioceramic coatings on 316l ss implants

Abstract

There has been a tremendous increase in the use of implant to restore the bone functions and abnormalities arising due to fractures, cancer and other diseases. The ageing population across the world and frequent accidents due to rash driving of automobiles has further increased the demand for new materials and devices. Conventionally surgeons and physicians have adopted traditional methods but with the rapid changes in materials and technological advances on the instrumentation front have resulted in the availability of new devices designed with modern materials. Metallic materials such as stainless steel, titanium alloys and Co-Cr alloys are widely used for load bearing application due to excellent corrosion resistance and mechanical strength. One of the disadvantages is the onset of corrosion with the passage of time and the subsequent release of metal ions resulting in negative impact on the body leading to failure of implants. Moreover, after failure this implant has to be removed and the patient is subjected to a second surgery. Hence, there is a need to improve the corrosion resistance and provide the implant surface with a bioactive layer so that new bone formation can take place. newline
