ENABLE THE POSSIBILITY OF DEPOSITION ON SS SUBSTRATE COATING POWDER MIXTURE COMPOSED OF TITANIUM (TI CP) AND PTFE THROUGH FLAME THERMAL SPRAY PROCESS
ResumoImproving prosthesis performance used as orthopedic implants has been a trend in recent years. Though there is still space for improvements, due to the implant loss and high failure rate. An alternative to accomplish such refinement is the surface modification in the form of coating. Stainless steel (SS) biomaterial may have potential to be used in implants for consolidating bone fractures if their bioactivity is improved. Thus, samples of SS were coated with a coating powder mixture composed of titanium (Ti cp) and polytetrafluoroethylene (PTFE) through the flame thermal spray process, using nitrogen as carrier gas. All coatings were coated 68 ?m thicknesses. The coatings were characterized by scanning electronic microscope (SEM) and energy dispersive x-ray detector (EDS). Ultimately, the results of the analysis confirm the created of composite coating (PTFE-Ti) on SS and It will may reveal the potential this material.
