چکیده
In recent years, a wide range of studies have focused on the surface modification of titanium, especially in terms of itsbiomedical applications. However, comparatively less researches have been conducted on the fabrication of titanium surfacecomposites in bulk form. The primary objective of this investigation is to successfully produce hydroxyapatite (HA)-Tisurface composites with a homogenous dispersion of nano hydroxyapatite particles through friction stir processing (FSP).The secondary aim is to investigate the effect of FSP parameters, specifically filler mixture, on the microstructure andmechanical properties of the composites. Two different mixtures of HA and FSP parameters, traverse speeds of ۳۰ and ۴۵mm min-۱, rotational speed of ۱۲۰۰ rpm, and a conical tool shape, were used. It was found that the samples obtained by afiller mixture of HA-polyvinyl alcohol (PVA) showed better dispersion of HA in the Ti base, as well as higher tensilestrength. Also, a ۳۰ mm min-۱ traverse speed led to higher strength in both filler mixtures. Therefore, the sample producedby a traverse speed of ۳۰ mm min-۱ and HA/PVA filler mixture was selected as the optimum sample.کلیدواژه ها
