Zusammenfassung: | Poly methyl methacrylate (PMMA) supported by 10 Vol.% (ZrTiAl2O7) nanoparticles gave it a code (ZTAO) in range (40 – 80) nm. The synthesis of nanocomposite specimens in terms of the volume fraction change of nano hydroxyapatite (NHA) (0,1,3,5,7,9) Vol% was carried out through technological processes to obtain the [NHA/( ZTAO)-PMMA] nanocomposites. Disc-on-disc method was adopted for wear and friction coefficients calculations according to standard conditions, by using a smooth steel disc 1045 that rotates at a speed of (120) rpm with a diameter of (4cm) as a counter face with a continuous load of 90 N for one hour. Hardness and density were used to help discuss the results. The biological tests, include the examination of the specimens in simulated body fluid (SBF) mixed with plasma riches palette (PRP). The specimens were placed and immersed in (SBF and PRP) for 60 days. The results showed that the coefficients of friction (μ) and wear (K) were improved with elevating the volume fraction of (NHA) which reached (μ=0.0781781) and (K=0.2698059×10−7). It can be concluded from the results that the [NHA/( ZTAO)-PMMA] nanocomposites were suitable as rebuild articular cartilage as well as orthopedic and prosthetic biomaterials in medical applications. |
