Surface characterization and corrosion behavior of calcium phosphate-base composite layer on titanium and its alloys via plasma electrolytic oxidation: A review paper.

摘要: In recent years, calcium phosphate-base composites, such as hydroxyapatite (HA) and carbonate apatite (CA) have been considered desirable biocompatible coating layers in clinical biomedical applications implants because of the high resistance composites. This review focuses on effects voltage, time electrolytes a composite layer case pure titanium other grade alloys via plasma electrolytic oxidation (PEO) method. Remarkably, these parameters changed structure, morphology, pH, thickness crystallinity obtained for various engineering applications. Hence, structured caused improvement biocompatibility, corrosion assignment extra benefits Osseo integration. The fabricated with range 10 to 20 μm was evaluated physical, chemical, mechanical tribological characteristics XRD, FESEM, EDS, EIS analysis respectively, determine applied morphology phase transition. Moreover, it observed that during PEO, concentration calcium, phosphor shifts upward, which leads an enhanced bioactivity by altering thickness. results confirm crystallinity, contents can be applying thermal treatments. behavior investigated potentiodynamic polarization test body-simulated environment. Here, optimum process condition at 500 V 15 min Ringer solution. has summarized, aiming further development PEO producing more adequate titanium-base along desired features.
