Abstract:In the paper, the effect of voltage increase (from 500 V DC up to 650 V DC ) on the structure and chemical composition of the porous coating on titanium made by Plasma Electrolytic Oxidation is presented. Phosphates-based coatings enriched with calcium, magnesium, zinc, and copper in electrolyte based on 1 L of 85% concentrated H 3 PO 4 , with additions of Ca(NO 3 ) 2 ·4H 2 O, and Mg(NO 3 ) 2 ·6H 2 O, and Zn(NO 3 ) 2 ·6H 2 O, and Cu(NO 3 ) 2 ·3H 2 O, are described. The morphology and chemical and phase composition are evaluated using SEM, EDS, XRD, XPS, GDOES, and CLSM. Based on these analyses, it was found that PEO coatings are porous and enriched with calcium, magnesium, zinc and copper. They consist mainly of the amorphous phase, which is more visible for higher voltages; this is correlated with an increase in the total PEO coating thickness (the higher the voltage, the thicker the PEO coating). However, for 650 V DC , an amorphous phase and titanium substrate were also recorded, with a signal from Ti 2 P 2 O 7 crystalline that was not observed for lower voltages. It was also found that all obtained coatings may be divided into three sub-layers, i.e., porous, semiporous, and transitional.

Sowa et al 50 studied the bioactivity of anodic oxide coatings on Ti-13Nb-13Zr and human bone marrow derived mesenchymal stem cells (hBMSCs) were used to evaluate the biocompatibility. SEM and AFM analysis were carried out to illustrate the surface morphology.…”

Titanium (Ti) and Ti-based alloys are the best promising orthopaedic metal transplants. The Young's modulus of Ti and bone are nearer and so Ti implants are known as osseointegrated implants. However, the need for enhancing the osseointegration, corrosion resistance and biocompatibility cannot be ruled out in promoting the Ti as a golden standard. This review describes various surface modifications like acid etching, sand blasting, surface coating, alkali-heat treatment, plasma treatment and ion implantation of Ti-based implants which are the best solutions to promote biocompatibility, osseointegration and ultimately the longevity of implants. In addition, it gives an outline to accomplish the risky task in orthopaedics like recovering skeletal function by replacing the damaged bone for human being survival and it will assist the energetic collaboration of specialists in materials science, chemistry and biology for the quality enhancement.

“…This is mainly due to their excellent biocompatibility, good corrosion resistance, and chemical stability, as well as good tensile and fatigue strength, which results in a high strength to weight ratio [2][3][4][5][6][7]. In the last decade, two phase (α+β) Ti6Al-4V and Ti-6Al-7Nb alloys have been extensively used as metallic implants in biomedical engineering.…”

In this study, chitosan coatings were electrophoretically deposited (EPD) on near-β Ti-13Nb-13Zr alloy. The influence of colloidal solution composition and EPD parameters on the quality of chitosan coatings was investigated. It was established that the uniformity of as-deposited chitosan coatings is highly dependent on the chemical composition of the solution used for EPD, the pH, electrophoretic mobility and zeta potential of chitosan colloidal molecules, as well as EPD parameters, such as potential difference value and deposition time. The microstructure of the coatings was investigated using electron microscopy and X-ray diffractometry. The coatings 350 nm thick were homogeneous and exhibited an amorphous structure. The coatings had low hardness and Young’s modulus. The effect of surface of the substrate preparation prior to coating deposition on the adhesion of chitosan coatings to the Ti-13Nb-13Zr alloy was also investigated. The coatings exhibited good adhesion to the non-acid-etched surface of the titanium alloy.
