Characterization of the surface deposition on anodized-hydrothermally treated commercially pure titanium after immersion in simulated body fluid

Abstract

The results indicate that the deposits formed on SA-treated c.p.Ti surfaces contained calcium phosphate. These deposits may be formed as a consequence of the topography and physicochemical properties of SA-treated c.p.Ti surfaces and may play a key role in osteoconduction during osseous wound healing.

Electroless Ni–B Coating of Pure Titanium Surface for Enhanced Tribocorrosion Performance in Artificial Saliva and Antibacterial Activity

“…Thus, numerous strategies focusing on the surface modification of Ti alloys have been employed to render them protection from both wear, corrosion and even tribocorrosion [3][4][5]. The strategies include physical vapour deposition [6], thermal spray [6,7], ion or laser nitriding [8][9][10], thermal oxidation [11,12], micro-arc oxidation [13][14][15], diffusion [16] and anodic oxidation treatments [17]. On the other hand, the antibacterial properties are also necessary for Ti implant RESEARCH when exposed to the living tissue [18].…”

Advances in calcium phosphate coatings - anodic spark deposition: a review

“…(42) claimed that anodization using Ishizawa and Zuhs' methods did not result in mineralized surfaces after SBF soaking for 14 days. Recently, (69) found that apatite formation on anodized titanium formed at 350 V in 0.01M beta-GP and 0.15M CA after 28 day soaking in SBF. However, (42) two-step method followed by soaking in SBF resulted in a new mineral phase after incubation of only 6 days in Vogel's SBF.…”

“…Further cellular work with hydrothermal treatment in steam at 300ºC for 2 hours, as in Ishizawa's method, was carried out by Takebe and others (5,23,24,36,69,73,74) using 0.01M beta-GP and 0.15M CA as the electrolyte during anodization. Using murine spleen cells and human peripheral blood mononuclear cells, no influence was observed in terms of LPS-induced proliferation of lymphocytes or LPS-induced IL-1α production between the treated AOFCP, AOFCP plus hydrothermal treatment and the untreated titanium cultured for up to 66 hours (23).…”

“…Additionally, the electrolyte concentrations during anodization do not reflect the refined values attained by Ishizawa and associates. In both (25) and (42) studies, the electrolyte was 0.03M beta-GP and 0.06M CA as in (75), and although initial work by Ishizawa (21) recommended this concentration, Takebe and others consistently describe using 0.01M beta-GP and 0.15M CA as the electrolyte medium (5,23,24,36,69,73,74). Clearly, altering the anodization voltage or concentration (and type) of the electrolytes will influence cellular responses as well as the mechanical properties.…”

Electrochemical and biological characterization HA/Al2O3‐YSZ nano‐composite coatings using electrophoretic process

“…Among different Caps, HA [Ca 10 (PO 4 ) 6 (OH) 2 ] is widely used due to its osseous nature and suitability to strong bonding with host bone tissues . Different coating methods have been utilized such as plasma spraying, dip coating, hot isostatic pressing, ion beam‐assisted deposition, pulsed laser deposition, sol–gel technique and electrophoretic deposition (EPD) . Among of these methods, EPD has several benefits such as better control thickness and morphology of the coating, components with complex shapes are deposited uniform, higher deposition rate than other coating technics and cheap equipment required …”
