“…The biotolerance of titanium anodized in a solution containing calcium and phosphorus can be additionally improved by means of a hydrothermal treatment [25][26][27]. Moreover, the application of plasma electrolytic oxidation in solutions containing calcium and phosphorus leads to an increase of corrosion resistance of titanium in physiological saline solutions [18,28,29]. The purpose of the study is to identify the possibility of implanting calcium and phosphorus into an oxide film formed on titanium during anodizing in a new electrolyte and to determine the corrosion resistance of the so modified titanium.…”

“…The coating method of ionized particles increases by the effect of the flow frequency. Increased ionization permits low deposition pressure [44]. When the DLC and MAO/DLC duplex coatings grow, the high substrate voltage and high frequency are applied.…”

In recent years, various technologies have been increasingly investigated for the surface modification of Ti and Ti alloys. Microarc oxidation (MAO) is one of the effective techniques to improve surface properties. However, it has some disadvantages for sliding wear applications and/or aggressive environments. In this study, the combined MAO and closed field unbalanced magnetron sputtering process was used to deposit duplex MAO/diamond-like carbon (DLC) coatings on Ti 6 Al 4 V alloy. Analysis of the microstructures, morphology, and crystallographic structure were performed by using a SEM, Raman, and XRD. The wear, corrosion, and tribo-corrosion properties of the coatings were investigated using the pinon-disk wear test, potentiodynamic polarization test, and combining tribo-corrosion test unit, respectively. The results of this study have shown that duplex MAO/DLC coatings exhibit better wear, corrosion, and tribo-corrosion properties than the DLC or MAO monolayer on Ti 6 Al 4 V alloy substrate. MAO/DLC coatings exhibited dense structure, lower coefficient of friction and corrosion current density, and higher tribo-corrosion resistance. The results have also shown that MAO/DLC duplex coatings on Ti 6-Al 4 V substrates increased the tribo-corrosion resistance by acting as a barrier layer.

“…PEO is capable of converting metallic titanium into a ceramic layer of titanium oxide at room temperature (Yerokhin et al 2002;Baszkiewicz et al 2005;Rudnev et al 2005;Yao et al 2008;Song et al 2009). This method was used for Al and its alloys (Wang et al 2009;Godja et al 2010), aluminum coatings (Wu et al 2007) and Mg alloys too (Duan et al 2007).…”

“…If the rutile or higher corrosion resistances is the aim of the process, the more controlled conditions must be used. For achieving these goals, choosing suitable solutions is of primary importance (Yerokhin et al 1999(Yerokhin et al , 2000Baszkiewicz et al 2005;Cao 2007).…”

Effect of SiO 3 2− /OH− on plasma electrolytic oxidation of Ti-5Mo-4V-3Al

et al. 2010

Plasma electrolyte oxidation (PEO) was utilized to produce thick films on titanium and Ti-5Mo-4V-3Al alloys by immersing them in various solutions of Na 2 SiO 3 and KOH with different concentrations to investigate the effect of SiO 2 3 -/OH -relations on the morphology and formed phases by utilizing SEM and XRD. Corrosion resistance is evaluated by open circuit potential (OCP) variation of samples in NaCl 3⋅5% and potentiodynamic polarization. The results show that the unstable film is formed by using more aggressive PEO electrolyte. By increasing this ratio, pore size varied from fine to coarse and the rate of corrosion decreased and OCP became more positive. The best protective film was formed in SiO 2 3 -/OH -ratio of 1.
