This paper reports on the surface modification of a Ti-15Mo alloy by plasma electrolytic oxidation (PEO). This process was carried out in solutions of 0.1M Ca(H2PO2)2 with various concentrations of tricalcium phosphate (Ca3(PO4)2), wollastonite (CaSiO3), or silica (SiO2) using voltages of up to 350V. The surface microstructure (SEM, cross-section of coating), roughness and chemical composition (energy-dispersive X-ray spectroscopy, thin layer X-ray diffraction, X-ray photoelectron spectroscopy and Raman spectroscopy) of the porous oxide layers were investigated. The concentration of powder added to the solution changed the chemical composition and morphology of PEO coatings on the Ti-15Mo alloy surface. Calcium and phosphorous compounds were detected in the coatings formed on the substrate by the PEO process at 300V.
本文报道了通过等离子体电解氧化（PEO）对Ti-15Mo合金进行表面改性的研究。该过程在含有不同浓度磷酸三钙（Ca3(PO4)2）、硅灰石（CaSiO3）或二氧化硅（SiO2）的0.1M次磷酸钙（Ca(H2PO2)2）溶液中进行，使用高达350V的电压。研究了多孔氧化层的表面微观结构（扫描电子显微镜，涂层横截面）、粗糙度和化学成分（能量色散X射线光谱、薄层X射线衍射、X射线光电子能谱和拉曼光谱）。添加到溶液中的粉末浓度改变了Ti-15Mo合金表面PEO涂层的化学成分和形态。在300V下通过PEO工艺在基底上形成的涂层中检测到了钙和磷化合物。
