Chitosan biocoatings were successfully deposited on the Ti15Mo alloy surface via cataphoretic deposition from a solution of 1 g dm⁻³ of chitosan in 4% (aq) citric acid. The influence of the cataphoretic deposition parameters on quality and morphology of the obtained coatings were investigated using fluorescence and scanning electron microscopy. The functional groups' presence in chitosan chine were confirmed by ATR-FTIR methods. X-ray analysis revealed the amorphous structure of the chitosan coatings on the Ti15Mo alloy surface. The conducted studies also include assessing the abrasion resistance and adhesion to the substrate of the obtained chitosan coatings. The results show that utilizing the citric acid as a solvent results in the formation of pore free coatings. The yield of the electrophoretic deposition process was in the range of 2–10 mg of deposited chitosan per 1 cm². The obtained coatings through the unique properties of chitosan are a promising biomaterial for application in medicine.

柠檬酸溶液在 Ti15Mo 生物医学合金上电泳沉积壳聚糖涂层

通过电泳沉积从 1 g dm ^-3溶液中成功地将壳聚糖生物涂层沉积在 Ti15Mo 合金表面壳聚糖在 4% (aq) 柠檬酸中。使用荧光和扫描电子显微镜研究了电泳沉积参数对所获得涂层的质量和形态的影响。通过ATR-FTIR方法证实了壳聚糖中官能团的存在。X 射线分析揭示了 Ti15Mo 合金表面壳聚糖涂层的非晶结构。所进行的研究还包括评估所获得的壳聚糖涂层的耐磨性和对基材的粘附性。结果表明，使用柠檬酸作为溶剂导致形成无孔涂层。电泳沉积过程的产量在每 1 cm ^{2沉积壳聚糖 2-10 mg 的范围内}. 通过壳聚糖的独特性能获得的涂层是一种很有前途的医学应用生物材料。
