Chitosan biocoatings were successfully deposited on the Ti15Mo alloy surface cataphoretic deposition from a solution of 1 g dm 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 cm. The obtained coatings through the unique properties of chitosan are a promising biomaterial for application in medicine.
壳聚糖生物涂层通过在4%（水溶液）柠檬酸中1 g/dm³壳聚糖溶液的电泳沉积成功地沉积在Ti15Mo合金表面。使用荧光和扫描电子显微镜研究了电泳沉积参数对所得涂层质量和形态的影响。通过ATR-FTIR方法确认了壳聚糖链中官能团的存在。X射线分析揭示了Ti15Mo合金表面壳聚糖涂层的无定形结构。所进行的研究还包括评估所得壳聚糖涂层的耐磨性和与基材的附着力。结果表明，使用柠檬酸作为溶剂会形成无孔涂层。电泳沉积过程的产率为每1平方厘米沉积2-10毫克壳聚糖。通过壳聚糖的独特性能获得的涂层是一种有前途的生物材料，可应用于医学领域。
