Abstract The structure of alpha + beta-titanium alloy, its microhardness, surface roughness, and wear and corrosion resistance after anode plasma electrolytic borocarburising (PEB/C) in electrolyte containing boric acid, glycerol and ammonium chloride were investigated. An X-ray diffractometer and scanning electron microscopy were used to characterize the phase composition and structure of the modified surface. Tribological properties of treated titanium alloy were evaluated using a ball-on-disc tribometer under dry testing conditions. The effect of electrolyte compositions on corrosion resistance of the PEB/C samples was examined by means of potentiodynamic polarization in Ringer's solution. It was shown that the electrolyte containing boric acid, glycerol and ammonium chloride provided the saturation of alloy with boron, carbon and oxygen and formation of TiO2 with rutile structure and boron/carbon solid solution in titanium. The anode PEB/C resulted in a decrease in surface roughness by 2.5 times, corrosion current density by 9 times, wear rate by 54 times and an increase in microhardness to 1075 HV10.

α+β-钛合金阳极等离子电解硼碳共渗

摘要 研究了在含硼酸、甘油和氯化铵的电解液中阳极等离子电解硼渗碳（PEB/C）处理后的α+β-钛合金的结构、显微硬度、表面粗糙度以及耐磨和耐腐蚀性能。X射线衍射仪和扫描电子显微镜用于表征改性表面的相组成和结构。在干燥测试条件下使用球盘摩擦计评估处理后的钛合金的摩擦学性能。电解液成分对 PEB/C 样品耐腐蚀性的影响通过林格溶液中的动电位极化来检验。结果表明，含硼酸、甘油和氯化铵的电解液提供了含硼合金的饱和度，碳和氧以及在钛中形成具有金红石结构和硼/碳固溶体的 TiO2。阳极 PEB/C 导致表面粗糙度降低 2.5 倍，腐蚀电流密度降低 9 倍，磨损率提高 54 倍，显微硬度增加至 1075 HV10。
