Electrophoretic deposition of the titanium nitride (TiN) coatings from suspensions prepared by dispersion of TiN particles in triethanolamine (TEA) containing butanol medium was studied. Effects of the TiN particles concentration (CTiN) on the weight of the deposited coatings, triethanolamine concentration (CTEA=0.25, 0.5, 0.75, and 1 mL/L) on the Zeta potential of the TiN particles, suspension electrical conductivity and pH, as well as effects of the deposition voltage (Vd=60, 90, and 120 V) and time (td =1, 2, and 3 minutes) on the microstructure and thickness of the deposited coatings were investigated. Variations in deposition current density, effective deposition voltage, electrical resistance, and deposited coating weight versus deposition time were recorded. The morphology of the as‐dried coatings was studied using Scanning Electron Microscope (SEM). The results indicated that by increasing the CTiN the weight of deposits increases linearly up to 40 g/L. For suspensions containing CTiN=40 g/L, the optimum CTEA is obtained to be 0.5 mL/L leading to Zeta potential of 43.25 mV. Uniform and crack‐free as‐dried coatings obtained at Vd and td of 90 V and 2 minutes, respectively.

电泳沉积氮化钛涂层

研究了通过将TiN颗粒分散在含丁醇的三乙醇胺(TEA)中制备的悬浮液中电泳沉积氮化钛(TiN)涂层的方法。TiN颗粒浓度(C T iN)对沉积涂层重量的影响,三乙醇胺浓度(C TEA = 0.25、0.5、0.75和1 mL / L)对TiN颗粒的Zeta电位,悬浮液电导率和pH值,以及沉积电压(V d = 60、90和120 V)和时间(t d分别在1分钟,2分钟和3分钟)上研究了沉积涂层的微观结构和厚度。记录沉积电流密度,有效沉积电压,电阻和沉积涂层重量相对于沉积时间的变化。使用扫描电子显微镜(SEM)研究了干燥涂层的形貌。结果表明,通过增加C T iN,沉积物的重量线性增加至40 g / L。对于含有C T iN = 40 g / L的悬浮液,获得的最佳C TEA为0.5 mL / L,导致Zeta电位为43.25 mV。在V dt d获得均匀且无裂纹的干燥涂层 分别为90 V和2分钟。
