In this research study, to apply uniform and homogenous nanostructured yttriastabilized zirconia (YSZ) coatings on the Inconel 738LC with MCrAlY bond-coat, the effect of electrophoretic parameters was evaluated. Two different suspensions of 3YSZ nanoparticles were prepared in acetylacetone and acetone separately, using an iodine dispersant. The electrophoretic deposition was conducted by applying voltages of 20 V, 50 V and 80 V for 3 min on MCrAlY coated Inconel 738LC. The coatings were sintered for 120 min at 900°, 1000° and 1100°C temperature. The results revealed that the non-uniform coating included some cracks and cavities as the applied voltage exceeded the optimal amount. The results also depicted that the YSZ coating prepared in acetylacetone medium with 0.4 g/L iodine dispersant, voltage of 50 V, coating time of 3 min, and sintering temperature of 1000°C was a uniform and crack-free structure. Furthermore, the results showed that a continuous alumina layer was formed during oxidation.

在这项研究中，为了在带有 MCrAlY 粘结层的 Inconel 738LC 上应用均匀和同质的纳米结构氧化钇稳定氧化锆 (YSZ) 涂层，评估了电泳参数的影响。使用碘分散剂分别在乙酰丙酮和丙酮中制备两种不同的 3YSZ 纳米颗粒悬浮液。通过在 MCrAlY 涂层的 Inconel 738LC 上施加 20 V、50 V 和 80 V 的电压 3 分钟来进行电泳沉积。涂层在 900°、1000° 和 1100°C 温度下烧结 120 分钟。结果表明，由于施加的电压超过最佳量，不均匀的涂层包括一些裂纹和空腔。结果还描述了在乙酰丙酮介质中用 0.4 g/L 碘分散剂制备的 YSZ 涂层，电压为 50 V，涂层时间为 3 分钟，1000℃烧结温度为均匀无裂纹结构。此外，结果表明在氧化过程中形成了连续的氧化铝层。
