The quality of titanium cast parts depends not only on the corrosion reaction of the mold in contact with the titanium alloy melt, but also on the dimensional accuracy and the surface quality of the investment casting mold. Usually, the ceramic mold is produced by dip-coating. This contribution investigated the coating properties of green calcium zirconate (CaZrO₃) coatings produced by the replica technique. Thus, the effect of different coating slurries as well as different coating technologies on important coating properties was analyzed. In all cases, centrifuging and spraying produced thinner coatings compared to dip-coating. Using an appropriate coating slip, particularly centrifuging revealed a cohesive homogeneous coating surface and is therefore a promising technology for the production of functional coatings for titanium casting molds.

钛铸件的质量不仅取决于与钛合金熔体接触的模具的腐蚀反应，还取决于熔模铸造模具的尺寸精度和表面质量。通常，陶瓷模具是通过浸涂生产的。这项研究调查了绿色锆酸钙（CaZrO ₃）通过仿制技术生产的涂层。因此，分析了不同涂料浆料和不同涂料技术对重要涂料性能的影响。在所有情况下，与浸涂相比，离心和喷涂产生的涂层都更薄。使用适当的涂层浆，特别是离心分离，可显示出均匀的内聚涂层表面，因此是生产用于钛铸模的功能性涂层的有前途的技术。
