The demand for producing essential cast parts and the design requirements for superior engineering performance have increased in recent years. Sand cores used in conventional aluminum cast parts are harmful to the environment, which limits their application. Utilizing water-soluble cores in the aluminum casting industry is expected to be an environmentally friendly approach due to recyclability of the salt cores. In this study, water-soluble salt cores were made from chloride- and/or carbonate-containing salts in various amounts. The salts were melted and cast into steel molds to obtain salt cores. The salt cores were subjected to three-point bending tests to determine their mechanical strength, the melting points were determined with thermal analyses, and the water solubility was measured at room temperature and 50 °C. A maximum bending strength of 17.19 MPa, a maximum melting point of 776 °C and a maximum water solubility of 89 g salt/100 ml water were obtained for the samples with compositions of 75% KCl–25% K₂CO₃ and 25% Na₂CO₃–75% K₂CO₃, respectively. Fractographs of the samples used in bending tests were taken by a still camera in macro mode, and from these fractured surfaces, scanning electron microscopy studies were performed. The X-ray diffraction pattern of the sample exhibiting optimal properties (28.3% Na₂CO₃ and 71.7% K₂CO₃) also showed that K₂CO₃, NaKCO₃ and KNaCO₃ phases were present in the structure, as expected. An actual casting process with aluminum die casting of an automotive part was also performed. The diecast aluminum part was subjected to a leak-proof test, and X-ray images were used to check for porosity in the part.

近年来，生产基本铸件的需求和对卓越工程性能的设计要求不断增加。传统铝铸件中使用的砂芯对环境有害，这限制了其应用。由于盐芯的可回收性，在铝铸件行业中使用水溶性芯预计将是一种环境友好的方法。在这项研究中，水溶性盐芯是由各种含量的含氯化物和/或碳酸盐制成的。将盐熔化并浇铸到钢模中以获得盐核。对盐核进行三点弯曲测试，以确定其机械强度，通过热分析确定熔点，并在室温和50°C下测量水溶性。₂ CO ₃和25％Na ₂ CO ₃ –75％K ₂ CO ₃。用宏观模式的静态照相机对弯曲试验中使用的样品的分形仪进行拍摄，并从这些断裂的表面进行扫描电子显微镜研究。表现出最佳性能（28.3％Na ₂ CO ₃和71.7％K ₂ CO ₃）的样品的X射线衍射图还显示出K ₂ CO ₃，NaKCO ₃和KNaCO ₃如预期的那样，结构中存在相。还进行了汽车零件铝压铸的实际铸造工艺。对压铸铝零件进行了防漏测试，并使用X射线图像检查了零件的孔隙率。
