In this research, the production process of YSZ powder for thermal spraying by co-precipitation method is presented, which is divided into two main stages. In the first stage, YSZ material is obtained through a series of processes, including preparing a soluble precursor from the salts that make up the YSZ powder based on stoichiometric ratios, hydrolyzing the precursor, filtering the precipitates, drying the precipitates, and calcining them. After various tests and confirmation of the chemical composition, phase composition, and purity of the synthesized YSZ powder, the first stage is completed. In the second stage, the produced powders undergo the granulation process to increase their flowability and thermal sprayability. Following the completion of the second synthetic stage, YSZ powder is ready for use in thermal barrier coatings. The synthesized powder closely resembles the highly regarded Metco 204NS-G powder, known for its superior performance and final coating structure.
