This standard specifies the chemical and physical properties of nano-zirconia agglomerated powder for hot spray-on lining, as well as the physical properties of coatings and the technical conditions for the preparatory process. It is suitable for the production and acceptance of nano-zirconia agglomerated powder, as well as the preparation and acceptance of hot spray-on lining. By clarifying the mass standards and technical requirements of powders and coatings, the standards provide a reliable basis for the preparation of high-performance high-temperature and anti-corrosion coatings, which are widely used in high-tech fields such as aviation and energy.
