Latest Patents

One of Yiwang Bao's latest patents is for a high-strength prestressed composite ceramic and its preparation method. This invention addresses the challenges of enhancing the strength of structural ceramics. It involves determining multiple bondable ceramics to create a composite ceramic with a matrix material and a surface layer material. The matrix material is designed to have sufficient strength and a higher expansion coefficient, while the surface layer material features a lower expansion coefficient and a higher elastic modulus. This balance allows for the formation of compressive stress in the surface layer, significantly improving the bending strength of the composite ceramic. The invention provides a practical solution to the difficulties faced in enhancing the strength of structural ceramics.

Another notable patent by Yiwang Bao is a method and apparatus for testing residual stress in coatings. This method includes obtaining the elastic modulus of both the coating and substrate of a target object, as well as the temperature during the coating preparation. By calculating the coating residual stress using specific formulas, this invention offers a systematic approach to assessing the integrity of coatings.
