Standards Development
This standard specifies the hardness test method for fine ceramics in a high-temperature oxidation environment. This method can also be used to determine the hardness of metallic materials, ceramic matrix composites, and other materials in a high-temperature oxidation environment.
Due to their excellent stability in high-temperature oxidation environments, ceramic materials are increasingly widely used in such environments, such as kilns, experimental furnaces, aero-engine blades, and satellite surfaces. The hardness of ceramics in high-temperature oxidation environments can easily evaluate the quality and reliability of ceramics. However, a suitable method for determining the hardness of ceramics in high-temperature oxidation environments has not yet been established. Accurately measuring the hardness of ceramics in high-temperature oxidation environments is crucial. This document aims to develop a simple and practical method for measuring the hardness of ceramics in high-temperature oxidation environments. This standard is applicable to the determination of the hardness of fine ceramics under high-temperature conditions. This method can also be used for quality control, characterization, and generation of design data of superalloys and ultra-high temperature ceramic matrix composites, etc.
