Mechanical and physical properties of zirconia ceramic materials

Usually, the mechanical properties of materials refer to strength, plasticity, and rigidity. The physical properties of materials include electrical, magnetic, thermal, and chemical behaviors.

The higher the strength and hardness of the ceramic material, the greater the cutting force, the higher the cutting temperature, and the faster tool wear, so its machinability is poor. The higher the modulus of elasticity and toughness, the better the processability of the material. The material’s thermal conductivity, electrical conductivity, thermal expansion coefficient, and other parameters will also have an impact on the different processing technologies of the material.

Composition and distribution of zirconia functional ceramic materials

Different components of the material and different phases of the same component have different resistance to deformation and fracture due to the difference in the microstructure. In addition, for processable nanocomposites prepared by using weak grain boundary phases, the distribution of grain boundary phases is very important to the processing quality and processing efficiency of the material.

Microstructure of Zirconia Functional Ceramic Material

The various damage forms of materials in the machining process such as grinding, such as twins, slippage, and microcracks within the crystal grains, are mainly determined by the physical and thermodynamic properties of the ceramic material itself, that is, it depends on the material formulation And microstructure.

Zirconia functional ceramic material processing process

Experiments show that the grinding performance of ceramic materials not only depends on the composition and microstructure (material characteristics) of the material itself, but also changes with the changes in the grinding process parameters and the type of grinding fluid.

Focusing on improving the surface integrity and T precision of ceramic materials after processing, and reducing surface microcracks and other defects, many scientific researchers have carried out a lot of process optimization work, mainly focusing on: ceramic material cutting and grinding mechanism research; new cutting, Development, and application of grinding tools and grinding wheels; selection of cutting and grinding fluids; selection of reasonable machining parameters (cutting, grinding speed, feed wall, etc.).
