Thermal shock resistance of ceramics materials.

Melting of ceramics at high temperature involve a thermal shock during cooling and this will require a high temperature preheating of the powder bed to prevent thermal shock from the cooling of the melt pool from high temperature to lower temperatures. The thermal shock of ceramic materials is influenced by many factors such as strength young s modulus fracture toughness. Ceramic materials have a very high melting point and are less resistant to thermal shock. Development of thermal shock tolerant material with hydrophobic surface aip advances 2018.

Thermal shock is one of the main drawbacks in the utilization of ceramics for high temperature applications and one of the aims of making cmcs is to improve thermal shock resistance. These temperature fluctuations cause thermal stresses in the ceramic and consequently the propagation of micro cracks that permanently damage the material. On the basis of the strain energy concept in the latter half of this paper a new thermal shock test method for refractory firebricks is introduced. Thermal shock resistance refers to a material s ability to withstand rapid changes in temperature.
