Thermal shock is the name given to extreme temperature difference (gradient) across an object, which can result in cracking and/or breaking. Glass and ceramic objects are particularly vulnerable to this form of failure, due to their low toughness and low thermal conductivity. However, they are used in many high temperature applications due to their high melting point.
Thermal shock occurs when a thermal gradient causes different parts of an object to expand by different amounts.
This differential expansion can be understood in terms of stress&nbs******bsp;of strain, equivalently. At some point, this stress can exceed the strength of the material, causing a
crack to form. If nothing stops this crack from propagating through the material, it will cause the object's structure to fail.

This situation is similar to non-continuously being low temperature&nbs******bsp;high temperature; thermal shock tester can make various products accomplish test in shortest time. Chemical change&nbs******bsp;physical
injury made by heat shock is caused by thermal expansion and contraction change&nbs******bsp;other physical nature change; use TST system to achieve entire trust for various
products. Effect of heat shock is including finished products cracked&nbs******bsp;broken layer, and electrochemical change caused by replacement. All-digital automatic control of TST system makes you easy and handy operation.
