Thermal shock resistance evaluation method and evaluation device

摘要

PURPOSE: A thermal shock resistance test method and automated test equipment are provided to test the thermal shock resistance of a base material with detecting a crack formed by a thermal shock when being rapidly cooled. CONSTITUTION: A thermal shock resistance test method comprises the following steps. Thermal shock resistance test equipment accepts a base material to be tested in an internal space of the equipment. An exothermic material is filled in the internal space(S100). The exothermic materials is lit and The base material is heated up by combusting the exothermic material(S200). The base material is cooled(S300). The thermal shock resistance of the base material is evaluated by detecting a crack created in the base material(S400). The exothermic material emits heat at the temperature higher than 2000C with the magnetoelectricity reaction of combustion. The exothermic material is a mixture made of one among SiO2 and Si and one among C and Mg.
