Fluctuations in the composition of aTiO3-based ceramics can be minimized. Next, apply 2MgO/2Al to the opposite side (back side).
Since it is composed of 2O3 ・5Si02 layer, 2MgO・2
Thermal shock resistance due to the low coefficient of thermal expansion of Al2O3.5Si02 can be added. 2MgO・2 for the middle layer
By continuously changing the composition from AA'2(h ・5Si02 to MgO), the difference in thermal expansion coefficient between both layers can be continuously alleviated, preventing peeling due to thermal shock and improving durability. Thermal spraying method can be applied to the formation of this functionally graded material.
