Thermal Barrier Coating

Material Introduction


The thermal barrier coating is an yttria-stabilized zirconia (YSZ) ceramic coating prepared by atmospheric plasma spraying technology. This can withstand high temperatures, oxidation, and thermal shock, during its service life, playing an important heat insulation role for the base material.This means components made of the base material can be used at high temperatures and improve the thermal efficiency of the whole machine.
