title = "Preparation, characterization of (La0.9Ca0.1)(Cr0.9Mg0.1)O3 high emissivity coatings deposited by APS",
abstract = "Solid state synthesis was employed to prepare ceramic powders. The (La0.9Ca0.1)(Cr0.9Mg0.1)O3 coatings were deposited by APS equipment on GH98 Super-alloy substrate. The Mg and Ca atoms entered the lattice of LaCrO3 crystal to form (La0.9Ca0.1)(Cr0.1Mg0.1)O3 but did not change the orthorhombic perovskite structure. The coatings are composed of splats, pores and micro cracks. The average porosity of (La0.9Ca0.1)(Cr0.9Mg0.1)O3 coating is 12.4\% and the average bond strength is 28.3Mpa.The (La0.9Ca0.1)(Cr0.9Mg0.1)O3 powders did not occur phase transition during heated process in high temperature plasma plume. No impurity is introduced in the coating during plasma spraying process. Due to the significant distortion of (La0.9Ca0.1)(Cr0.9Mg0.1)O3 lattice, the normal total emissivity of (La0.9Ca0.1)(Cr0.9Mg0.1)O3 coatings are 0.88 at 600°C and 0.89 at 800°C. The crystal structure is stable in the temperature range of thermal shock test from room temperature to 1100BC. And no spalling or fracture occurred within 10 times thermal shock which means the coatings could withstand the impact of thermal stress.",
