Abstract

Here, noble metal Pd-doped Y3Al5O12 thermal barrier coatings (TBCs) were efficaciously prepared by means of cathode plasma electrolytic deposition (CPED). The formation mechanism of the Y3Al5O12 coatings and the difference in coating performance before and after doping with Pd were analyzed. The results indicated that the preparation of the Y3Al5O12 TBCs by using the CPED method could be divided into three stages, and the phase compositions of the coatings obtained with different deposition times were different. A single-phase Y3Al5O12 TBCs with a 115-μm thickness was obtained after a deposition time of 20 min. After Pd doping, the average surface roughness of the TBCs decreased from 27.72 to 13.84 μm, and the high-temperature oxidation resistance and thermal shock resistance at 1050 °C improved significantly.
