摘要：
Al2O3 coatings were formed on stainless steel substrates by atmospheric plasma spraying using air and hydrogen gasses. The increase of the power increases the mean plasma flow temperature and velocity from 4540 to 5150K and 1460 to 1590m/s, respectively. The effect of torch power on the coating microstructure and phase composition was investigated. The increase of torch power almost has no effect on the elemental composition of Al2O3 coatings. The results indicated that the coating roughness decreased from 5.05 to 3.65 mu m with increased power. The X-ray diffraction measurements indicated that the as-sprayed coatings are composed of -Al2O3, -Al2O3, and -Al2O3 phases. The coating produced at the highest torch power had the highest amount of the -Al2O3 and -Al2O3 phases. Copyright (c) 2015 John Wiley & Sons, Ltd.
