| Abstract: | In order to optimize the processing parameters of nanostructured coating prepared by plasma spraying,the change of nanoparticle size during plasma spraying was investigated.Based on the Brook's classical theory about grain growth,a computational model for analyzing the nanoparticles growth of plasma-sprayed nanostructured agglomerated ZrO2-7%Y2O3 powders was established.The effects of the thermal circulation curve and nanoparticle diameter on grain growth were studied.Meanwhile,experiment of plasma spraying... |
| Keywords: | plasma spraying nanostructured agglomerated powders nanoparticles growth |
