摘要：
The effects of oxygen partial pressure (pO(2)) Of the preoxidation atmosphere on the growth of thermally grown oxide (TGO) and thermal cycle life of plasma-sprayed thermal barrier coatings (TBCs) were investigated. The pO(2) of the preoxidation atmosphere was controlled by using a solidstate electrochemical oxygen pump system. The purity and microstructure of continuous Al2O3 layer formed on the bond coat during preoxidation at 1050 degrees C were highly influenced by the pO(2) of the atmosphere. The specimen preoxidized at 1050 degrees C under a pO(2) of 10(-14) to 10(-15) atm, which is around the dissolution pressure of (Co, Ni)(Al, Cr)(2)O-4 spinel, showed the lowest growth rate of TGO and the longest thermal cycle life.
