Abstract
A Y2O3-modified chromizing coating was produced by chromizing an as-electrodeposited Ni-Y2O3 composite film using pack cementation method at 1 100 °C for 3 h. For comparison, chromizing was also performed under the same condition on an as- deposited Ni film without Y2O3 particles. Oxidation at 900 °C for 120 h indicates that although on both two chromizing coatings chromia scales grow during oxidation, the Y2O3-modified chromizing coating exhibits an increased oxidation resistance due to the formation of thinner, denser and finer-grain scale. The effect of Y2O3 on the coating formation and the coating oxidation behavior was discussed in detail.
