摘要：

A Y2O3-modified chromizing coating was produced by chromizing an as-electrodeposited Ni-Y2O3 composite film using pack cementation method at 1 100 ℃ 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 ℃ 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.
