A Y(2)O(3)-modified chromizing coating was produced by chromizing an as-electrodeposited Ni-Y(2)O(3) composite film using pack cementation method at 1 100 degrees C for 3 h. For comparison, chromizing was also performed under the same condition on an as-deposited Ni film without Y(2)O(3) particles. Oxidation at 900 degrees C for 120 h indicates that although on both two chromizing coatings chromia scales grow during oxidation, the Y(2)O(3)-modified chromizing coating exhibits an increased oxidation resistance due to the formation of thinner, denser and finer-grain scale. The effect Of Y(2)O(3) on the coating formation and the coating oxidation behavior was discussed in detail.
