Nanostructured Bearing Alloy Studies.

Abstract

This period marks the transition in the powder making from the Co-Reduction method to the Thermal Decomposition. The latter method was studied earlier in this program and was dropped in favor the Co-Reduction method because of the better chemical homogeneity in powder produced by the Co-Reduction method. The main drawbacks for the Co-Reduction methods for making M50 powder are the high cost of the chemical precursors and the lengthy vacuum sublimation needed to remove the deleterious chloride by-products in the powder. Thermal Decompositon method which does not have these problems was therefore revisited recently with the goal of improving its homogeneity. It was found that the homogeneity of the Thermally Decomposed powder can be enhanced significantly by high-energy ball mixing method.
