Abstract:Effect of the metalloid element B on the glass forming ability and thermal stability for electroless plating Fe-Mo-B alloy deposits has been studied by X-ray diffraction analysis and differential scanning calorimetry, which is analized by structure chemistry theory. The glass forming and thermal stability could be improved by adding element Mo. It has been found that the range of amorphous formation is 6.6%~24.5%B, 11.3%~16.9% Mo and 57.4%~73.6% Fe for the Fe-Mo-B alloy deposits, which is larger than that for the electroless plating Fe-B alloy deposits. The experimental results have been analyzed and discussed by the empirical criteria of the glass forming ability and thermal stability.
