Abstract

Recently, considerable emphasis has been placed on the processing of low-grade ore minerals through thermal spray techniques. In the present investigation, the suitability of detonation spray system for coating fly ash onto a mild steel substrate has been demonstrated. Resultant coatings are 2-3 times harder than the substrate material and also exhibit a 3-fold reduction in coefficient of friction under sliding wear conditions. However, these coatings exhibit poor sliding wear resistance.
