Item Corrosion-wear of NST 60-Mn steel in Cocoa Mucilage(INSInet Publication, 2006) Umoru, L.E.; Akinola, A.O.; Adeoye, M.O.This paperpresents thereport of an investigationon the effect of differentmicrostructures ofNST-60 Mn steel on its corrosion wear resistance in cocoa mucilage The corrosion wear resistance was investigated under an instrumented pin-on-disc wear test rig. The microstructure of the steel was varied by heat treatment procedures such as water-quenching, austempering, martempering and water-quenching plus tempering at 250oC. A variation of the pH, time of exposure and applied load on the corrosion wear resistance of the heat treated sampleswere evaluated. The results obtained showed that hardness is inversely proportional to the rate of wear of the NST-60 Mn steel. Also, the microstructure of the water-quenched sample exhibited the greatest wear resistance in air, cocoa mucilage of pH3.9 and pH4.2 while the as-received NST 60 Mn steel showed the poorest corrosion wear resistance in the same media.
