A Study on Application of Surfactants in Cemented Carbides Ball Milling

Article Preview

Abstract:

Several surfactants were studied in cemented carbides ball milling in this paper by analyzing cemented carbides mechanical properties and SEM images. Appropriate surfactants used in ball milling were selected to replace commonly used surfactant, stearic acid. Impacts of surfactants on hardness, magnetic force and magnetic saturation were also discussed. Oleic acid and AEO-3 as the better surfactant than stearic acid were selected after experiments. How containing oxygen compound affects the cemented carbide mechanical property cannot be recommended at this stage; further investigations are required.
