 Effects of Surface Properties of Brown Fused Alumina on the Strength of Vitrified Abrasive Tools


Brown fused alumina is one of the most common abrasive grit used in vitrified abrasive tools. The using of natural raw materials in production will eventually result in impurities, such as Fe, Ca, Ti, Mg. Brown Fused Alumina abrasive grains will react with bond under high temperature, resulting in the apparent cracks, pores and crystal forming on the reaction interface of abrasive grain and bond, and consequently the strength of abrasive grinding wheels is reduced.

If the surface of brown fused alumina abrasive grains are property treated by acid cleaning, coating or high temperature roasted, the strength of vitrified abrasive tools will be enhance.
