Study on the three body abrasive wear behaviour of EN8-steel before and after coating of wear resistance material

Abstract

The effects of aluminum, zirconium, and fly-ash mixture additions on three-body abrasive wear behaviour of EN8- steel have been systematically investigated using a threebody abrasive machine and SiO<sub>2</sub> as abrasive.The coating material is preferred by using 49% aluminum and 49% zirconium is mixed by using 2% fly-ash, the fly ash works as a binder between aluminum and zirconium. Investigate the worn surface of EN8-steel specimen before and after coating of Al<sub>2</sub>O<sub>3</sub>, ZrSiO<sub>4</sub> and fly-ash mixture. The Al<sub>2</sub>O<sub>3</sub>, ZrSiO<sub>4</sub> and fly-ash coated working specimen will give less wear rate in grams compared to working specimen without coating. It clearly shows that using Al<sub>2</sub>O<sub>3</sub> and ZrSiO<sub>4</sub> will reduce the wear rate and increase life of EN8 steel.
