Experimental Evaluation of the Influence of Mechanical Properties of Contacting Materials on Gas Abrasive Wear of Steels in Sandblasting Systems

Abstract

This article discusses the influence of the mechanical properties of contacting materials on gas abrasive wear of steels in sandblasting devices. Wear rates of some structural, alloyed, and special steels have been determined. The ratios of mechanical properties to wear rates during processing by quartz sand and corundum have been compared. It has been discovered that most of the considered parameters (yield strength, ultimate tensile strength, relative elongation at failure, specific fracture work at failure, and impact toughness) are not characterized by correlation between variation of wear rates and variation of the mechanical properties of the considered steels. The only unique interrelation is observed for wear rates as a function of resilience.
