Mechanism wear of elastomers with oblique impact of solid particles in the aqueous medium

Abstract

An experimental study made it possible to identify the stages and mechanism of deterioration of a rubber surface in an aqueous medium for conditions of impact with a single solid particle and impact with a hydroabrasive jet. The deterioration has a fatigue character and is divided into two stages: formation of the primary site of deterioration and subsequent fatigue spalling of rubber microfragments by the water flow. Rubber wear in water and air differ significantly in topography and durability. A reduction in the friction coefficient in the aqueous medium leads to a large increase in rubber durability
