Erosion efficiency-a new parameter to characterize the dominant erosion micromechanism

Tribo-performance analysis of red mud filled glass-epoxy composites using Taguchi experimental design

“…Therefore, a large number of factors are included so that non-significant variables can be identified at earliest opportunity. Exhaustive literature review on erosion behaviour of polymer composites reveal that parameters viz., impact velocity, filler content, erodent temperature, impingement angle, stand-off distance and erodent size etc largely influence the erosion rate of polymer composites [8,11,17]. The impact of six such parameters are studied using L 27 (3 13 ) orthogonal design.…”

“…In the case of a stream of particles impacting a surface normally (i.e. at a = 90°), erosion efficiency (g normal ) defined by Sundararajan et al [17] is given as…”

Investigation on solid particle erosion behaviour of polyetherimide and its composites

“…It has been reported [29,35] that the parameter called as erosion efficiency (η), can be used for identifying the brittle and ductile erosion response of various materials to solid particle erosion. The erosion efficiency (η) can be obtained from the following equation:…”

Erosion Wear of Ductile Materials: A Review

“…The second stage is due to the breaking up of impacting particles so that fragments are projected radially from the point of impact and produce secondary damage as shown in fig (1).…”

“…erosion rate and erosion efficiency, which are frequently used during the study of erosion wear models. The concept of erosion efficiency is given by G. Sundarrajan (1). The dimensionless erosion rate (E) is defined as the ratio of mass loss suffered by erodent surface to the mass of erodent particle causing the mass loss.…”
