“…As expected, the specific erosion rate increased with increasing particle kinetic energy on the target. The resulting velocity exponents were in the range of 2-4, consistent with those reported by Feng and Ball [37] for solid particle erosion of ductile materials obtained using various erodent particles. …”

“…For example, Feng and Ball [17], using silica sand erodent of sizes 631000 mm impacting a stainless steel target, observed that the value of particle size exponent was 3 AE 0.1. Whereas most authors agree that particle impact velocity has a significant effect on the erosion rate [15,17,19], values of velocity exponent reported in the literature vary between 1.1 and 3.4 depending on target material and impingement angle [17]. Dependence of erosion rate on the impact angle (between the target surface and the erodent trajectory) is largely determined by the nature of the target material.…”

The estimation of energy dissipation during particle impact is a key aspect in evaluating the abrasive potential of impact process. Whereas numerous numerical and analytical approaches exist, aimed at explaining observed wear phenomena, few researchers have attempted to measure the energy dissipation during impact. This article reports the results of systematic acoustic emission (AE) energy measurements aimed at detecting the amount of energy dissipated in a carbon steel target during airborne particle impact. Three experimental arrangements were used to investigate three impact regimes; low velocitylow mass (impact speeds of 12.5 m/s and masses of 4.9 Â 10 À6 to 2.3 Â 10 À4 g), low velocityhigh mass (sphere masses of 0.0012 g), and high velocitylow mass (impact speeds of 416 m/s). Within each of these regimes, both single-particle and multiple-particle impacts were studied in order to investigate the effect of overlapping events. Two parameters, particle diameter and particle impact speed, both of which affect the energy dissipated into the material were investigated and correlated with AE energy. The results show that AE increases with the third power of particle diameter, i.e. the mass, and with the second power of the velocity, as would be expected. The diameter exponent was only valid up to particle sizes of around 1.5 mm, an observation which was attributed to different energy dissipation mechanisms with the higher associated momentum. The velocity exponent, and the general level of the energy were lower for multiple impacts than for single impacts, and this was attributed to particle interactions in the guide tube and/or near the surface leading to an underestimate of the actual impact velocity in magnitude and direction.

“…The sands have a range size of 0.15-0.3 mm with particle shapes varying from spherical to angular which is peculiar to most eroding sand particles. The hardness and fracture toughness determination was based on the literature values given by some authors [18][19][20][21][22] as stated by [4] in the …”

In order to assess the extent of sandstorms effect on automobile glass in the area mostly prone to sandstorms phenomena typical of the Northern part of Nigeria, sandblasting tests were conducted in laboratory on a laminated soda lime glass of 300mm x 300mm with standard automobile glass thickness of 4mm each and PVB film of 1 mm. The sand particles were projected by sandblasting machine with an air flow speed of 54km/hr (15m/s) and the impact angle was fixed at 90 0 while the blasting duration and distance of impingement was 60secs, 180secs, 300secs and 60cm, 40cm, and 20cm respectively. The erosion tests carried out show significant drop in impact strength, and flexural strength.
