Quantitative abrasion resistance of optical coatings and surfaces

Abstract

Two-silane chemical vapor deposition treatment of polymer (nylon) and oxide surfaces that yields hydrophobic (and superhydrophobic), abrasion-resistant thin films A m~el for understanding the abrasion of a surface by falling abrasive is developed and tested expenmental1y. A quantitative measure of abrasion resistance, useful for characterizing optical surface~ and. hard ~oatings, appears naturally in the theoretical model and experimental data. Numencal sImulatIons reproduce both the model and the experimental data.

Normal impact of sand particles with solar panel glass surfaces

“…Ludwig and Stoner carried out a quantitative study on the abrasion resistance of surfaces in optical devices by falling abrasive sand. They have also provided empirical models for understanding the abrasion phenomenon using their experimental results [17]. Bousbaa et al [18] investigated the effect of sandblasting duration on the mechanical properties as well as the optical performance of glass in a sandblast simulator.…”

Study of light scattering on a soda lime glass eroded by sandblasting

“…These tendencies are in good concordance with those reported in literature on various types of brittle materials and under various tests conditions. 8,9 The windshields degradation by sand or dust particles can lead to serious problems for drivers. In operational use, the windshield glass may encounter multiple high velocity impacts with solid particles, usually silica.…”

Effect of water on the transmittance of glass plates with eroded surfaces

“…The sand was allowed to freely fall from a fixed height. [7][8][9] The sand particles damaged the surface of glass by creating microcracks.…”
