Salt Water Resistance of Surface-Compression Strengthened Glass

Abstract

Three types of ion-exchange surface-compression strengthened (SCS) glass, with ultimate flexural strengths of 38,000 to 66,800 psi, were abraded and maintained in circulating salt water for periods up to three years under constant flexure at stress levels of 60-70% of their ultimate strengths. Tempered Pyrex with strength of 11,700 psi also was abraded and maintained for like periods at the 50% stress level in salt water. The important effect of time under stress and salt water was to make SCS glass stronger. Surface-compression strengthened glass is attractive for use as a naval structural material.
