Effect of Environment on Friction and Wear Between Quartz and Steel

The Bureau of Mines conducted experiments to measure the influence of environment on the friction and wear of a steel-quartz system at several speeds and loads. In each test a quartz block was pressed against a rotating ring of low-carbon steel. Environments used were moist air, dry air, dry nitrogen, water, aqueous oleylammonium acetate, and aqueous alouminum chloride.
