HIGH TEMPERATURE SOLID DRY FILM LUBRICANTS. Period covered : January 1, 1958 to December 31, 1958

Technical Report ·
OSTI ID:4203302
Chemical stability and coefficient of friction have been determined for selected materials. Changes in weight, color, and physical appearance were noted when heated to 1000 deg F in air. A special pellet friction machine was used to determine coefficients of friction at these temperatures while under light loads. Silicon dioxide films have been prepared with and without solid lubricants from a hydrolyzed tetraethyl onthosilicate solution. Similar films were prepared using boric oxide; low coefficients of friction and reasonable wear-lives were obtained. Samples of five comcommercial lubricants were irradiated at levels up to 10/sup 9/ roentgens (gamma) and 3 x 10/sup 16/ NVT (neutron). Wear-life tests on the irradiated samples, although not conclusive, indicate that the radiation has little permanent effect on the lubricative properties of the films. (auth)
