Abstract:

The shearing force required for breakaway of a 12 x 12 inch 7075-T6 aluminum alloy plate supported by two of its edges by the flanges of 1 x 1 inch 7075-T6 aluminum alloy angles and separated from them with anti-freeze lubricants was used to estimate the seizure characteristics of the various lubricants. During test, a block of solid carbon dioxide was placed on the 12 x 12 inch plate to induce a low temperature at the sliding surfaces. The lubricants tested were water, glycerol, petrolatum, Dow Corning DC silicone oil, n-hexanol and ethyl propionate. The breakaway forces for each lubricant were as follows water, 45.0 lb. glycerol, tin film, 43.2 lb. glycerol, thin film, 43.2 lb. thick film, 15.8 lb. petrolatum, thin film, 13.1 lb. petrolatum, thick film, 32.3 lb. DC-4 silicone oil, thick film, 6.6 lb. n-hexanol, 17.6 lb. and ethyl propionate, 18.0 lb. Author
