James, George T. (1955) The effect of adhesive coating on the fatigue properties of 2014-T and 7075-T at normal and elevated temperatures. Engineer's thesis, California Institute of Technology. http://resolver.caltech.edu/CaltechETD:etd-01062004-163541
A problem of current practical interest to the field of Aeronautics is whether cement coatings associated with strain gages and fatigue warning indicators have appreciable effect upon fatigue characteristics.
Fatigue tests in rotary bending were conducted at room temperature, 200[degrees]F and 400[degrees]F on plain specimens of 2014-T and 7075-T and specimens coated with a synthetic resin lacquer, a synthetic resin cement, and an epoxy resin cement.
The effect of these coatings was slight at room temperature, falling within the scatter band, but apparently affording a small increase in fatigue life. At 200[degrees]F there was no definite effect, but at 400[degrees]F there was a pronounced lowering of fatigue life for all the coated specimens. Parallel results were obtained in 2014-T and 7075-T.
