...JE Pickett Delamination is the ultimate failure mechanism of a coating. Delamination times often are closely related to the dose of ultraviolet (UV) radiation reaching the substrate or primer, and this dose is related to the UV absorbing capability of the overlying coating. Organic UV absorbers...

... a hard steel sphere against a specimen in the presence of small abrasive particles. The method has been used to investigate the wear resistance of thin PVD coatings (1 to 5 µm), metallic glass ribbons, and paint films in addition to bulk samples of metals, ceramics, and glasses. The associated theory has...

... vapor diffusion through the film, the transmission rate through any particular film should have a linear relationship to the difference in relative humidity across the film for any fixed temperature condition. This linear relationship can only be true if the coating has no interaction with the water...

...NS Berke; HE Townsend Results of the Deutsches Institut für Normung (DIN) Kesternich sulfur dioxide test (DIN 50018) are compared with those of long-term industrial atmospheric exposure tests of sheet steels coated with zinc, aluminum, and Al-Zn alloy coatings. According to the Kesternich test...

...RA Perkins; ES Wright Uncoated Ta-17W and C129Y alloys and coated Ta-10W, C103, and C129Y alloys have been evaluated for short-time creep behavior at 2600 to 3200°F. The time for creep strains of up to 2 percent has been measured and the results have been used to derive empirical equations...

...EA McKinnon; BI Sandor The fatigue life of nickel-plated copper depends upon the thickness of the nickel coating. Increases in life from 150 to 450 percent were obtained by increasing the thickness of the nickel from 0.0001 to 0.00025 in. (0.00254 to 0.00635 mm). A further increase in thickness...

... pass. This critical load is defined as the weight, in grams, at which the stylus completely removes the film in the contacted area. A number of critical loads for various metallic and dielectric coatings have been established and are being used to control the reliability of optical coatings...
