TEST METHODS FOR MAGNESIUM SURFACE TREATMENTS. Period Covered: February 1, 1955 to July 1, 1956
Abstract
A study was made of test methods whereby the quality of Mg sunface treatments could be determined. Methods which measured the corrosion-inhibiting powcr of the coating were found unsatisfactory. A method based on measurement of paint adherence after exposure to a corrosive environment was found quite promising. The latter approach evolved the Gauze-Peel Test,'' in which a gauze strip is embedded in the orgainic coating. After exposure to accelerated corrosion, the gauze is peeled from the surface. Both quantitativc (peel strength) and qualitative (visual examination of the stripped area) evaluations are easily made. An important observation made during preparation of experimental specimens was that contact between Mg and steel during Dow 7 treatment leads to rapidly deteriorating painted surfaces. (auth)
