Damping in Porcelain Enamel Coatings.
Abstract
Porcelain enamels are extensively used as protective and decorative coatings for metal parts. This report describes a study of the damping capability of these coatings at elevated temperatures. A maximum loss coefficient of .04 was observed for a bending specimen of mean thickness 0.09 inches, with a .0055 inch thick porcelain enamel coating. Experimental data showing the dependence of damping on temperature, coating thickness and frequency is presented. A method for determining the complex elastic modulus of the coating material is discussed. Results from bending and torsion experiments are compared. (Author)
