Evaluation of Alternate F-14 Wing Lug Coating
Abstract
The F-14 wing lug is coated with specific formulation polyurethane coating which prevents scoring of the wing lug by providing a wear surface for the outside diameter of the wing pivot bearing. The manufacture of this coating material was discontinued in 1991 because the original formulation used talcs which contained asbestos as impurities. The new formulation, containing asbestos free talcs, was inadequate in providing the abrasion resistance required to protect the F-14 wing lug. A new coating or coating process was required. A centrifugation processing procedure for the new formulation was developed which appeared to provide a coating that exhibited similar wear characteristics as the original coating. Oscillation wear tests were required to determine bearing wear performance of the alternate coating under normal and high stress in both the dry and fluid contaminated states.
