REPORT OF INSPECTION AND PROGRESS IN APPLICATION OF STELLITE 6B OVERLAYS OF HIGH POINT (PC(H)-1)

Abstract

An inspection of the struts, nacelles and foil assemblies of PC(H)-1 showed: (1) damage to coatings of struts, nacelles and foil downstream of forward propellers includes erosion and adhesion separation; (2) damage to strut, nacelle and foils areas downstream of forward propellers and in other areas is caused by static and high velocity corrosion of exposed HY-80; (3) severe erosion damage of sea water inlets in struts had occurred; (4) blistering of the anti-corrosive and anti-fouling coatings (Navy formulas 117, 119 and 121) occurred on the aft foils; (5) the adhesive strength of the polyurethane coating applied to the sea water inlets and areas of the leading edge of the aft foil was low; and (6) the coating on the forward foil and strut assembly, and on areas approximately 15 inches above the aft natelle-strut joint, were in good condition. The fabrication and application of Stellite 6B overlays to areas of the aft struts and foils of Pc(H)-1 were initiated.
