THE EFFECTS OF COATINGS APPLIED TO CONTACT SURFACES OF HIGH STRENGTH BOLTED JOINTS ON SLIP BEHAVIOR AND STRENGTH OF JOINTS
The research objective was to determine if certain rust inhibiting coatings applied on contact surfaces of friction-type high-strength bolted structural joints could provide sufficient slip resistance under constant or cyclic loads. The performance of various coatings, including a vinyl wash primer, an organic zinc-rich primer and zinc metal applied by hot-dip galvanizing, were evaluated using results of tensile, creep, and cyclic tests on double shear butt spliced specimens. Important parameters considered in the testing program were coating type, hardness and thickness, clamping bolt tension, and method of loading.
