BEND- OVER- SHEAVES FATIGUE TESTING OF 2- INCH- DIAMETER MARINE ROPES
Many marine ropes are zinc-coated for protection against corrosion. However, the "'in-air'' bend-over-sheaves (BOS) fatigue resistance of zinc-coated rope is thought by some to be inferior to that of ~right ropes. Electrolytic zinc coating (Bethanizing) is used to provide heavier coating than available by hot-dipped galvanizing, but the effect of type of coating on the "'in-air"' BOS fatigue resistance of the ropes has not been previously established. The research program report ed here was conducted to compare BOS fatigue resistance of 2-inch-diameter galvanized, Bethanized, and bright wire ropes.
