The Effects of Two Anti-Corrosion Processing Mode on the against Slip Coefficient between Friction Surface of High-Strength Bolts Connection

Both hot-dip coating and zinc-rich coating can improve the longevity of the steels, but the coarseness of the steels covered the different coating will be different. The steels with the two coatings, a sort of hot-dip high-strength bolts connection were used to study the against slip coefficient between frictions. The results show that a higher against slip coefficient between frictions of high-strength bolts connection with zinc-rich coating was obtained. When MoS2was used on the hot-dip high-strength bolts, the standard deviation of the torque coefficient of the bolt connection pairs was decreased and a highest against slip coefficient between frictions was obtained.
