文摘
The tribological response of bolted joints under different conditions was investigated experimentally. Design of Experiment tools were used to determine the effects of screw surface coating and lubrication. Zinc-coated screws exhibit a lower friction coefficient with respect to black oxidized ones. Ceramic paste lubrication, even when performed at the underhead only, is more effective than oil lubrication. Ceramic paste lubrication in the threads retains a minor importance and is almost ineffective.
