Abstract

This research is to investigate the possibility of the organic molybdenum compounds as the EP additive for the metal forming processes instead of MoS₂ that is widely employed. A series of experiments was carried out using a strip-ironing type and a rolling type tribometer to investigate the lubricating effect of MoDTP in the metal forming process. Experiments using aluminum alloy A 5 N 01 showed that MoDTP in the lubricity is inferior slightly to MoS₂ at low working speed but even more excellent than MoS₂ at high working speed. XPS spectra of worked surfaces showed that MoS₂ can’t be found at worked surface under MoDTP lubrication. It was concluded that the excellent lubricity of MoDTP is not due to the creation of MoS₂ during deformation process.
