Influence of Sustainable Lubrication on the Tribological Behaviour of Phosphorus Bronze
摘要
In this present work, experimental analysis has been carried out in tribological tests of phosphorus bronze with or without lubricating conditions. The industrial lubrication market is seeing a surge in the usage of vegetable oil-based lubricants and bio-lubricants due to its high tribological performance, minimum environmental effect, sustainability, renewability, and biodegradability. A Pin-on-disc tribometer has been used to process the entire experiment and using Scanning Electron Microscope (SEM), to determine the surface texture of the material used during this experiment. It has been performed in both dry and lubricating conditions by varying the applied load from 20 to 40 N and rotating the disc speed varying between 50 to 90 rpm. Also, the track diameter varied from 50 to 80 mm. In the dry sliding condition, the coefficient of friction increased with increasing applied load and sliding speed. A low coefficient of friction is observed at the 20 N load and 50 rpm sliding speed. In the lubricating condition, the minimum coefficient of friction is found in the ethanol lubricating condition in all cases. In the mustard oil lubricating state, the wear rate is reduced to above 50% as compared to dry-sliding wear. In ethanol as a lubricant, the wear rate is reduced by 92% and 35% as compared to dry-sliding and mustard oil lubricants respectively. Finally from the SEM images related to the wear mechanism, a combination of adhesive, abrasive, and fatigue wear is visible in both dry-sliding and lubricating conditions.
