Abstract: The objective of this project is to study the corrosion that occurs in Railway coach’s bogie components, causes of corrosion, steps taken to prevent corrosion, suggestions to minimize this problem. This paper contains new suggestions to minimize the problems: more emphasis has been laid on Polytetrafluoroethylene (Teflon) coating to be suggested instead of black enamel or epoxy coating for bogie frame and bogie components of equalising rod and brake beam. The under mentioned components are the most affected parts due to corrosion near the bottom of lavatory. Another reason for bogie frame corrosion is easy peeling off coating surfaces due to scratch or dent marks produced by striking of ballast when trains are running. The corrosion prevention behavior of commercially available epoxy coated surfaces and Teflon coated surfaces on structural steel were evaluated using various methods such as 3.5 wt. % Na Cl solution salt spray test, 25% (v/v) sulphuric acid immersion test and loss of weight. Two different systems of coatings were selected for evaluation. The test panels same as of bogie component material composition were prepared and subjected to specific test as per experimental procedure. Optical microscope image were recorded on completion of corrosion test. We observed that after 504 hrs. exposure in atmospheric, Teflon coatings are still good in resisting abrasion and can withstand against corrosion more effective than other coatings.
