Title: Low friction coatings for lubricant free use in rail points
Abstract: The development of different concepts for low friction coatings e.g. self lubricating coatings, lubricants sealed coatings or materials consisting of low friction matrices reinforced with wear resistance particles, has increased. Various experimental investigations concerning the wear and corrosion resistance of different coatings give a good insight into the different concepts. 22 coatings materials sprayed by using atmospheric plasma (APS) or high velocity oxy-fuel (HVOF) techniques were compared. A special testing facility was designed to investigate the wear resistance of the coatings to dry friction as well as to water lubrication and sand on the treated surface. The properties of the best coatings can be transferred into practice.
