Plasma sprayed Multicomponent wear resistant coatings for Textile machinery with emphasis on self-lubrication

摘要

All textiles manufacturing machines encounter continuous friction between machine components and moving thread. It leads, among other things to wear of components, thus causing mis-alignment, vibration and damage to fibers and yarn. Although lubrication is universally used to avoid friction related wear, but in case of fiber processing lubrication can deteriorate fiber/fabric quality. The present work aims to develop multicomponent composite coatings by plasma spraying for textile machinery components with emphasis on self-lubricious coatings obtained through addition of solid inorganic lubricants. Tribological properties of plasma sprayed coalings of (Cr{sub}2O{sub}3.CaF{sub}2, Cr{sub}2O{sub}3.BaF{sub}2, Al{sub}2O{sub}3.TiO{sub}2.MoS{sub}2) has been analysed.
