Effect of ductility on dry sliding wear of medium carbon steel under low load conditions

摘要: The room-temperature dry sliding wear behavior of AI SI 1045 steel has been investigated with the aim clarifying effect ductility on Sliding tests were carried out in air using a pin-on-disk tester loads ranging from 4 to 12 N specimen higher showed lower rate than though their hardness values are similar SEM observations worn surfaces revealed that begins microploughmg process, which was followed by steady surface-platelet formation and its detachment Microscopic wearing as function distance clearly proved leads delayed sheets together detachment, resulted rates. It found microscopically ductility, rather hardness, is major controlling factor determining when proceeds through detachment.
