Effects of Fe powder on sliding wear processes under lubricants with different viscosities

Four sliding wear tests were conducted using a ball-on-disc tester at room temperature to investigate sliding wear processes in which Fe powders were added to the lubricant. The ball sample was a standard E52100 ball of 8 mm in diameter. The disc samples were made of 5140 steel and heat-treated to a...

Description
Summary:Four sliding wear tests were conducted using a ball-on-disc tester at room temperature to investigate sliding wear processes in which Fe powders were added to the lubricant. The ball sample was a standard E52100 ball of 8 mm in diameter. The disc samples were made of 5140 steel and heat-treated to a hardness of 52 HRC. Wear debris analysis and surface analysis of the tested samples were carried out to investigate the wear particles generated from the wear process and to study the effects of the soft Fe powder. It was proved that Fe powders in the lubricant played an important role in the wear process and had a significant effect on the main wear mechanisms, resulting in wear-out failure.
