Stress Assisted Tribofilm Growth: A New Model

18.04.2017 tribonet 324 Views
Under extreme conditions the lubricant film fails to separate the rubbing surfaces and solid-to-solid contact occurs. To prevent excessive wear of the base materials anti-wear additives are used in these cases. The additives create a […]
