Tribological Behavior of AZ31B Magnesium Alloy Sheet during Sliding at High Temperatures

摘要

This investigation was undertaken to understand the interaction between steel tools and AZ31B magnesium alloy sheet during high-temperature forming. A new method of tribo-testing at high temperature, which involves reciprocating sliding of steel specimens against magnesium alloy sheet, was used to determine the effects of temperature and load. On the steel tool/magnesium sheet interaction. The coefficient of friction increased with increasing test temperature but decreased with increasing load.
