摘要

ABSTRACT The process of Quick Plastic Forming (QPF) developed by General Motors involves hot aluminum forming at ～450℃, and has formability advantages over conventional stamping of aluminum or steel. However, there are still no fully satisfactory solutions for the problem of local interaction/sticking between the aluminum blank and the tool, and the eventual transfer of some aluminum to the steel tool after repeated forming cycles. In this paper we show that the process of anodizing aluminum prior to forming greatly diminishes the interaction of aluminum with steel at QPF forming temperatures. Significantly improved tribological behavior of the aluminum surface after anodization as compared to lubricated aluminum was shown on a laboratory scale with flat-on-flat reciprocating experiments.
