편마찰 실험을 이용한 합금화 온도별 GA 강판의 마찰특성에 관한 연구
A study on frictional characteristics in galvannealed sheet steel using one flat friction test
- Published : 2005.06.01
Abstract
As GA(Galvannealed sheet steel, GA) has good corrosion resistance, weldability and paintability as well as excellent stamping formability it's demand is rapidly increasing for automotive panel. But the layer of the Galvannealed sheet steel is easy to have a coating layer such as powdering and flaking in the press process because it is composed of Fe-Zn alloy. Therefore, the process condition is properly required to form the surface treated sheet steel. The frictional characteristics with dies are changed according to the annealing temperature,
