摘要
Aluminum films coated on DI steel sheets were prepared by direct current （DC） magnetron sputtering.The influence of the deposition conditions and film thickness on the formability of coated steel sheets was studied.The results of the cupping test and drawing test show that the substrate temperature and thickness of Al films are the key factors that affect Al adhesion and formability of coated steel sheets.Adhesion became worse when the thickness of Al sheets was more than 2 μm.And formability was improved remarkably when the substrate temperature was increased to 200℃.
