汽车用预涂镀钢板随着模块化汽车设计的实现得到越来越多的关注，本文介绍了钢铁企业未来汽车用表面产品的结构、技术特征和发展目标，介绍了作者在此真空预镀钢板方向的研发进展，对锌镁合金镀层的结构、性能及未来应用目标进行了讨论，分析总结了不同带钢真空镀膜体系的应用方式及不同工艺镀层的差异，锌镁合金镀层可以作为新一代的具有良好综合性能的金属镀层基板，以此为基础，可以采用SiOC系列镀层作为后续镀层，进而完成汽车用预完成钢板。该工艺将有可能在模块化汽车零部件和个性化和高端产品领域率先实现工业化。

The pre-finished coated steel for automotive industry has gained more and more attention with the rapid progress of module design concept realiazation in automotive industry. The structure, technical characteristic and future target of future coated steel product for automotive industry has been discussed in this paper. The currently status of pre-paindted steel has been discussed. The application of vacuum strip coating process and products has been analyzed. The research progress by our group has been reported. It is shown that ZnMg alloy coated steel can be utilized as an innovative coated steel as substrate for pre-finished coated steel for automotive industry with comprehensive excellent properties. SiOC series coatings can be used further to fnish the pre-coated steel. Vacuum strip coating process and related products can be realized first in the automotive part production, module design process and niche product fileds.
