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。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,以及在此领域内的研发进展,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。新型表面技术及个性化表面产品将成为未来开发钢铁新产品的基础和高端钢铁产品的核心。
Automotive pre-coated steel with the realization of modular car design get more and more attention. This paper introduces the structure, technical characteristics and development goals of future automotive surface products of steel enterprises and their research and development progress in this field. The structure, properties and future application goals of zinc-magnesium alloy coatings are discussed. The different strip steel The application of vacuum coating system and the difference of different coating processes, zinc-magnesium alloy coating can be used as a new generation of metal coating substrate with good comprehensive performance. Based on this, the SiOC series coating can be used as a subsequent coating to complete the pre-coating Finish the plate. The process will likely lead the industrialization of modular automotive parts and personalization and high-end products. New surface technology and personalized surface products will become the core of the future development of new steel products and high-end steel products.
