Continuous Physical Vapor Deposition of Steel Strip Coating:Research Progress and Current Applications
The global consensus on"carbon peak and carbon neutrality"has intensified focus on the new generation of high-strength steel,pivotal in advancing energy conservation and emission reduction in the steel industry and automotive lightweight strategies.Traditional coating methods like electro-galvanized zinc are struggling to meet surface protection demands due to hydrogen embrittlement risks,stringent environmental regulations,and the poor platability of hot-dip galvanizing.Physical Vapor Deposition technology,leveraging vacuum coating,has adeptly resolved these issues in electroplating and hot-dip galvanizing for new generation high-strength steel.PVD's exceptional surface quality,robust adhesion,diverse coating material options,and environmental advantages mark it as a crucial advancement in next-generation surface engineering technologies.This paper reviews the application and development prospects of PVD in replacing traditional corrosion-resistant coating technologies for strip steel(such as electroplating and hot-dip galvanizing),with a particular focus on the thermal evaporation method of PVD,the development history of continuous PVD coating for strip steel,research progress,and its current status in industrial applications.Finally,the review underscores the agenda for future research directions.
