摘要： A method for producing a composite steel strip having a high corrosion resistance comprises electroplating a steel strip substrate in an electroplating bath to codeposit a zinc-based metal matrix and corrosion-preventing fine solid particles. The particles comprise a core which may be, for example, chromate, phosphate, aluminum, molybdenum or titanium compounds and a thin coating membrane which may be, for example, SiO.sub.2, Al.sub.2 O.sub.3, ZrO.sub.2, TiO.sub.2 or a resin encapsulating the core. The core material is soluble in the electroplating bath while the coating membrane is substantially insoluble in the electroplating bath. The electroplating bath also contains an agent for promoting the codeposition of the zinc-based metal matrix and the particles, and may optionally include a number of additional fine particles which may be, for example, SiO.sub.2, TiO.sub.2, Cr.sub.2 O.sub.3, Al.sub.2 O.sub.3, ZrO.sub.2, SnO.sub.2, or Sb.sub.2 O.sub.5.
