Abstract (en)
[origin: WO9632522A1] The novel process serves simultaneously to inhibit corrosion and to improve adhesion characteristics of reinforcing metals for and in cement systems. It involves surface treatment of the metal parts by Fe-, Ca/Zn, Zn or Mn-phosphatisation and subsequent surface treatment using an aqueous solution or slurry of reducing and/or passivating compounds (such as nitrites, chromates, hydrazine or hydrazine derivatives, hydroxylamine or hydroxylamine derivatives), and/or organic corrosion inhibitors. If necessary, the phosphate layers can undergo subsequent impregnation with non-aqueous or aqueous solutions of other corrosion inhibitors, e.g. vapour phase inhibitor, adhesive promotors, metal-non-metal sols and/or concrete/cement additives.
