An aqueous slurry containing Ni powder and optionally Cu and/or Sn is applied to a steel strip and sintered and then rolled to form a corrosion resistant coating. The steel strip may be vibrated during the application of the slurry may contain methyl cellulose and a surfactant as well as water. Particles of ThO2 and Al2O3 ranging from 0.01 - 50 microns may be included in the slurry or a second slurry containing these oxides may be applied to the first Ni slurry. The steel strip may first be coated with Cu or Sn or up to 90% Cu may be included in the Ni slurry with or without Sn. The sintered coating is cold rolled and optionally resintered, annealed at 500 - 800 DEG C. and may then be electroplated with Cr. The layer of slurry may be rolled after drying and prior to sintering. |
