Abstract
Abstract A steel sheet is cleaned and coated with a particular treating solution. This solution is obtained by adding Mo, W, Cu or K ion to Ni ion as the respective aqueous solutions. The film formed thereon is excellent in anti-corrosion property and paintadherence property and the product steel sheet is suitable for use as a can or container for drinks, etc.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
133 words
A METHOD FOR THE MANUFACTURE OF A STEEL SHEET HAVING A NICKEL COMPOSITE FILM WHICH COMPRISES SUBJECTING A SURFACE OF A STEEL SHEET TO A CLEANING TREATMENT, COATING AN AQUEOUS SOLUTION ON SAID CLEANED SURFACE, SAID AQUEOUS SOLUTION BEING OBTAINED BY ADDING TO AN AQUEOUS SOLUTION CONTAINING A METALLIC ION OF NICKEL AT LEAST ONE MEMBER SELECTED FROM THE GROUP CONSISTING OF AN AQUEOUS SOLUTION CONTAINING A METALLIC ION OF MOLYBDENUM, AN AQUEOUS SOLUTION CONTAINING A METALLIC ION OF TUNGSTEN, AN AQUEOUS SOLUTION CONTAINING A METALLIC ION OF COPPER AND AN AQUEOUS SOLUTION CONTAINING A METALLIC ION OF POTASSIUM, HEATING THE SAME IN THE ATMOSPHERE OF A NON-OXIDIZING GAS, AND THEREBY FORMING ON SAID STEEL SHEET A FILM CONSISTING OF NICKEL AND AT LEAST ONE MEMBER SELECTED FROM MOLYBDENUM, TUNGSTEN, COPPER AND POTASSIUM.
