An adhesion amount of Sn per surface of the Sn-plated steel sheet is 0.1 g/m.sup.2 or more and 15 g/m.sup.2 or less, an amount of the zirconium oxide in the film layer is in a range of 1 mg/m.sup.2 or more and 30 mg/m.sup.2 or less in terms of an amount of metal Zr, a peak position of a binding energy of Sn3d.sub.5/2 of the tin oxide is 1.4 eV or more and less than 1.6 eV from a peak position of a binding energy of metal Sn, and a quantity of electricity required for reduction of the tin oxide is more than 5.0 mC/cm.sup.2 and 20 mC/cm.sup.2 or less.

The present invention relates to a method of inhibiting corrosion of steel in contact with a corrosive solution. The method involves mixing an olive leaf extract titanium nanocomposite with the corrosive solution. The olive leaf extract titanium nanocomposite may be made by reducing TiCl.sub.4 with an olive leaf extract, which forms nanoparticles with an average size of 50-100 nm.

An aqueous solution (20) is an aqueous solution used for repairing an aluminum-coated steel wire (10) with defects leading to there being iron, which contains magnesium chloride having a concentration of 10% or more, and magnesium sulfate having a concentration of 6% or more, and which allows an anticorrosion layer made of an alloy component of magnesium and aluminum to be formed.

The purpose of the present invention is to provide: a functional material which is prepared by using aluminum as a base material and has a bactericidal effect; and a method for producing the functional material. The functional material comprises an aluminum base material and a functional film which is a hydrated aluminum oxide film formed on the surface of the aluminum base material. The functional film has nano-order depressions and protrusions formed on the surface thereof and, as a result, the functional film can have a bactericidal effect to kill bacteria. The functional material is produced by subjecting an aluminum base material to a boiling treatment in boiled water for a predetermined treatment time to form, on the surface of the aluminum base material, a hydrated aluminum oxide film having nano-order depressions and protrusions formed on the surface thereof.

Disclosed herein is a method for applying metals to clay. More particularly, the present invention relates to applying malleable metals, such as silver, to clay, such that the metal attaches to the clay and as an added feature forms beads on the surface of the clay.

The invention relates to an aqueous stripping composition for the removal of polymeric surface sealants on metal surfaces, said stripping composition comprising an alkalizing agent, a polymer splitting agent, a swelling agent, and a cloud point booster, wherein said polymer splitting agent is at least one gluconate wherein said swelling agent is at least one compound selected from the group consisting of glycol ethers and aliphatic alcohols having 3 to 9 carbon atoms. The inventive aqueous stripping composition is capable to remove polymeric sealants like e.g. polyurethane sealants, polyethylene sealants, polyethylene waxes, polyacrylic sealants, polysilicate sealants, and the like.
