Abstract
A surface reforming method of a metal product, wherein a platinum film is formed on the surface of a metal product by injecting onto that surface a nitrogen ion, a carbon ion and a platinum ion in that order, and then injected onto said platinum film a second platinum ion with the aim of improving the exfoliation resistance of the platinum film being formed on the metal surface, and the abrasion resistance of the surface.
