計外装としての外観を満足させることが出来なかった。Conventionally, copper alloy materials, which are superior in stamping properties and machinability to stainless steel materials and are inexpensive, have been widely used for watch exterior parts whose surfaces are wet-plated. When a carbonitride film is directly formed on a copper alloy material using the ion plating method in vapor phase plating, dezincing occurs in a high vacuum atmosphere due to the temperature rise inside the Pelger, causing the surface of the copper alloy material to deteriorate. had a yuzu skin appearance, the corrosion resistance of the surface was reduced, and as a result, the appearance as a watch exterior could not be satisfied.

の使用に耐えなかった。Further, since the copper alloy itself has poor corrosion resistance, it has been difficult to satisfy the corrosion resistance as a watch exterior part due to the presence of pinholes in the ion plating film. Corrosion resistance can be improved by applying nickel, zinc, cadmium) to the base plating to improve corrosion resistance, but due to the difference in thermal expansion coefficient between these base plating layers and the surface chromium carbonitride layer, ion plating is As the substrate temperature decreased after the heating operation was completed, a peeling phenomenon occurred between the base plating layer and the chromium carbonitride compound layer, making it unusable as a watch exterior part.
