Abstract

PURPOSE:To obtain hard and lightweight outer ornament parts for watches having high corrosion resistance and excellent in color tone by laminating an undercoat Cr layer and a Ti-type hard finish layer on the surface of Ti by an ion plating method, further masking the above and then applying etching to the above. CONSTITUTION:An undercoat layer of Cr film and a finish layer of Ti-type hard film are laminated on the surface of outer ornament parts for watches composed of Ti or Ti alloy by means of coating by using an ion plating method. Proper thickness of the above Cr film is 0.2-5.0mum. Moreover, the above Ti-type hard film consists of one kind among gold color or dark gray series composed principally of the compounds of Ti, C, and N, dark brown series composed principally of the compounds of Ti, C, and O, and blue color series composed principally of the compounds of Ti and O, and proper thickness of this film is 0.2-2.0#Xm. Further, this film is partially masked, and then, the above Ti-type hard film is removed by means of etching using a mixed liquor of hydrofluoric acid and nitric acid and the above Cr film is also removed by means of anodic electrolysis using phosphoric acid bath, Subsequently, the masking film is removed, and the above parts are formed into two colors consisting of the color of the material and the color of the Ti-type hard film. By this method, the outer ornament parts for watches excellent in ornamental property can be obtained stably and inexpensively.

Alternatively, a Ti-based hard coating, which is a type of blue-based Ti-based hard coating mainly containing Ti and O compounds, is coated and laminated, and the coating is partially masked, and a Ti-based hard coating and a Ti-based hard coating are applied. By chemically etching the Cr film and then removing the masking film to finish in two colors: the material color and the Ti-based hard film color, we can take advantage of the light weight and high corrosion resistance of Ti or Ti alloys, and also create a hard coating. The present invention provides an exterior part for a watch that has excellent scratch resistance and abrasion resistance, and is finished in a Ti-based color coating with a rich variety of colors or in two colors: the material color and the Ti-based hard coating color.

[Prior Art] The conventional method for forming a Ti-based color film on the surface of a Ti or Ti alloy substrate by ion plating is to directly coat the surface of the substrate. In addition, two-color finishing using Ti or Ti alloy material and Ti-based color coating is possible after partially masking the surface of the material with a heat-resistant masking agent.
A common method is to apply a color film and dissolve and remove the masking film.

[Problem to be solved by the invention] However, the appearance and color quality of exterior parts for watches are particularly strictly controlled, and in ion plating processing, the defect rate due to defects outside the color tone limit, color unevenness, etc. is 3 to 5%. The conventional method for repairing these defective substrates is to peel off and remove the Ti-based color film using a mixture of hydrofluoric acid and nitric acid.
Since the Ti-based color film is directly coated on the i-alloy substrate surface, the substrate surface is also etched at the same time, and the high value-added substrate must be discarded or re-polished over a long period of time. Remedies were not possible, and problems had arisen in terms of delivery time and costs. In addition, in two-color finishing, when a Ti-based color film is applied after partially masking the surface of the material with a heat-resistant masking agent, gas is generated from the masking film, resulting in frequent defects such as color unevenness. In addition, in the case of a design with a large area of material color in terms of finished appearance, it takes a long time to apply masking, which causes problems in terms of delivery time, cost, and cost. The present invention is intended to solve these problems, and its purpose is to prevent defective products from being etched on the substrate surface during ion plating processing. It is possible to peel off and remove with a mixed solution and immediately perform re-ion plating processing.Furthermore, as a two-color finishing method, Ti
Color coating with hydrofluoric acid! By stripping and removing the Cr coating with a mixed solution of 1 acid, and then stripping and removing the Cr coating, we are able to rescue defective products and significantly reduce the defective rate.This results in shorter delivery times and lower costs, resulting in lightweight, high corrosion resistance, hardness, and scratch resistance.
It is an object of the present invention to stably provide at low cost an exterior part for a watch which has excellent abrasion resistance and is finished in a Ti-based color coating with a rich variety of colors or in two colors: the material color and the Ti-based hard coating color.
