る。[Prior Art] As a method for bonding ceramics such as sapphire and metal, it is common to use an active metal method or bonding via a metallized intermediate layer. In the active metal method, a brazing material containing active metals such as Ti and Zr improves wettability with ceramics such as alumina, sapphire, WC, TiC, and TiN, achieving good bonding. A typical metallization method is the Mo-Mn method, in which a Mo and Mn mixed paste is applied, heated in a hydrogen atmosphere, and then Ni-plated. In addition, a metal multilayer film is applied on the ceramic surface by vapor deposition, sputtering, etc.
Some form a metallized layer with decorative properties.

くなる問題があつた。[Problems to be solved by the invention] However, although the active metal method enables direct brazing with metal, it has the drawback of significantly deteriorating decorative properties, and the Mo-Mn method only has a metallizing function, so it cannot be used for decoration. In order to form a metallized layer with decorative properties, it is necessary to have at least a three-layer structure: a decorative layer, a diffusion prevention layer, and a metallized layer.
Since a multilayer film formation structure is required, there is a problem in that the manufacturing cost increases.

It is bonded to a metal member using a Zr-containing brazing material, and a film made of one selected from metal nitride, metal carbide, and metal carbonitride is formed on the top surface of the brazed part of the sapphire glass to improve decorativeness. This is the structure of the sapphire cover glass for watches. Metal nitrides, metal carbides, and metal carbonitrides include TiN, TiC, and TiCN depending on the color tone.

Using reactive ion plating method at N2 gas flow rate of 400ml/min and pressure of 8×10 -4 Torr.
TiN2 was formed on the surface of 2 μm sapphire 1. this
Resist ink was applied so as to leave the upper and lower peripheral parts of the TiN layer, and etching was removed using a HF-HNO 3 mixture. Ni-plated Kovar 3 and Saphire 1 were then coated with Ti-containing Ag-Cu brazing material. Brazing was carried out by heat treatment at 900°C for 10 minutes using No. 4. If the brazing temperature is less than 850°C, Ti in the brazing material will not be sufficiently dissolved and will remain after brazing, and the wettability to TiN will not be sufficient. As a result, decorative sapphire glass was formed in which the soldered surface of the sapphire had a golden color. The watch case is integrated with the Kovar 3 part through the packing. The bonding strengths of this example and the conventional active metal method are: 160 kg for the inventive product and 20 to 30 kg for the conventional product. was found to decrease.
