no. 1 approach

[0046] figure 1 It is a sectional view schematically showing the first embodiment of the timepiece component of the present invention. Below, for figure 1 The upper side in , which is the viewpoint side of the observer, will be described as a center (for the Figure 2 to Figure 5 also the same).

[0047] The watch part 10 includes: a base material 1; a base material 1 containing Co as a main component, a content rate of 26% by mass to 30% by mass, Cr, and a content of 5% by mass to 7% by mass. The first film 2 is made of a material containing Mo.

[0048] With the above configuration, it is possible to provide a timepiece component 10 that is excellent in aesthetics (especially high gloss and luxurious appearance), excellent in corrosion resistance, and also excellent in scratch resistance and abrasion resistance. In particular, even without using precious metals as the main material, it is possible to obtain a highly glossy and luxurious appearance. In addition, even whe...

no. 2 approach

[0096] Next, a timepiece component according to a second embodiment will be described.

[0097] figure 2 It is a cross-sectional view schematically showing a second embodiment of the timepiece component of the present invention. In the following description, differences from the above-described embodiment will be mainly described, and descriptions of the same matters will be omitted.

[0098] In the timepiece component 10 of the present embodiment, on the surface of the substrate 1, an underlayer (first underlayer) 3 composed of a material containing Ti is sequentially laminated; % to 30% by mass, and the first coating 2 is made of a material containing Cr at a content of 5% to 7% by mass and Mo at a content of 5% to 7% by mass. In other words, in the timepiece component 10 of the present embodiment, the base layer 3 made of a material containing Ti is provided between the base material 1 and the first coating 2 .

[0099] Thereby, the adhesiveness between the base materia...

no. 3 approach

[0109] Next, a timepiece component according to a third embodiment will be described.

[0110] image 3 It is a cross-sectional view schematically showing a third embodiment of the timepiece component of the present invention. In the following description, differences from the above-mentioned embodiment will be mainly described, and the description of the same matters will be omitted.

[0111] In the timepiece component 10 of the present embodiment, on the surface of the base material 1, an underlayer (first underlayer) 3 made of a material containing Ti, an underlayer made of at least one selected from TiC and TiCN are sequentially laminated. The second coating film 4 is made of a material of Co, and contains Co as a main component at a content rate of 26% by mass to 30% by mass, and contains Cr at a rate of 5% by mass to 7% by mass. The first coating 2 is made of a material containing Mo. In other words, it is the same as the second embodiment described above except that ...

Abstract

Provided are a timepiece part having an outstanding appearance, outstanding corrosion resistance, and outstanding scuff resistance and wear resistance; and a timepiece having the timepiece part. The timepiece part has a substrate; and a first coating made from a material containing Co and including greater than or equal to 26 wt% and less than or equal to 30 wt% Cr, and greater than or equal to 5wt% and less than or equal to 7 wt% Mo. The substrate is preferably made from a material including at least one of stainless steel and Ti. A second coating made of a material including at least one ofTiC and TiCN is preferably disposed between the substrate and first coating.

Description

technical field [0001] The present invention relates to a watch component and a watch. Background technique [0002] Clocks are required to function as utility items, and to have excellent aesthetics (beautiful appearance) as decorations. [0003] Therefore, precious metal materials having excellent texture are used for watch parts such as watch cases and bands (for example, refer to Patent Document 1). [0004] However, precious metal materials are generally expensive, and have problems such as low hardness and easy damage (poor abrasion resistance). [0005] Patent Document 1: Japanese Patent No. 2990917 Contents of the invention [0006] An object of the present invention is to provide a timepiece component having excellent aesthetics, corrosion resistance, scratch resistance, and abrasion resistance, and a timepiece including the timepiece component. [0007] Such objects are achieved by the present invention described below. [0008] The watch component of the pre...
