た。In general, surface treatments for exterior parts for mobile watches can be roughly divided into plating, painting, etching, etc. However, when stainless steel or copper alloys such as brass are used as the fabric material, there are problems in terms of wear resistance. In addition, the expression of color tone was also limited. In other words, in terms of abrasion resistance, the fabric is easily exposed due to scratches and abrasion during normal carrying. Regarding color tone, plating can only express gold or silver colors, and painting can express various colors, but it is significantly inferior in terms of abrasion resistance. Plasma spraying is widely known as a method for coating metals, alloys, or ceramics to impart wear resistance and heat resistance to the surface of metal materials.
Since there are many holes, many of which penetrate from the surface to the base material, their use as exterior parts for watches is extremely poor in corrosion resistance, so their use has been restricted.

,. By plasma spraying powder mainly composed of ceramic powder such as 2τ03, it is possible to produce colors such as black, white, green, blue, brown, etc., and by mixing pigments of the same color tone on top of it, tare 0 / series By applying a coating film of this paint to the bottom of the tank, we were able to create a color film that has high corrosion resistance and does not damage the hardness of the base, that is, the sprayed film. In our experiments, the roughness of the sprayed surface was 2 in terms of centerline surface roughness [RG].
When the thickness was between μ and 5μ, the adhesion with the Teflon paint was optimal and the appearance of the coating film was also optimal. Furthermore, coating thickness of Teflon paint material of about 5 μm to 15 μm was excellent in terms of wear resistance and corrosion resistance. It has been found that if the thickness of this coating is made thin, the corrosion resistance will be poor, and if it is made thick, the Teflon paint itself will be easily scratched because it is soft, although it has a low coefficient of friction of about 0.02. If the Teflon coating thickness is within the above range of 5μ to 15μ,
It was also found that the Teflon coach-in film itself was less likely to be scratched, without compromising the hardness of the sprayed film, and because it serves as a backup for the sprayed film.
以下に本発明の実施例を紹介する。Examples of the present invention will be introduced below.

I'm there to do it.

庭用の中性洗剤で容易に落すことが出来ることである。The reason why the ceramic powder was sieved through a 15μ sieve was to aim for a surface roughness i RCL = around 3μ after thermal spraying. Then, by applying Teflon paint mixed with rutile-based titanium to a thickness of 10 μm on the sprayed coating, a watch body and band with excellent abrasion resistance and high corrosion resistance can be obtained. Another advantage of the coating film is that with thermal sprayed coatings, the surface is rough and active, so it is difficult to remove dirt if a dirt spoon gets stuck to it, but with Teflon coating, even if dirt gets stuck, it is difficult to remove. It can be easily removed with poppy rubber or household neutral detergent.

In this case, even if the surface is scratched by something, the paint in the valleys of the sprayed film will never be completely fooled, and if only the peaks are exposed, it will not be white. No thermal spray film was visible.
