産業上の利用分野
本発明は金属製腕時計用ケースの硬化処理法に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for hardening metal watch cases.
従来技術 従来時計用ケースの硬質化は、超硬合金やｃ。Conventional technology Conventional hardened watch cases are made of cemented carbide or c.
合金などを用いるか、ステンレス鋼に１’ＶＤ処理によ

ズが付きやすいなどの欠点がある。However, cemented carbide and CO alloy have poor workability and are very expensive. Furthermore, although coating stainless steel by PVD treatment is inexpensive, it has drawbacks such as being prone to scratches because the coating layer is thin.

ことを目的とするものである。Purpose of the Invention The present invention solves these drawbacks by applying nickel-tungsten alloy plating or baradium plating to a metal wristwatch case, and then subjecting it to a further KPVD treatment.
4N11-coating and age-hardening the nickel-tungsten alloy plating layer,
The purpose is to manufacture a watch case that is extremely scratch resistant at a low price.
発明の構成 以下本発明の製造方法を詳細に説明する。Composition of the invention The manufacturing method of the present invention will be explained in detail below.

いなければならない。First, watch cases are made of stainless steel, brass,
The reason why we limited it to metals such as nickel silver is because high heat of 400 to 600 degrees Celsius is required to apply nickel-tungsten alloy plating and to age-harden the nickel-tungsten alloy plating layer, so the materials that can be plated are heat-resistant. must have.

い。The first step is to apply nickel/tungsten alloy plating. At this time, the appropriate tungsten content is 10 to 45 wt, since cracks may persist during the plating process and age hardening process, and plating adhesion failure may occur. Also, if the thickness of the plating is less than 1°pm, it will not be effective against scratches caused by bumping (but if it is more than 60pm, the cost of plating will increase unnecessarily, so a bait of 10μ to 60μ is better.
第２の工程では、パラジウムメッキを１μ常程度施す。In the second step, palladium plating is applied to approximately 1 μm.
これは耐食性向上の目的であり他の貴金属メッキでも良
