Description
本発明の製造方法において、第１の硬質皮膜上を研磨するのは、ドロップレットやパーティクル等を除去して、平滑な表面状態にするためである。これによって、第２の硬質皮膜の被覆時には、第１の硬質皮膜表面の微細な凹凸を埋めるように被覆され、皮膜全体の耐食性を大幅に改善できる。
本発明の製造方法で被覆される第１の硬質皮膜の表面は、具体的にはＪＩＳ−Ｂ−０６０１−２００１に定められる表面粗さにおける算術平均粗さＲａは０．０５μｍ以下とし、かつ最大高さＲｚは１．００μｍ以下に研磨することで耐食性を向上させる。より好ましくは、Ｒｚは０．５μｍ以下に研磨する。
In the production method of the present invention, the reason why the first hard film is polished is to remove droplets, particles, and the like to obtain a smooth surface state. Thus, when the second hard film is coated, the first hard film surface is coated so as to fill fine irregularities, and the corrosion resistance of the entire film can be greatly improved.
Surface of the first hard coating film to be coated by the process of the present invention has an arithmetic mean roughness Ra of the surface roughness in particular defined in JIS-B-060 1 -2001 is set to 0.05μm or less, and Corrosion resistance is improved by polishing the maximum height Rz to 1.00 μm or less. More preferably, Rz is polished to 0.5 μm or less.
（表面粗さ測定）
ＪＩＳ−Ｂ−０６０１−２００１に従って、粗さ曲線より算術平均粗さＲａと最大高さＲｚを測定した。測定条件は、評価長さ：４．０ｍｍ、測定速度：０．３ｍｍ／ｓ、カットオフ値：０．８ｍｍとした。
(Surface roughness measurement)
According JIS-B-060 1 -2001, it was measured arithmetic mean roughness Ra and maximum height Rz than the roughness curve. The measurement conditions were as follows: evaluation length: 4.0 mm, measurement speed: 0.3 mm / s, cut-off value: 0.8 mm.
