本考案は刃物に係り、特に特定のアモルフアス
合金の被覆層を形成することにより、従来の刃物
の耐食性等を改善した刃物に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to cutlery, and particularly to a cutter in which the corrosion resistance of conventional cutlery is improved by forming a coating layer of a specific amorphous alloy.
現在、包丁、鋏やカミソリ、ひげそり具等の替
刃、その他カツターナイフ等の刃物は、炭素鋼等
の金属製のものが主流である。
Currently, replacement blades for kitchen knives, scissors, razors, shaving tools, and other blades such as cutter knives are mainly made of metal such as carbon steel.

る。 However, although carbon steel blades have excellent sharpness, they have the problem of rust and cannot be used when the object to be ground has a high moisture content or when used in a humid atmosphere. However, there is a drawback that rust occurs significantly. especially,
Rust occurs on the cutting edge and body of knife 1 (Fig. 2a)
This is noticeable at the M part of the blade) and the base of the cutlery.
このような問題を解決するものとして、ステン

ユポン社製）も提案されている。 To solve these problems, stainless steel (for example, 13Cr martensitic) blades have been provided. In addition, to further increase the added value, as shown in Figure 2b, a TiN coating layer (layer thickness is about 5 μm) 2 is applied to the surface of the stainless steel knife by IP (ion plating). There is also one that is provided on the main body 3 to increase the hardness and is colored gold. Others, 2nd
As shown in FIG. c, there has also been proposed a cutter body 3 which is silver-stoned and Teflon 4 is baked on (manufactured by Dupont).

た。
However, among these conventional cutlery, although the stainless steel cutter 1 has improved its corrosion resistance to some extent, it cannot reliably prevent the occurrence of rust, and there is a limit to how hard it can be increased.
また、TiNの被覆層２を設けたものでは、刃
先部分３の硬度がステンレス鋼の場合通常Hv600

ある。しかも、I.P法で形成した被覆層は色ムラ
を生じ易く、その商品価値を損なう場合もある。 In addition, with the TiN coating layer 2, the hardness of the cutting edge portion 3 is usually Hv600 when made of stainless steel.
~650, whereas the hardness of TiN layer 2 is
Since the hardness is about 2000 Hv, the difference in hardness is too large, causing the problem of peeling of the coating layer at the cutting edge of the knife, and in severe cases, the blade may chip. Moreover, the coating layer formed by the IP method tends to cause color unevenness, which may impair its commercial value.
更に、シルバーストーン加工を施したものは、

Although it is effective in preventing rust, once a scratch occurs, rust will begin to form in that area, and Teflon 4
There is also the problem that it is easy to peel off. Moreover, since the color of silverstone-finished products is limited to blackish brown, it is not very aesthetically pleasing.
本考案は、上記従来の刃物の問題点を解消する

As is well known, amorphous metals are metals that are not crystallized and have a glass-like structure with no regularity in their atomic arrangement, and have physical and chemical properties not found in general crystalline metals. are doing.
Therefore, the amorphous amorphous alloy with a specific composition according to the present invention has particularly high hardness, high toughness, and excellent corrosion resistance, and has excellent corrosion resistance against acids such as hydrochloric acid, nitric acid, sulfuric acid, acetic acid, and formic acid. have
このため、本考案により刃物の本体をこの特定
組成のアモルフアス合金で被覆することにより、
極めて優れた耐食性を有する刃物を得ることがで
きる。 Therefore, by coating the main body of the cutlery with an amorphous alloy of this specific composition according to the present invention,
A cutlery having extremely excellent corrosion resistance can be obtained.

Therefore, when an amorphous alloy having this composition is placed in an oxidizing environment, an extremely uniform protective film (passive film) having high corrosion resistance is formed on its surface. Therefore, this passive film exhibits sufficiently high corrosion resistance.
本考案において、アモルフアス合金の被覆層１１

ことが可能である。In the present invention, the amorphous alloy coating layer 11
may be provided so as to cover the entire knife body 10 as shown in FIG. It may be provided to cover. In addition,
Even when the entire blade body 10 is coated as shown in FIG. 1a, the cutting edge can be polished in the same way as a normal blade.
被覆層１１の厚さは、刃物の用途等に応じて決

程度、例えば約10μｍ程度とする。又、刃先部分
を被覆する場合は切れ味を損なわないために5μ
ｍ以下が好ましい。 The thickness of the coating layer 11 is determined depending on the purpose of the knife, etc., but the thickness of the knife body is usually 5 to 20 μm.
For example, about 10 μm. Also, when coating the cutting edge, 5 μ
m or less is preferable.
このようなアモルフアス合金の被覆層は、常

タリング法による場合には、緻密な被覆層がムラ
無く均一に得られることから極めて有利である。 Such an amorphous alloy coating layer can be formed by a conventional method, for example, a sputtering method, a vapor phase deposition method such as a vacuum deposition method. In particular, the sputtering method is extremely advantageous because a dense coating layer can be obtained evenly and uniformly.

Hv900〜1100程度であるため、硬度差による剥離
は殆ど起こらない。 The resulting amorphous alloy coating layer has an adhesion force comparable to that of the NiT layer obtained by the conventional IP method, but its hardness is comparable to that of the blade body.
Since the Hv is about 900 to 1100, peeling due to hardness differences hardly occurs.
また、アモルフアス合金は通常は銀色を呈して
