Description

本考案は、チタン合金結合部品に関するものであり、特に、非腐食特性を有し表面に高硬度の窒化チタン層を具える結合部品技術領域に係る。   The present invention relates to a titanium alloy bonded part, and more particularly to a bonded part technical field having a non-corrosive property and a high-hardness titanium nitride layer on the surface.

図１に、通常見られる結合部品１０を示す。その結合部品１０はボルト１０１またはナット１０２とし、未図示であるリベットとすることも可能である。結合部品１０は通常、熱処理により硬度を強化している。   FIG. 1 illustrates a commonly found coupling component 10. The connecting part 10 may be a bolt 101 or a nut 102 and may be a rivet (not shown). The joint component 10 is usually hardened by heat treatment.

また、図２に示したのは、スクリューネジ１０４形状の結合部品１０である。その結合部品１０は主に、プレスクエンチ加工で成形する故、多くの場合軟質鉄系材料で製作しているが、鉄系材質には、酸化し易く、酸やアルカリの侵食に対する耐用性を持たない問題が残る為、結合部品１０を長期的に使用すると錆侵食による折れや崩れ等を引き起こす可能性がある。また、結合部品１０の強度を強化したい場合、高硬度材質を選択し加工する必要があるが、鉄系は炭素量の高低によりその強度をコントロールし、炭素量が高くなればなる程、硬度も高くなる。しかし同時に脆く折れ易い特性を伴うことになる故、結合部品１０を高硬度のスクリューネジ１０４とした場合、脆く折れ易く、金属板５０接合に使用できない欠点を持つ。   FIG. 2 shows a connecting part 10 having a screw screw 104 shape. Since the joint component 10 is mainly formed by press quench processing, it is often made of a soft iron-based material. However, the iron-based material is easily oxidized and has resistance to erosion of acids and alkalis. Since there is no problem, if the coupling part 10 is used for a long time, it may cause breakage or collapse due to rust erosion. In addition, when it is desired to strengthen the strength of the joint component 10, it is necessary to select and process a high-hardness material. However, the strength of iron-based steels is controlled by the amount of carbon, and the higher the carbon content, the higher the hardness. Get higher. However, at the same time, since the joint component 10 is made of a high-hardness screw screw 104 because it is brittle and easily broken, it has a drawback that it is easily broken and cannot be used for joining the metal plate 50.

前述した通り、鉄系材質の結合部品１０には錆侵食による折れ等の問題が残り、寿命が短い故、実施時には、何度も取り外して交換しなければならない。よって、高炭素量を含む鉄系材質の結合部品１０には脆く壊れ易い欠点がある為、現有する結合部品１０はまだ理想的なものとは言えない。   As described above, the connection part 10 made of an iron-based material still has problems such as breakage due to rust erosion, and has a short life, so it must be removed and replaced many times during implementation. Therefore, since the connecting part 10 made of an iron-based material containing a high carbon content has a drawback that it is brittle and easily broken, the existing connecting part 10 is not yet ideal.

前述の通り、現有する鉄系材質の結合部品には、錆侵食による折れ、脆く壊れ易い欠点がある故、本考案の考案者は思考を続けた結果、結合部品の材質自身に耐腐食性のあるチタン合金を選択し、且つ、チタン合金材質で製作した結合部品に窒化熱処理を施し、結合部品に突破性を与え効果を向上させた。   As described above, the existing iron-based joint parts have the disadvantages of being broken due to rust erosion, being brittle and fragile. A titanium alloy was selected and a nitriding heat treatment was applied to the bonded part made of a titanium alloy material to give the bonded part a breakthrough and improve the effect.

本考案の結合部品は、チタン合金材質により製作されたチタン合金結合部品であり、且つ、チタン合金結合部品には、窒化熱処理を施し、その表面に高硬度の窒化チタン層を形成する。即ち、本考案のチタン合金結合部品は、その表面に高硬度の窒化チタン層を具えるものである。   The bonded component of the present invention is a titanium alloy bonded component manufactured from a titanium alloy material, and the titanium alloy bonded component is subjected to nitriding heat treatment to form a high hardness titanium nitride layer on the surface thereof. That is, the titanium alloy bonded part of the present invention has a high hardness titanium nitride layer on its surface.

チタン合金結合部品は、熱処理を繰り返し行い改質硬化させる。また、チタン合金結合部品の表面に窒化チタン層を生成するが、その硬度は２０００ＨＶから３５００ＨＶ間とする。尚、該チタン合金結合部品はボルトまたはナットまたはリベットとして実施する。   Titanium alloy bonded parts are subjected to heat treatment repeatedly to be reformed and hardened. Further, a titanium nitride layer is formed on the surface of the titanium alloy bonded part, and its hardness is between 2000 HV and 3500 HV. The titanium alloy bonded part is implemented as a bolt, nut or rivet.

本考案は、チタン合金結合部品を提供することにあり、そのチタン合金結合部品は、材質自体に抗腐食金属性を有し、且つ、表面には窒化熱処理を施した高硬度の窒化チタン層を具えており、該チタン合金結合部品は、抗腐食及び高硬度の効果がある故、公知の結合部品の錆侵食による折れ、脆く壊れ易い問題を解決する。   The present invention is to provide a titanium alloy bonded part. The titanium alloy bonded part has an anti-corrosive metal property in the material itself, and a hard titanium nitride layer subjected to nitriding heat treatment on the surface. In addition, the titanium alloy bonded part has the effects of anti-corrosion and high hardness, so that it solves the problem of breakage, brittleness and breakage of the known bonded parts due to rust erosion.

まず図３に、本考案のチタン合金結合部品における実施例１を示す。該チタン合金結合部品１は、チタン合金材質によって製作され、その表面には窒化熱処理を施し、窒化熱処理によりその表面に高硬度の窒化チタン層１１を形成する。即ち、本考案のチタン合金結合部品１の表面には高硬度の窒化チタン層１１を具え、該窒化チタン層１１の硬度は２０００ＨＶから３５００ＨＶ間とする。
前記のチタン合金結合部品１はボルト（図３参照）、ナット（図４参照）、またはリベット（図５参照）とする。 First, FIG. 3 shows Example 1 of the titanium alloy bonded part of the present invention. The titanium alloy bonded component 1 is made of a titanium alloy material, and the surface thereof is subjected to nitriding heat treatment, and a high hardness titanium nitride layer 11 is formed on the surface by nitriding heat treatment. That is, the surface of the titanium alloy bonded part 1 of the present invention is provided with a high hardness titanium nitride layer 11, and the hardness of the titanium nitride layer 11 is between 2000 HV and 3500 HV.
The titanium alloy bonded part 1 is a bolt (see FIG. 3), a nut (see FIG. 4), or a rivet (see FIG. 5).

前述の通り、チタン合金結合部品１自体は、相当な硬度があり錆の出ないチタン合金金属製であり、チタン合金結合部品１の比重は極めて軽く、金属疲労現象が起き難く、加えてその表面の窒化チタン層１１の硬度は２０００ＨＶから３５００ＨＶ間である故、チタン合金結合部品１は、多くの優れた特異な特色を融合する。   As described above, the titanium alloy bonded part 1 itself is made of a titanium alloy metal which has a considerable hardness and does not rust, and the specific gravity of the titanium alloy bonded part 1 is extremely light and hardly causes a metal fatigue phenomenon. Since the hardness of the titanium nitride layer 11 is between 2000 HV and 3500 HV, the titanium alloy bonded part 1 fuses many excellent unique features.

次に図６及び図７を参照する。まず、チタン合金結合部品１はスクリューネジ形状に製作することも可能である（図６参照）。それは高硬度特性を持つスクリューネジ形状のチタン合金結合部品１の実施例であり、製作後の表面強度を利用して金属板Ｅに進入させることも可能である（図７参照）。   Reference is now made to FIGS. First, the titanium alloy bonded part 1 can be manufactured in a screw screw shape (see FIG. 6). This is an embodiment of the screw / screw-shaped titanium alloy bonded part 1 having high hardness characteristics, and it is possible to enter the metal plate E by using the surface strength after manufacture (see FIG. 7).

前述した通り、本考案のチタン合金結合部品１自身は相当な硬度があり錆の出ない金属製であり、且つ比重が極めて軽く、金属疲労が起き難く、抗腐食能力が良好で、且つ、チタン合金結合部品１表面には高硬度の窒化チタン層１１を形成し、窒化チタン層１１の硬度は２０００ＨＶから３５００ＨＶ間である。よって、チタン合金結合部品１は、硬化強度があり高硬度の窒化チタン層１１表面を具えており、公知の錆侵食による折れ、脆く壊れ易い欠点を効果的に解決し、且つ、チタン合金結合部品１自体は腐食し難い金属である故、錆侵食による心配がなく、環境汚染問題を解決し、無汚染の環境保護概念に基づくものである。   As described above, the titanium alloy bonded part 1 of the present invention is made of a metal that has a considerable hardness and does not generate rust, has a very low specific gravity, hardly causes metal fatigue, has a good anti-corrosion ability, and is made of titanium. A high hardness titanium nitride layer 11 is formed on the surface of the alloy-bonded component 1, and the hardness of the titanium nitride layer 11 is between 2000 HV and 3500 HV. Therefore, the titanium alloy bonded part 1 has a hardened and hardened titanium nitride layer 11 surface, effectively solves the known rust erosion, brittle and fragile defects, and the titanium alloy bonded part. Since 1 itself is a metal that does not corrode easily, there is no concern about rust erosion, it solves the environmental pollution problem, and is based on a pollution-free environmental protection concept.
