2. Description of the Related Art An outdoor component used for fishing equipment such as a reel that is often used outdoors, particularly an aluminum alloy outdoor component, is known in which an anodized surface is formed (for example, a patent document). 1).

JP 2003-166097 A

  In the conventional component body made of an aluminum alloy, since alumite is formed on the surface of the component body, the corrosion resistance can be improved. However, in the component main body in which such anodized aluminum is formed, for example, when the reel is dropped, the surface of the anodized aluminum is damaged and the component main body is exposed to a corrosive atmosphere, which may impair the corrosion resistance of the component main body.

  Therefore, it is conceivable to form a DLC (Diamond Like Carbon, diamond-like carbon) layer on the surface layer side of the alumite. Such a DLC layer generally has high hardness, wear resistance and slippery characteristics, so that even if the reel is dropped, the surface is hardly damaged, and thus the corrosion resistance of the component main body is kept high. it can.

  However, since the DLC layer is generally poorly reactive with anodized, that is, an aluminum oxide layer and has low adhesion, when the DLC layer is formed on the anodized, the DLC layer may be peeled off or the surface may be cracked. is there. When the DLC layer is peeled off, the corrosion resistance of the component main body is lowered, and sufficient hardness, wear resistance and slipperiness may not be obtained.

  An object of the present invention is to maintain high corrosion resistance, hardness, wear resistance, and slipperiness of a component body in an outdoor component.

  The outdoor component according to the first aspect of the present invention is an outdoor component used for fishing, and is a component main body made of aluminum alloy, an alumite layer formed by anodizing on the surface layer side of the component main body, and a surface layer side of the anodized layer An inclined layer in which a specific element is formed in an inclined shape by a plasma ion implantation process and a DLC layer formed by a plasma ion film forming process on the surface layer side of the inclined layer are provided.

  In this outdoor component, an alumite layer, an inclined layer, and a DLC layer are sequentially formed on a component body made of an aluminum alloy. The anodized layer is formed by anodizing which is anodizing. The inclined layer is formed by PBII (Plasma-Based Ion Implantation). The PBII method is a method of implanting ions by applying a high voltage pulse of at least minus 5 kV or more to a member placed in plasma. By such plasma ion implantation treatment, a part of the surface layer side of the alumite layer is modified to a new compound layer that cannot be obtained by thermochemical reaction, and the composition and function change from the surface layer side to the depth direction. An inclined inclined layer is formed. Then, a DLC layer is formed on the surface layer side of the inclined layer by PBID (Plasma-Based Ion Deposition). The PBID method is a film forming process performed simultaneously with the PBII method, and a DLC layer is formed on the surface layer side of the inclined layer by irradiating and depositing C ions.

  Here, a specific element is formed in an inclined shape by plasma ion implantation treatment between the anodized layer and the DLC layer, and has an inclined layer mixed with aluminum and carbon, so that the anodized layer and the DLC layer are in close contact with each other. Sexuality can be increased. Therefore, since the DLC layer is difficult to peel off, the corrosion resistance, hardness, wear resistance and slipperiness of the component main body can be maintained high.

  Further, as a conventional technique, there has been a method of forming a DLC layer at a high temperature of the component body in order to increase the adhesion between the alumite layer and the DLC layer. In this case, however, the component body is annealed. As a result, there is a problem that the strength of the component main body is remarkably lowered. However, in the outdoor part of the invention 1, since the inclined layer and the DLC layer are generally formed by the plasma ion implantation process and the plasma ion film forming process that do not require a high temperature of the component main body, The component main body is not annealed, so that the strength of the component main body can be prevented from decreasing.

  The outdoor component according to a second aspect is the outdoor component according to the first aspect, wherein the inclined layer is formed by a plasma ion implantation process of at least one of Si ions and C ions. In this case, since Si ions and C ions are ion-implanted with high energy, SiC, which is a new compound in which Si ions and C ions react, is generated in the gradient layer, and thus the alumite layer and the DLC layer The adhesion can be increased.

  The outdoor component according to the third aspect is the outdoor component according to the second aspect, wherein the amount of Si ions and C ions implanted is in the range of 10 at% or more of the total element concentration. In this case, by setting the implantation amount of Si ions and C ions to 10 at% or more, preferably 30 at% or more, the elements are distributed as if wedges are driven between the anodized layer and the DLC layer. Adhesion with the DLC layer can be further increased.

  The outdoor part according to the invention 4 is the outdoor part of the invention 2 or 3, wherein the implantation depth of Si ions and C ions into the alumite layer is in the range from 0.05 μm to 1.0 μm from the surface of the alumite layer. is there. In this case, for example, when the film thickness of the alumite layer is in the range of 0.5 μm to 3.0 μm, Si ions and C ions are implanted to a depth in the range of 0.05 μm to 1.0 μm from the surface of the alumite layer. By doing so, since a new compound is formed between the alumite layer and the DLC layer, the adhesion between the alumite layer and the DLC layer can be further increased.

  The outdoor component according to a fifth aspect of the present invention is the outdoor component according to any one of the first to fourth aspects, wherein the component main body is used for a fishing component used for fishing. In this case, in fishing parts that are often used in outdoor corrosive atmospheres, such as fishing reel reel bodies, spools, spool rings, line rollers, etc., the fishing parts have corrosion resistance, hardness, wear resistance, and slipperiness. Can be kept high.

  The outdoor component according to a sixth aspect of the present invention is the outdoor component according to any one of the first to fourth aspects, wherein the component main body is used for a bicycle component used in a bicycle. In this case, in bicycle parts that are often used in an outdoor corrosive atmosphere, such as bicycle cranks, rear derailleurs, brakes, etc., it is possible to maintain high corrosion resistance, hardness, wear resistance and slipperiness of the bicycle parts. it can.

  According to the present invention, in an outdoor component, on an aluminum alloy component main body, an alumite layer, an inclined layer made of a novel compound in which a specific element by the plasma ion implantation process is inclined, and a plasma ion film forming process Since the DLC layer is formed in order, the corrosion resistance, hardness, wear resistance and slipperiness of the component main body can be kept high.

  A dual-bearing reel employing an embodiment of the present invention is a low profile type reel for bait casting, as shown in FIGS. The dual-bearing reel includes an aluminum alloy reel main body 1 mounted on a fishing rod RD, a spool rotating handle assembly 2 disposed on the side of the reel main body 1, and a rotatable inside the reel main body 1. And a spool 4 for thread winding, which is detachably mounted. On the reel body 1 side of the handle assembly 2, a star drag 3 for drag adjustment is provided.

  As shown in FIGS. 1 and 2, the reel unit 1 includes a frame 5, a side cover 6 mounted on both sides of the frame 5, a front cover 7 that covers the front of the frame 5, and a thumb rest 8 that covers the top. And a rod mounting leg 9 (see FIG. 2) connected to the lower side of the frame 5 and mounted on the reel seat RS (see FIG. 2) of the fishing rod RD. Each member, spool 4 and reel sheet RS constituting the reel body 1 are made of an aluminum alloy, and the surface of each member is subjected to various surface treatments.

  Next, the surface structure of each member of the reel body 1 and the spool 4 will be described.

  As shown in FIG. 3, on the surface of the component main body 10 made of aluminum alloy of each member, anodizing 11 (see FIG. 3) formed by anodizing (S1 in FIG. 4) and plasma ions on the surface side of the anodizing 11 The inclined layer 12 (see FIG. 3) formed in an inclined shape by the implantation process (S2 in FIG. 4), and the DLC layer 13 formed in the surface layer side of the inclined layer 12 by the plasma ion film forming process (S3 in FIG. 4). (See FIG. 3). FIG. 3 is a schematic cross-sectional view for showing the surface structure of each member of the reel body 1 and the spool 4 and is different from the actual cross-sectional view.

  As shown in FIGS. 3 and 5, the alumite 11 is a transparent oxide film formed by anodizing of an aluminum alloy, and the aluminum alloy component body 10 is used as an anode in an electrolyte solution such as sulfuric acid. When electrolysis is performed, an oxide film is formed due to oxygen generated at the anode. The alumite 11 is formed by three steps of pretreatment such as degreasing, etching, and neutralization, anodizing treatment such as electrolytic treatment, and post-treatment such as sealing treatment.

  As shown in FIGS. 3 and 5, the graded layer 12 is formed by PBII (Plasma-Based Ion Implantation). The PBII method is a method in which ions are implanted by applying a high voltage pulse in a range of minus 5 kV to minus 30 kV to a member placed in plasma. In such a plasma ion implantation process, a part of the surface layer side of the alumite 11 shown in FIG. 3 is modified, and a specific element whose composition or function changes in the depth direction from the surface layer side is an inclined layer. 12 is formed.

  As shown in FIGS. 3 and 5, the inclined layer 12 is formed by plasma ion implantation treatment of Si ions and C ions. In the plasma ion implantation process, first, Si ions are implanted at a high output, and then C ions are implanted at a high output. At this time, since SiC is generated in the inclined layer 12, the adhesion between the alumite 11 and the DLC layer 13 can be increased. Further, as shown in FIG. 5, the amount of C ions implanted is larger than the amount of Si ions implanted, and the amount of Si ions and C ions implanted is 10 at% or more of the total element concentration, preferably 30 at% or more. It is a range. The element concentration is a value quantitatively analyzed by XPS (X-Ray Photoelectron Spectroscopy). As shown in FIG. 5, the Si ions and the C ions are inclined so that the injection amount decreases from the surface side (left side in FIG. 5) to the alumite 11 side (right side in FIG. 5). The film thickness of the alumite 11 is in the range of 0.5 μm or more and 3.0 μm or less, and the implantation depth of Si ions and C ions into the alumite 11 is 0.05 μm or more and 1.0 μm from the surface of the alumite 11. The range is as follows. FIG. 5 shows the relationship between the number of detected elements per time with respect to the depth direction from the surface measured by SIMS (Secondary Ion Mass Spectrometry, secondary ion mass spectrometer).

  As shown in FIGS. 3 and 5, the DLC layer 13 is formed by DLC (Diamond Like Carbon, diamond-like carbon) formed on the surface layer side of the gradient layer 12 by PBID (Plasma-Based Ion Deposition). ) Layer. The PBID method is a film forming process performed at the same time as the PBII method, in which C ions are implanted at a high output in the plasma ion implantation process and then deposited by irradiating the C ions at a low output to deposit on the surface layer side of the inclined layer 12. A DLC layer 13 is formed on the substrate.

  In such a surface structure of each member made of aluminum alloy constituting the reel body 1 and the spool 4, an inclined layer 12 is formed between the alumite 11 and the DLC layer 13 so as to be inclined by plasma ion implantation. Therefore, the adhesion between the alumite 11 and the DLC layer 13 can be increased. Therefore, since the DLC layer 13 becomes difficult to peel off, the corrosion resistance, hardness, wear resistance and slipperiness of the component main body 10 can be maintained high.
