Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to fishing equipment, fishing rods, reels, and other parts that come into contact with fishing lines, such as guide rings, line rings, line guides, line rollers, etc. (hereinafter referred to as guide rings, etc.). This relates to improving the slip properties, abrasion resistance, thermal conductivity, electrical conductivity, impact resistance, hardness, and longevity of threads.

[Conventional technology]

Parts that come into contact with the fishing line, such as guide rings, are coated with fine sand, salt, etc. due to the static electricity charged on the nylon thread, forming a long file-like structure that is rubbed, scraped, and grooved over and over again. Also, since the light itself is cut off, there will be problems with wear resistance unless it is very hard, so we have changed from conventional metal rings, agate rings, glass rings, magnetic rings, etc. to tungsten carbide rings and hard chrome rings. In addition, there has been a shift to alumina rings, zirconia rings, silicon nitride rings, silicon carbide rings, and other ceramic composite rings, which are harder, more slippery, and wear-resistant materials.

[Problem to be solved by the invention]

Conventional metal guide rings have excellent impact resistance, so there is no problem of them being damaged by contact with people when using them, and they are also highly conductive, discharging static electricity, and considerably preventing the adhesion of fine particles such as sand, salt, and dust. However, (a) the hardness is higher than that of ceramics (Tic).
, TiN, SiC), it is easily damaged by contact with threads and has poor abrasion resistance.(b) Compared to ceramics (SiC, etc.), it has a high coefficient of friction and poor slipperiness. There are problems such as the thread is very painful and breaks easily, (...) it lacks color and fashion as it is a cold color (TiN, etc.), silver luster color (TiC, etc.) or any other mixed color. .

Plastic guide rings and the like have the advantage of being light and inexpensive to manufacture, but on the other hand, they have problems with wear resistance and are easily damaged.

Next, there are the following problems with ceramic guide rings and the like.

The hardness of ceramics is At206 and Hv-2300~2
700, SiC Hv-2000~3000, ZrO2
Hv=1300~14-00.513N4 Hv=1
700~2700, Hv-2000~5 with TiC
000, TiN f T (v = 2000~3000
Although the hardness is high, the wear resistance does not improve much for the following reasons. As shown in Figure 1(b), the surface of the ceramic has microscopic pores, cranks, etc.
The corner 2 around the corner 2 has a sharp shape, and the force exerted by the fishing line easily causes minute damage.

As shown in FIG. 1(c), these micro-damages become large and become damaged micro-pieces 4 by adhering fine sand, salt, other fine particles, etc. due to static electricity during friction with the fishing line 3.

The broken small pieces 4 damage the fishing line 3, causing it to break, and also damage the surface of the guide ring, etc., resulting in serious wear.

In addition, ceramics are very susceptible to impact and often break when they hit hard objects such as rocks, so when installing guide rings etc., it is done by caulking to the frame, but the force of caulking at this time A considerable amount may be damaged.

Furthermore, some ceramics have low thermal conductivity, so fishing lines can be moved at speeds of 4. If you run it for 7 seconds, the fishing line (for example, nylon silver phosphorus No. 15) will melt and twist.

Furthermore, the colors of current ceramic materials are often plain, lacking gold, silver, and other luxurious and fashionable colors.

The purpose of this application is to provide a method for manufacturing guide rings and the like that improves abrasion resistance, prevents damage around pores, etc., and provides color fashionability at a low cost.

[Failure to solve the problem]

As a result of intensive research to achieve the above object, the inventor of the present invention has found that in order to prevent the corners around microscopic voids from becoming sharp and easily damaged, such as micropores and cracks scattered on the ceramic surface, The present invention was completed by discovering that abrasion resistance, impact resistance, and heat resistance can be improved by coating the area around the crack with metal or ceramic. It was also confirmed that by polishing away the corners of the coating and reinforcing and retaining only the defective areas around the crank, it was possible to correct the defects while retaining the characteristics of the base material.

In short, the gist of the first invention is a method for manufacturing a fishing part whose base material is made of ceramics, characterized in that at least the surface in contact with the fishing line is coated with metal or ceramics. The second invention is characterized in that in a fishing component whose base material is ceramic, at least the contact surface with the fishing line is coated with metal or ceramic, and then only the surface layer is physically or chemically removed. There is a manufacturing method for different fishing parts.

As the base material ceramic used in the present invention, all ceramics that are normally used as parts can be used, but in particular, TiN, various ceramics containing TiN, TiC, αSiC, βSiC, high-purity alumina,
Alumina, BeO9CrO2Mgo, SiO2 (silica), 5102 (quartz), silica glass, TiO2゜crystal glass, ZrO2 (cubic crystal), monoclinic zirconia, mullite, spinel, cordierite, B4C

WC, S i 3N4. Sintered bodies such as glass, Aba, alumina porcelain, porcelain, agate, sialon, and other ceramic composite materials are preferred.

By the way, the corners around the microscopic voids such as micropores and cracks scattered on the ceramic surface are very prone to breakage, and the broken powder at this time becomes the cause of the next full-scale breakage. In the present invention, as shown in FIG. 1(a), a ceramic base material 6 is coated with a coating film 5 made of metal or ceramics.

This will eliminate pores and cracks.

It is possible to coat and fill with a metal such as t + Cu or Fe to make it adhere and hold, firmly reinforcing the periphery, reducing micro-destructive wear due to the force exerted by the fishing line, and improving wear resistance.

The coating method is based on the ceramics to be coated,
The CVD method, PVD method, thermal spraying method, etc. are appropriately selected in consideration of the suitability of the metal. For example, Ti, Cr, TiN.

TiC, etc. can be processed using the direct current method, high frequency method, cluster ion beam method, hot cathode method, ARE method, plasma electron beam method (HC

(Physical Vapor Deposit
on) method is preferred. In addition, ceramics such as SiC can be processed using CVD (Chemical
The al VaporDeposition method or the ion silating method is preferred.

Other effects can be added to the coating material by utilizing its properties.

For example, TiN, Tic, Ti, Cr, etc. are imparted with electrical conductivity and can prevent the adhesion of broken particles due to electrostatic charging to the fishing line, thereby significantly improving wear resistance.

Furthermore, since SjC and the like have high thermal conductivity, it is possible to prevent the fishing line from breaking due to its frictional heat.

Further, in order to impart a color fantasy, it is preferable to coat the surface of a plain ceramic base material with TjN (gold color), TiC (silver color), etc., or a mixture of these colors appropriately selected or mixed.

The number of coatings in the present invention is not limited to one type or one layer, and of course may be two or more types or two or more layers. For example, TiN and Ti are added to SiC films for the purpose of improving hardness, wear resistance, thermal conductivity, electrical conductivity, slipperiness, decorative properties, etc.
There are also methods of use such as attaching a C film, attaching a TiN or SiC film to a TiC film, or using a combination of metals such as Ti and Cr.

In addition, the coating of the present invention reduces frictional resistance and heat generation when it comes into contact with the fishing line 3 by forming a layer of the coating film 5 with undulations as shown in FIG. It can extend the lifespan of etc.

Furthermore, in the present invention, if the purpose is only to retain and reinforce defects such as pores or cracks on the surface, as shown in FIG. Remove surface defects by physical or chemical methods such as lamps or polishing]
If only the voids are filled, the properties of the base material can be utilized as is, and only the defective parts can be reinforced.

Note that if the thickness of the coating film is less than 0.1 μm, the coating will not be uniform due to unevenness of the background.
The preferred size is μm or more. Also, if the roughness of the coating film is too large, it will seriously damage the fishing line.
SBO601) or less is preferable.
