本発明は、釣り糸用ガイド部材に関するものである。   The present invention relates to a fishing line guide member.

一般に、釣り竿に取り付けられる釣り糸用ガイドは硬質な釣り糸用ガイド部材、いわゆる導糸環と、釣り糸用ガイド部材を内周部に嵌合することが可能な形状の保持部と、釣り糸用ガイドを釣り竿へ取り付けるための取り付け部とから構成される。そして、釣り糸用ガイド部材は、リールから引き出された釣り糸を挿通して案内することができるように、リング状に形成され、特に、耐磨耗性が求められる釣り糸用ガイド部材には、セラミックスが適用されている。   In general, a fishing line guide attached to a fishing rod includes a rigid fishing line guide member, a so-called yarn introduction ring, a holding portion having a shape capable of fitting the fishing line guide member to the inner periphery, and a fishing line guide. It is comprised from the attachment part for attaching to. The fishing line guide member is formed in a ring shape so that the fishing line drawn from the reel can be inserted and guided. In particular, the fishing line guide member that requires wear resistance is made of ceramic. Has been applied.

このような、セラミックスからなる釣り糸用ガイド部材として、例えば特許文献1では、炭化珪素を主成分とするセラミックスの表面に釣糸の案内面を形成してなり、該案内面近傍部に気孔を有し、各気孔の間は滑らかな平坦面となり、内部は気孔が実質的に存在しない緻密なセラミックスからなる釣り糸用ガイド部材が提案されている。   As such a fishing line guide member made of ceramics, for example, in Patent Document 1, a fishing line guide surface is formed on the surface of ceramics mainly composed of silicon carbide, and there are pores in the vicinity of the guide surface. There has been proposed a fishing line guide member made of dense ceramics having a smooth flat surface between the pores and substantially no pores inside.

特許第3540912号公報Japanese Patent No. 3540912

釣り竿を倒したり落としたりしたときに加わる衝撃によって釣り糸用ガイド部材に破損が生じると釣りが行なえなくなることから、今般の釣り糸用ガイドには、耐衝撃性の向上が求められている。   Since fishing cannot be performed if the fishing line guide member is damaged by the impact applied when the fishing rod is tilted or dropped, the fishing line guide is required to have improved impact resistance.

本発明は、上記要求満たすべく案出されたものであり、耐衝撃性に優れた釣り糸用ガイド部材を提供することを目的とする。   The present invention has been devised to satisfy the above requirements, and an object thereof is to provide a fishing line guide member having excellent impact resistance.

本発明の釣り糸用ガイド部材は、炭化珪素の結晶多形が、4H型、6H型および15R型からなる炭化珪素質焼結体であって、前記4H型、前記6H型および前記15R型の質量の合計100質量%のうち、前記6H型が30質量%以上48.5質量%以下であり、前記15R型が
1質量%以上7質量%以下であり、残部が4H型であるとともに、Alが固溶した炭化珪素結晶を含むことを特徴とするものである。
The fishing line guide member of the present invention is a silicon carbide based sintered body in which the silicon carbide crystal polymorph is a 4H type, a 6H type, and a 15R type, and the masses of the 4H type, the 6H type, and the 15R type are as follows. Of the total 100% by mass, the 6H type is 30% by mass or more and 48.5% by mass or less, the 15R type is 1% by mass or more and 7% by mass or less, the remainder is 4H type, and Al is in solid solution. The silicon carbide crystal is included.

本発明の釣り糸用ガイド部材は、破壊靱性が高く、耐衝撃性に優れているため、釣り竿を倒したり落としたりしたときに加わる衝撃によっても破損が生じにくい。   Since the fishing line guide member of the present invention has high fracture toughness and excellent impact resistance, the fishing line guide member is not easily damaged by an impact applied when the fishing rod is tilted or dropped.

本実施形態の釣り糸用ガイド部材の耐磨耗性の評価に用いる耐磨耗性評価装置の構成の一例を示す概略図である。It is the schematic which shows an example of a structure of the abrasion-resistant evaluation apparatus used for abrasion resistance evaluation of the guide member for fishing lines of this embodiment.

以下、本実施形態の釣り糸用ガイド部材について説明する。   Hereinafter, the fishing line guide member of the present embodiment will be described.

本実施形態の釣り糸用ガイド部材は、炭化珪素の結晶多形が、4H型、6H型および15R型からなる炭化珪素質焼結体であって、4H型、6H型および15R型の質量の合計100
質量%のうち、6H型が30質量%以上48.5質量%以下であり、15R型が1質量%以上6質量%以下であり、残部が4H型であるとともに、Alが固溶した炭化珪素結晶を含む。炭化珪素の結晶多形が上述した範囲であることにより、破壊靱性が高く、耐衝撃性に優れているため、釣り竿を倒したり落としたりしたときに加わる衝撃によっても傷や破損が生じにくい。
The fishing line guide member of the present embodiment is a silicon carbide based sintered body in which the silicon carbide crystal polymorph is composed of 4H type, 6H type and 15R type, and the total mass of 4H type, 6H type and 15R type 100
Of the mass%, 6H type is 30% by mass or more and 48.5% by mass or less, 15R type is 1% by mass or more and 6% by mass or less, and the balance is 4H type, and a silicon carbide crystal in which Al is solid-solved Including. Since the silicon carbide crystal polymorph is in the above-described range, the fracture toughness is high and the impact resistance is excellent. Therefore, even when the fishing rod is tilted or dropped, scratches or breakage hardly occur.

このように、破壊靱性が高く、耐衝撃性に優れたものとなるのは、後の製造方法に詳細は記載するが、出発原料としてアルミナ粉末を添加し、成形体をカーボン粉末で覆って焼成すると、焼結体において、Alが固溶した炭化珪素結晶が確認されるとともに、出発原料の炭化珪素粉末の結晶多形から、6H型および15R型が減少し4H型が著しく増加する。そのため、増加した4H型の結晶多形の炭化珪素結晶は、Alが固溶した炭化珪素結晶であると考えられ、増加した4H型の結晶多形の炭化珪素結晶、すなわち、Alが固溶した炭化珪素結晶の存在によって、亀裂による強度低下に対する抵抗力が高まり、耐衝撃性に優れたものとなるものと考えられる。   As described in detail in the later manufacturing method, the fracture toughness is excellent and the impact resistance is excellent. However, alumina powder is added as a starting material, and the compact is covered with carbon powder and fired. Then, in the sintered body, silicon carbide crystals in which Al is dissolved are confirmed, and from the polymorph of the silicon carbide powder as a starting material, the 6H type and the 15R type are reduced and the 4H type is remarkably increased. Therefore, the increased 4H type polymorphic silicon carbide crystal is considered to be a silicon carbide crystal in which Al is dissolved, and the increased 4H type polymorphous silicon carbide crystal, that is, Al is dissolved. The presence of silicon carbide crystals increases resistance to strength reduction due to cracks, and is considered to be excellent in impact resistance.

When other crystals are present, the total mass of the crystal polymorphs of silicon carbide may be used as the denominator, and the mass of each crystal polymorph may be expressed as a numerator.

また、Alが固溶した炭化珪素結晶については、電子線マイクロアナライザー(EPMA)による面分析から得られたカラーマッピングで確認することができる。具体的には、珪素(Si)、炭素(C)、アルミニウム(Al)の面分析から得られたカラーマッピングを基に、珪素(Si)および炭素(C)が重複する領域に、アルミニウム(Al)が確認されれば、Alが固溶した炭化珪素結晶を含んでいるとみなすことができる。   In addition, the silicon carbide crystal in which Al is dissolved can be confirmed by color mapping obtained from surface analysis using an electron beam microanalyzer (EPMA). Specifically, based on the color mapping obtained from the surface analysis of silicon (Si), carbon (C), and aluminum (Al), aluminum (Al) is formed in a region where silicon (Si) and carbon (C) overlap. ) Is confirmed, it can be regarded as containing silicon carbide crystals in which Al is dissolved.
