問題があった。However, under the harsh operating conditions in today's spinning mills, especially when the spindle rotation speed is 25.0OOr, p, m or more, A1□0
Rings made of SiC are brittle, so if they continue to slide with the traveler for a long time, cracks will develop on the ring surface, causing the ring to break and peel, and the wear of the traveler will increase. However, due to friction between the ring travelers, the contact point becomes locally high temperature, and the iron (Fe) of the traveler reacts with the Si of the ring, causing abnormal wear of the traveler and welding of the ring, resulting in disordered spinning. there were.

供するものである。(Means for Solving the Problems) In order to solve the above problems and obtain a spinning machine ring with excellent wear resistance and sliding characteristics, the surface of the spinning machine ring that comes into contact with at least the traveler is coated with SiC whiskers. A1□0. The present invention provides a ring for a spinning machine formed by the above method.
本発明の対象となる紡機用リングは、通常紡機用として
適用されるものであれば特に制限されるものでなく、例
えばシングルフランジリング、縦形リング、コニカル形
リング等に適用することができる。The ring for a spinning machine to which the present invention is applied is not particularly limited as long as it is normally applied to a spinning machine, and can be applied to, for example, a single flange ring, a vertical ring, a conical ring, etc.

る。These are conventionally known spinning machine rings made of carbon steel or iron-based sintered crystal, and at least the flange portion that comes into contact with the traveler is S
It is made of Alz○3 with iC whiskers dispersed therein, and is formed by fitting or adhering to the body, but a molded body formed by integrally molding the entire ring for a spinning machine and firing it may also be used.

８μｍが良く、０．４μｍ未満ではウィスカの価格が高
くなり、またウィスカの強度が小さくなる。０．８μｍ
を超えると、添加量に対するウィスカの表面積が小さく
なり、ウィスカの効果が発揮できなくなる。At least the part of the spinning machine ring that comes into contact with the traveler is S.
It is formed of A1°03 with 20-40% of iC whiskers dispersed therein, and the diameter of the SiC whiskers is 0.4-0.
8 μm is preferable; if it is less than 0.4 μm, the cost of the whisker will be high and the strength of the whisker will be low. 0.8μm
If it exceeds the amount, the surface area of the whiskers becomes small relative to the amount added, and the whiskers cannot exhibit their effects.

視できなくなると共に焼結がしにくくなる。The amount of SiC whiskers added is preferably 20 to 40%, and 2
If it is less than 0%, there will be no whisker effect, and if it exceeds 40%, there will be too many whiskers, and the balance with the AIto3 matrix will be lost, and the reaction of SiC with Fe by St will not be negligible, and sintering will become difficult.

散性が悪くなる。The length of the whisker is preferably 10 to 80 μm. If the length is less than 10 μm, the whisker will be easily pulled out from the matrix and will have little effect on preventing crack growth. Dispersibility deteriorates.

ウィスカを分散させることにより靭性を向上させること
ができるものである。The A1.03 matrix is hard and does not easily react with the Fe of the traveler, so it is difficult to weld with the traveler.
SiC has low toughness and has the drawback of cracking and peeling due to repeated sliding movements of the traveler.
Toughness can be improved by dispersing whiskers.

られる。In other words, the whiskers act like a bridge between the cracks behind the tip of the crank, preventing the crank from widening, and the whiskers bend the direction of crack propagation from the direction perpendicular to the tensile stress, causing the crank to Since the propagation direction of the crack is diverted from the direction perpendicular to the tensile stress, the propagation of cracks is suppressed. Furthermore, when the crank passes across the whiskers, the energy required for the crank to advance increases by the amount of work required to pull the whiskers out of the matrix, so toughness is improved. In addition, the whiskers suppress the growth of crystal grains of Al20.03 in the matrix during sintering. The structure of AlzOz becomes fine, and the grain size of AlzOz is usually suppressed to an average of 1 to 3 μm.
（実施例） 以下本発明を実施例に基づいて説明する。(Example) The present invention will be explained below based on examples.
