ど〕、更に使用は拡大すると予想されている。2. Description of the Related Art Conventionally, wire ropes are frequently used for mooring marine floating rafts such as oyster cultivation rafts and fish cultivation rafts as shown in FIG. In this case, a plated wire rope is usually used because it is immersed in seawater for a long time. In the figures, 1 is the seabed, 2 is the sand and mud, 3 is the raft, 4 is the bladder, 5 is the mooring rope, 6 is the anchor, and 7 is the oyster. Conventionally, as a plating of the wire rope, a hot-dip Zn thick plating product having an adhesion amount of 300 g / m2 or more has been used. In recent years, however, a Zn-5 to 10% Al hot-dip wire rope having excellent corrosion resistance has been used. The conversion is underway. It is said that Zn-5 to 10% Al hot-dip plating is about 2 to 4 times more excellent in corrosion resistance than hot-dip Zn plating [L. A. Rocha: Corrosion Vol 47
July 1991 P536, Sangyo Shimbun March 23, 1999, etc.], and its use is expected to expand further.

市場ニーズには十分耐え得るデータが示されている。There are many demands for guaranteeing the life of a wire rope for mooring an ocean floating raft in seawater for about four years (35,000 hours). In the case of Zn-5 to 10% Al hot-dip coating on wire rope with a coating weight of 300 g / m2 or more, in the 5% Nacl salt spray test specified in JISZ2371, red rust occurs in 4 years and corrosion progresses However, there is no evidence that the wire is damaged by corrosion due to corrosion, and the wire is not broken, indicating data that can sufficiently withstand the market needs for the above four years.

を目的とする。On the other hand, in the actual marine raft shown in FIG. 1, since the sand and mud move near the boundary of the sand and mud shown in part A due to the flow of sea water such as waves and ocean currents, the sand and mud move in addition to the seawater corrosion. Erosion phenomenon (a phenomenon in which metal is physically worn by flowing environmental substances such as water and sand) occurs. This erosion phenomenon often occurs at a height of 3 m above and below part A. For this reason, the wire rope wears more rapidly than when it is simply immersed in seawater, and the wire rope strand breaks frequently in only a few years in Fig. 1A, requiring replacement with a new one. I can't meet it. Therefore, for example, the life as a mooring line of a hot-dip Zn-plated wire rope and a Zn-5% Al-plated wire rope having the same adhesion amount is not greatly different, and not only is the characteristic of Zn-5% Al high corrosion resistant plating not utilized, Rather, there is a situation in which less expensive hot-dip Zn plating is more advantageous in total. Therefore, unless such an erosion countermeasure is taken, it is considered that the practical development of the highly corrosion-resistant plated wire rope becomes difficult. The present invention has been made in view of the above points, and has been made to reduce the erosion erosion of a plated wire rope due to flowing seawater or sand mud, thereby prolonging the life of the wire rope for mooring an ocean floating raft. An object of the present invention is to provide a mooring wire rope having excellent properties.

ン特性について説明する。In order to achieve the above object, the present invention provides a mooring rope for mooring an ocean floating raft, which has been subjected to soft plating such as Zn or Zn-Al. 20m on the surface of the plated wire rope 3m above and below the seawater boundary
By applying a wear-resistant coating with a thickness of ~ 500 µm, resistance to erosion erosion due to the coexistence of corrosion and sand / mud wear is improved. Therefore, this wear-resistant coating is manufactured by variously adjusting the length from the anchor end to the coating portion according to the thickness of the sandy mud layer on the sea floor at the place where the floating raft is installed. Further, it is effective that the wear-resistant coating is performed by spraying Al 2 O 3 onto a wire rope. Hereinafter, the erosion characteristics in the present invention will be described by erosion tests of various types of plated wire ropes provided with a wear-resistant coating.

ージョン（侵食）特性を測ることが可能になる。FIG. 2 shows a system diagram of an erosion test apparatus. The solution to be used is a 5% NaCl aqueous solution. Zirconia sand (ZrO 2 particles) having an average particle size of 0.5 μm is suspended and suspended in the aqueous solution, and the liquid L is attached to a transparent plastic pipe 16 via a sealing agent 17. A wire is caused to flow through the wire rope 15 at a flow rate of 36 m / min, and the time until red rust appears on the wire rope 15 is examined in the red rust occurrence observation unit 18. In the figure, the bottoms of the upper and lower tanks 12 and 11 are adapted to blow air from below as shown by 13, thereby generating bubbling 14 in the liquid L to prevent zirconia sand from depositing. With such an apparatus, it becomes possible to measure the erosion (erosion) characteristics in which corrosion by 5% NaCl aqueous solution and wear by zirconia sand occur simultaneously.

た。In FIG. 3, the time until the occurrence of red rust measured on various types of plated wire ropes using the apparatus shown in FIG. 2 is displayed, and the corrosion resistance and erosion characteristics of the wire ropes are compared. As is clear from FIG. 3, the Zn-Al plating rope has a much higher corrosion resistance in the salt spray test than the Zn plating rope, but is almost equivalent to Zn plating for erosion (erosion). Does not exhibit the characteristics of high corrosion resistance plating. This is Zn for hard sand wear
This is probably because Zn-Al plating is almost as soft and has low resistance. FIG. 3 (right) also shows the result of applying a coating having excellent wear resistance to the surface of such a soft plated rope. In this figure, alumina (Al 2 O 3 ) was coated by thermal spraying as a wear-resistant coating.

ジョン特性は向上しないことが判った。As is clear from FIG. 3, regardless of the type of plating, when the coating layer thickness is 20 μm or more, the red rust generation time of the rope outer layer wire increases linearly, and the thicker the coating, the lower the erosion resistance. It turns out that it improves. If it is less than 20 μm, there will be many holes in the coating,
Also, since the coating does not completely cover the plating,
It was found that the seawater locally penetrated directly below the coating and melted the plating, so that the wear-resistant film dropped off early, and as a result, the erosion characteristics were not improved.

It is clearly recognized that excellent mooring wire ropes can be made. Also, when the thickness exceeds 500 μm, the coating layer cracks due to bending and a part of the coating falls off, the time until red rust generation becomes shorter than without bending, and the effect is small compared to the cost increase. It is clear that the coating thickness is limited to a maximum of 500 μm.
