Description

DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS

[0017] The present invention will be described with reference to the specific embodiments.

[0018] The present invention discloses the application of the high-entropy alloy in skiing equipment. The skiing equipment made of the high-entropy alloy can increase its sliding speed in the snow, and has high strength and reduces maintenance costs. Moreover, due to better toughness of the high-entropy alloy, the processing technology of the skiing equipment is simpler. Preferably, the skiing equipment includes an equipment body and a bottom member disposed on the bottom of the equipment body, and a high-entropy alloy is used for manufacturing the bottom member of the skiing equipment. The bottom member refers to the part in contact with the snow. The bottom member made of the high-entropy alloy is only arranged at the bottom of the equipment body, which not only achieves the above-mentioned excellent effects, but also effectively saves high-entropy alloy material.

[0019] The skiing equipment may be, but is not limited to, skis, ice skate shoes, and skiing vehicles that can slide on snow. In one embodiment, the high-entropy alloy is used for the bottom member of the ski by preparing a plate structure, and the thickness of the plate structure may be, but not limited to, 0.5 mm-1.5 mm. In another embodiment, the high-entropy alloy is used for a blade of the ice skate shoe. In other embodiments, the high-entropy alloy is used for a bottom member of the ski vehicle.

[0020] The high-entropy alloy may be, but is not limited to, AlNiCuZrFeCr and its high-entropy alloy, or AlCoCrFeNi and its high-entropy alloy. Further, the high-entropy alloy is the as-cast high-entropy alloy, the single-crystal high-entropy alloy, or the fiber-state high-entropy alloy. The inventor found that when the fiber-state high-entropy alloy is used in skiing equipment, the skiing equipment can be easily bent and further rolled up without any mechanical damage, and the fiber-state high-entropy alloy is particularly suitable for the bottom member having an arched structure, which not only has a good friction coefficient, but also has excellent flexibility and processing performance. It is easy to form the arched structure, reduce costs, and improve the quality of the bottom member.

[0021] The following embodiments are for further describing the process of manufacturing skiing equipment using a high-entropy alloy.

EXAMPLE 1

[0022] A ski is prepared. The ski includes an equipment body, a bottom member, and a ski core located between the equipment body and the bottom member, and the bottom member is arranged below the ski core. The bottom member is made of Al.sub.0.3CoCrFeNi high-entropy alloy and the thickness of the bottom member is 1 mm.

EXAMPLE 2

[0023] An ice skate shoe is prepared. The ice skate shoe includes a shoe body and a blade located at the bottom of the shoe body. The ice skate shoe is made of Al.sub.0.3CoCrFeNi high-entropy alloy.

Comparative Example 1

[0024] The ski is prepared. The ski includes an equipment body, a bottom member, and a ski core located between the equipment body and the bottom member, and the bottom member is arranged below the ski core. The bottom member is made of wood by extrusion and the thickness of the bottom member is 1 mm.

Comparative Example 2

[0025] The ice skate shoe is prepared. The ice skate shoe includes a shoe body and a blade located at the bottom of the shoe body. The ice skate shoe is made of stainless steel.

[0026] The friction coefficients of the skis and ice skate shoes in Examples 1-2 and Comparative Examples 1-2 at temperatures of -5° C., -10° C. and -15° C. were tested, as shown in Table 1.

TABLE-US-00001 TABLE 1 Friction Friction Friction coefficient coefficient coefficient Examples (−5° C.) (−10° C.) (−15° C.) Example 1 0.042 0.040 0.039 Example 2 0.035 0.033 0.032 Comparative Example 1 0.113 0.110 0.118 Comparative Example 2 0.107 0.106 0.109

[0027] It can be seen from the Table 1 that the present invention uses the high-entropy alloy to prepare skiing equipment, and friction coefficients of the Examples 1-2 are less than that of Comparative Examples 1-2. Therefore, the use of high-entropy alloy in skiing equipment can make the skiing equipment have a smaller friction coefficient and obtain better speed, so the skiing equipment can be driven with less energy and can save energy. Furthermore, as the temperature decreases, the friction coefficient does not increase but decreases. High-entropy alloy has broad application prospects in skiing equipment.

[0028] While the invention has been described in connection with what are presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
