Description

一种高熵合金在滑雪器材中的用途 技术领域
本申请涉及高熵合金材料的应用技术领域，更具体地涉及一种高熵合金在滑雪器材中的用途。
背景技术
随着人们生活品质的提高，越来越多的年轻人会尝试并热衷于户外运动，如轮滑、滑板、滑板车、滑雪等，既能锻炼身体，又能达到很好的社交目的。这些户外运动中，滑雪运动对人员和场地的要求很好，相对小众，但作为一种高档运动，其对年轻人的吸引也越来越大。
滑雪板是滑雪运动中必须使用的运动设备，一般分为高山板、越野冬季两项板、跳台板、自由式板、单板等，种类较多。一般而言，滑雪板包括具有底部部件的板，底部部件是滑雪板的下面部分，也是接触雪面的部分，不仅需要较高耐磨性，也得需要较低的摩擦系数。目前，大多是底座是塑料或木材材料制作的，有两种制备方式：一种是融塑工艺，另一种是挤压式工艺，融塑工艺制备的底部寿命长，容易维修，但是融塑工艺制得的滑雪板速度最慢，上蜡量最小。挤压式工艺制得的滑雪板正好相反，压缩板比融塑板更好，更结实，更快，上蜡好，但是制备工艺复杂，格昂贵，不宜维修。
2004中期，研究学者跳出传统合金的发展框架，提出新的合金设计理念，即多主元高熵合金。其就是多种元素为主元，主要元素五种及以上，其中每种主要元素的原子百分比介于5～35％之间，任何一种元素在原子百分比上不会超过50％而成为主要元素。高熵合金具有一些传统合金所无法比拟的优异性能，如高强度、高硬度、高耐磨耐腐蚀性、高热阻、高电阻等，常被用于电子材料。然发明人发现，高熵合金在用于滑雪板或滑雪用的交通工具中，体现超良好的 速度，只需更少的能量即可驱动，具有相当好的节能效果，且由于处于低温环境下，高熵合金材料的强度越佳，故而，高熵合金在滑雪器材中具有广阔的应用前景。
申请内容
为了解决上述缺陷，本申请提供一种高熵合金在滑雪器材中的用途。
较佳的，滑雪器材包括本体部及位于该本体部底部的底部部件，高熵合金用于滑雪器材的底部部件。
较佳的，高熵合金用于滑雪板的底部部件。
较佳的，高熵合金用于冰刀鞋的冰刀。
较佳的，高熵合金用于滑雪车的底部部件。
较佳的，所述高熵合金为AlNiCuZrFeCr及其组成的高熵合金；或AlCoCrFeNi及其组成的高熵合金。
较佳的，所述高熵合金为铸态高熵合金、单晶态高熵合金或纤维薄板态高熵合金。发明人发现，纤维薄板态高熵合金应用于滑雪器材中时，可轻易地弯折成卷而不发生任何的机械破坏，尤其适合作为含拱形头的底部部件，不仅具有超级良好的摩擦系数，而且柔韧性优良，具有优秀的弯折加工性能，更易形成拱形头，降低加工成本，提高底部部件的质量。
本申请的有益效果是：
采用高熵合金制备滑雪器材，使得滑雪器材具有较小的摩擦系数，体现超良好的速度，只需更少的能量即可驱动，具有相当好的节能效果；
滑雪器材的使用环境温度比较低，在低温环境下，高熵合金材料的强度越佳，从而提高滑雪器材的耐磨耐撞性；
纤维薄板态高熵合金应用于滑雪器材中时，可轻易地弯折成卷而不发生任何的机械破坏，尤其适合作为含拱形头的底部部件，不仅具有超级良好的摩擦系数，而且柔韧性优良，具有优秀的弯折加工性能，更易形成拱形头，降低加工成本，提高底部部件的质量。
具体实施方式
下面将结合本申请的实施例，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请公开了一种高熵合金在滑雪器材中的用途。采用高熵合金材质制备的滑雪器材可提高其在雪地的滑行速度，且具有较好的强度，减少维修成本。同时，还由于高熵合金的韧性较好，使得滑雪器材的加工工艺更为简单。优选地，滑雪器材包括本体部及位于该本体部底部的底部部件，高熵合金用于滑雪器材的底部部件。需要说明的是，底部部件是指与雪地接触的部件。将高熵合金材质制备的底部部件设于本体部的底部，有效的节省高熵合金材质的用料，同时又可实现上述优良效果。
滑雪器材可为但不限于滑雪板、冰刀鞋和滑雪车等可于雪上滑行的工具。一实施例中，高熵合金用于滑雪板的底部部件，制备成薄板结构，该厚度可为但不限于0.5mm-1.5mm。另一实施例中，高熵合金用于冰刀鞋的冰刀。有的实施例中，高熵合金用于滑雪车的底部部件。

表1温度为-5℃、-10℃和-15℃的摩擦系数的测定
Figure PCTCN2021070864-appb-000001
从表1的数据可知，本申请采用高熵合金制备滑雪器材，其摩擦系数小于对比例1-2，故而，高熵合金用于滑雪器材可使其具有较小的摩擦系数，体现超良好的速度，只需更少的能量即可驱动，具有相当好的节能效果。且随温度降 低，摩擦系数不增反而降，高熵合金在滑雪器材中具有广阔的应用前景。
