一种非晶合金发箍圈及发箍及其制造方法
摘要：
本发明涉及非晶合金的应用技术领域，特别是涉及一种非晶合金发箍圈及发箍及其制造方法，该发箍圈是采用锆基非晶合金、铜基非晶合金、钛基非晶合金、镍基非晶合金、钯基非晶合金或铁基非晶合金而制造的非晶合金发箍圈。该发箍圈的维氏硬度为400~600，降伏强度为1000~3000MPa，弹性限度为2~3%，镍释放量为0~0.015mg/cm2/week，经500~2000小时的盐雾测试后其表面无腐蚀。非晶合金发箍圈的制造方法，先通过压铸成型法制备预成型件；再通过TPF或RDF对预成型件进行二次成型，得到非晶合金发箍圈。该非晶合金发箍圈具有高弹性、高强度、高硬度、韧性好、耐刮、耐磨、抗腐蚀和高精密度的优点。
摘要（英）：

The invention relates to the technical field of application of amorphous alloys and particularly relates to an amorphous alloy hair clasp ring and a hair clasp and a manufacturing method thereof. The hair clasp ring is the amorphous alloy hair clasp ring which is manufactured by a zirconium-based amorphous alloy, a copper-based amorphous alloy, a titanium-based amorphous alloy, a nickel-based amorphous alloy, a palladium-based amorphous alloy or a ferrum-based amorphous alloy. The Vickers hardness of the hair clasp ring is 400-600, the yield strength of the hair clasp ring is 1000-3000MPa, the elastic limit is 2-3% and the nickel release is 0-0.015mg/cm<2>/week, and the surface of the alloy is not corroded after a salt spray test within 500-2000 hours. The manufacturing method of the amorphous alloy hair clasp ring comprises the following steps: firstly preparing a preform by virtue of a die-cast formation method; and then secondarily forming the preform by using TPF or RDF to obtain the amorphous alloy hair clasp ring. The amorphous alloy hair clasp ring has the advantages of being high in elasticity, strength and hardness, good in toughness, scratch resistant, wear resistant and corrosion resistant and high in precision.
