钛镍合金

借助流化沙浴实现镍钛合金热定型个#Cole-Parmer沙浴用于人体心脏支架工艺#镍钛合金是一种形状记忆合金，能将自身的塑性变形在某一特定温度下自动恢复为原始形状的特种合金，具有良好的可塑性，又称热定型能力，被广泛应用于多个领域包括医疗器械、航空航天、电子等领域。在医疗领域中，镍钛诺可以用于制造支架、人体植入设备，导丝、取石篮、过滤器、针头、牙科锉刀和其他手术器械。高纯度原料和熔融方法可以确保取得均匀的最终产品。行业常采用不同的热处理加工方法来实现最终产品成型。Cole-Parmer系列流化沙浴能够覆盖温度范围从-100°C到700°C的应用，因在超高温度下也能保持温度稳定性和均一性，并且保证温度精密，是镍钛诺热处理的理想选择。✦ ++Cole-Parmer流化沙浴床应用✦ +► 镍钛合金热处理热处理常用于设定镍钛合金的最终形状。如果镍钛合金有合理的冷加工量（大约30%或更多），400℃到 500℃的温度和适当的停留时间将产生一个直的、扁平的或成型的零件。术语“形状设置”通常用于此过程，成型零件是使用定制夹具创建的。一些常见的热处理方法是钢绞线退火（用于直线和管材）、箱式炉、熔盐浴和流化沙浴床。热处理的另一个目的是确定镍钛合金的最终机械性能和转变温度。材料经过冷加工后，适当的热处理将在材料中建立可能的最佳形状记忆或超弹性性能，同时保留足够的残余冷加工效果以抵抗循环过程中的永久变形。► 镍钛合金热处理的难点解决面临的难点：高温情况下的温度均一性合金的热处理需要在一个特定的稳定高温环境下进行，若是温度过高会导致产品的弹性功能丧失，而温度过低则会导致产品没有成功的坚硬化，不利于后期的使用处理难点解决：Cole-Parmer流化沙浴床可以在700℃的温度条件下，提供一个最高±0.01℃的高温环境浴，可以帮助客户轻松地完成各种温度条件下的高温热处理。Cole-Parmer流化沙浴床工作中► Cole-Parmer流化沙浴床更多应用推荐基本通用款高温度稳定性高流量清洗款1、温度探头校准—不规则形状传感器2、聚合物清洁快速清洗，限度地减少昂贵的生产设备停机时间，只需要烘箱1/3时间无刀具损伤、钢丝擦刷、刮伤损坏无人值守清洗，降低了劳动成本不会腐蚀磨料模具轻松处理断路板、模具、喷嘴及其他模具材料的小孔沙浴流化床的能源效率无需耗材、溶剂或任何其他有害的化学物质去除几乎所有的塑料，如PVC、PET、Flouropolymers和PEEK聚合物3、恒温加热—替代水浴盐浴等4、材料热处理—镍钛合金等
