Description

高阻尼形状记忆合金
技术领域
本发明涉及一种高阻尼形状记忆合金。
背景技术
有一种特殊的金属材料,经适当的热处理后即具有回复形状的能力,这种材料被称为形状记忆合金(ShapeMemoryAlloy,简称为SMA),这种能力亦称为形状记忆效(ShapeMemoryEffect,简称为SME)。通常,SMA低温时因外加应力产生塑性变形,温度升高后,克服塑性变形回复到所记忆的形状。研究表明,很多合金材料都具有SME,但只有在形状变化过程中产生较大回复应变和较大形状回复力的,才具有利用价值。到目前为止,应用得最多的是NiTi合金和铜基合金。
发明内容
本发明提供一种具有提高材料的强度、稳定性、耐腐蚀性优点的高阻尼形状记忆合金。
本发明的技术方案是：一种高阻尼形状记忆合金，所述的高阻尼形状记忆合金包括最上层的高阻尼层、中间层的镍钛合金和最下层的铜锌铝形状记忆合金组合而成，所述高阻尼层为高阻尼橡胶，所述的高阻尼层占高阻尼形状记忆合金总体分量的12%-17%，所述的镍钛合金占高阻尼形状记忆合金总体分量的39%-41%，所述的铜锌铝形状记忆合金占高阻尼形状记忆合金总体分量的45%-60%。
在本发明一个较佳实施例中，所述的镍钛合金包括镍合金和钛合金。
在本发明一个较佳实施例中，所述的高阻尼层占高阻尼形状记忆合金总体分量的16%，所述的镍钛合金占高阻尼形状记忆合金总体分量的39%，所述的铜锌铝形状记忆合金占高阻尼形状记忆合金总体分量的45%。
本发明的一种高阻尼形状记忆合金，具有提高材料的强度、稳定性、耐腐蚀性的优点。
具体实施方式
下面对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。
其中，所述的高阻尼形状记忆合金包括最上层的高阻尼层、中间层的镍钛合金和最下层的铜锌铝形状记忆合金组合而成，所述高阻尼层为高阻尼橡胶，所述的高阻尼层占高阻尼形状记忆合金总体分量的12%-17%，所述的镍钛合金占高阻尼形状记忆合金总体分量的39%-41%，所述的铜锌铝形状记忆合金占高阻尼形状记忆合金总体分量的45%-60%。
进一步说明，所述的镍钛合金包括镍合金和钛合金，所述的高阻尼层占高阻尼形状记忆合金总体分量的16%，所述的镍钛合金占高阻尼形状记忆合金总体分量的39%，所述的铜锌铝形状记忆合金占高阻尼形状记忆合金总体分量的45%。
进一步说明，高阻尼橡胶具有1.竖向承载力、水平恢复力、阻尼（吸能）三位一体；2.支座滞回特点（载荷-变形曲线）饱满、耗能显著；3.橡胶配方改进、等效阻尼比可达12%以上；4.维修管理成本低（无需其他阻尼装置）；5.大震后残余变形极小，无需更换；6.高阻尼支座[1]表面覆盖有橡胶保护层，保护内部橡胶不受臭氧、紫外线影响，具有更好的耐老化性，50年等效阻尼比降低不到2%；7.HDR高阻尼橡胶的温度依存性较低，广泛用于不同气候地区；8.HDR高阻尼橡胶与天然橡胶一样拥有比较优越的蠕变性能；9.环保无污染。
再进一步说明，镍钛合金是一种形状记忆合金，形状记忆合金是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。它的伸缩率在20%以上，疲劳寿命达1*10的7次方，阻尼特性比普通的弹簧高10倍，其耐腐蚀性优于目前最好的医用不锈钢，因此可以满足各类工程和医学的应用需求，是一种非常优秀的功能材料。镍钛合金除具有独特的形状记忆功能外，还具有耐磨损、抗腐蚀、高阻尼和超弹性等优异特点。镍钛合金是由于受到温度和机械压力的改变而存在两种不同的晶体结构相，即奥氏体相和马氏体相。镍钛合金冷却时的相变顺序为母相（奥氏体相）-R相-马氏体相。R相是菱方形，奥氏体是温度较高的时候，或者去处载荷时的状态，立方体，坚硬。形状比较稳定。而马氏体相是温度相对较低或者加载时的状态，六边形，具有延展性，反复性，不太稳定，较易变形。本发明提供一种高阻尼形状记忆合金，具有提高材料的强度、稳定性、耐腐蚀性的优点。
本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本领域的技术人员在本发明所揭露的技术范围内，可不经过创造性劳动想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书所限定的保护范围为准。
