Description

连结预形件的添加制造
技术领域
本文中所述的本发明大体上涉及连结。更具体而言,本发明涉及使用添加制造打印软钎焊和硬钎焊预形件的方法。
背景技术
大型发电机中的定子绕组可为水冷的。电枢绕组包括通过铜或不锈钢配件和水冷连接来连接在各端处以形成连续的液压绕组电路的半线圈或定子线棒(通常称为"定子线棒"或"线棒")的布置。水冷电枢绕组线棒包括布置成形成线棒的多个小的矩形实心和中空铜股线。矩形铜股线大体上布置成矩形线束。中空股线均具有用于通过线棒引导冷却剂的内部导管。股线的端部均硬钎焊于相应的液压集管夹。液压集管夹用作用于电枢绕组线棒的电流连接和冷却流连接两者。
液压集管夹为中空连接器,其包括用于冷却液体(典型地,去离子水)进入或流出的包围室。在一个开口端处,夹包围电枢绕组线棒的铜股线的端部。硬钎焊合金将股线的端部区段联结于彼此和液压集管夹。在相邻股线端部之间和在股线端部和夹之间的硬钎焊接头应当保持用于绕组的预期寿命的液压和电气完整性。绕组的典型寿命为大约几十年。
夹与股线的端部之间的硬钎焊接头的内表面恒定地暴露于流过夹和中空股线的去离子氧化水。此外,许多其它液体填充的导管并入暴露于水的硬钎焊接头,如,相位引线、串联回路、连接环、套管,以及需要连接这些导管的许多配件。硬钎焊表面暴露于冷却剂/水可导致导管的腐蚀。某些条件促进硬钎焊接头中的缝隙腐蚀,如:磷、腐蚀性焊剂残余物、铜、适合的腐蚀引发部位和水。
如果硬钎焊接头表面包含接头的表面处或附近的表面缝隙、小孔或孔隙,以及支持腐蚀的临界水化学条件,则腐蚀过程可开始。尤其是在临界缝隙几何形状和水化学条件存在时,腐蚀过程可通过硬钎焊接头发展。硬钎焊接头内的孔隙可加速腐蚀。如果允许通过接头发展,则腐蚀将最终导致通过整个有效硬钎焊接头长度的漏水,并且损害液体填充的导管的液压完整性。因此,存在对防腐蚀的硬钎焊接头的需要。防腐蚀硬钎焊接头的益处预期包括改进的发电机可用性和发电机可靠性。
相比于减去制造方法,添加制造过程例如可大体上涉及一种或更多种材料的累积,以制作净或近净形物体。尽管"添加制造"为工业标准用语(ASTM F2792),但添加制造包含多种名称下已知的各种制造和原型设计技术,包括自由形态制作、3D打印、快速原型设计/工具加工等。添加制造技术能够由多种材料制作复杂的构件。大体上,独立的物体可由计算机辅助设计(CAD)模型制作。一个示例性添加制造过程使用能量束,例如,电子束或电磁辐射,如,激光束,以熔合(例如,烧蚀或熔化)粉末材料,产生固体三维物体,其中粉末材料的颗粒联结在一起。可使用不同材料系统,例如,工程塑料、热塑性弹性体、金属以及陶瓷。激光烧结或熔化为用于功能原型和工具的快速制作的一种示例性添加制造过程。
激光烧结可表示通过使用激光束来烧结或熔化细粉末而产生三维(3D)物体。具体而言,烧结可伴有在低于粉末材料的熔点的温度下使粉末颗粒结块,而熔化可伴有完全熔化粉末颗粒以形成固体均一质量。与激光烧结或激光熔化相关联的物理过程包括至粉末材料的热传递,以及接着烧结或熔化粉末材料。尽管激光烧结和熔化过程可应用于宽范围的粉末材料,但生产路线的科学和技术方面(例如,烧结或熔化速率,以及在层制造过程期间加工参数对微观结构演变的影响)可导致多种生产考虑。例如,该制作方法可伴随多种热、质量和动量传递模式和化学反应。
激光烧结/熔化技术具体可伴有将激光束投射到基底(例如,建造板)上的受控量的粉末材料(例如,粉末金属材料)上,以便在其上形成熔合颗粒或熔融材料的层。通过使激光束沿预定路径(通常称为扫描图案)关于基底移动,层可以以二维限定在基底(例如,"x"和"y"方向)上,层的高度或厚度(例如,"z"方向)部分地由激光束和粉末材料参数确定。扫描图案可包括平行扫描线(也称为扫描向量或阴影线),并且两条相邻的扫描线之间的距离可称为阴影间距,其可小于激光束或熔池的直径,以便实现足够的重叠来确保粉末材料的完全烧结或熔化。使激光沿扫描图案的所有或部分的移动重复可便于沉积并且接着烧结或熔化另外的材料层,由此制作三维物体。
例如,激光烧结和熔化技术可包括使用连续波(CW)激光器,如,在1064nm下或大约1064nm下操作的Nd:YAG激光器。此类实施例可便于特别适合于修复应用或其中随后的机加工操作可接受的相对高的材料沉积速率,以便实现完成的物体。其它激光器烧结和熔化技术可作为备选或此外使用(如例如,脉冲激光器、不同类型的激光器、不同功率/波长参数、不同粉末材料或各种扫描图案),以便于一个或更多个三维物体的产生。

具体实施方式
将在下面描述本发明的一个或更多个特定方面。为了提供这些方面的简明描述,可不在说明书中描述实际实施的所有特征。应当认识到,在任何这种实际实施的开发中,如在任何工程项目中,必须作出许多特定实施决定以实现开发者的特定目的,诸如符合机器相关、系统相关且商业相关的约束,这可从一个实施变化到另一个实施。此外,应当认识到,这种开发努力可为复杂且耗时的,但是对于受益于本公开的技术人员而言,仍将是计划、制作和制造的日常工作。
当介绍本发明的各种方面的元件时,冠词“一”、“一个”和“该”意图表示存在元件中的一个或更多个。用语“包括”、“包含”和“具有”意图是包含的,并且表示可存在除了列出的元件之外的附加元件。操作参数、材料和/或环境条件的任何实例并未排除公开实施例的其它参数/材料/条件。此外,应当理解的是,提到本发明的"一个实施例"、"一个方面"或"实施例"或"方面"不意图解释为排除也并入所叙述特征的附加实施例或方面的存在。
现在参照图1,示出了用于制造如本文中公开的用于涡轮、涡轮机或电动机器构件的连结预形件的添加制造方法100。用语"连结"包括但不限于硬钎焊或软钎焊。硬钎焊是连结过程的组,其通过将材料加热至硬钎焊温度和通过使用具有高于840℉(450℃)且低于基础金属的固相线的液相线的填料金属(焊剂)来产生材料的联合。软钎焊具有与硬钎焊相同的定义,除了如下事实:使用的填料金属具有低于840℉(450℃)且低于基础金属的固相线的液相线。本文中所述的本发明可应用于连结、硬钎焊和软钎焊。
添加制造方法100大体上包括通过打印自熔性硬钎焊(或连结)合金层和非磷硬钎焊(或连结)合金层来形成硬钎焊(或连结)预形件而将多层添加材料累接地熔合在一起。在一些实施例中,硬钎焊/连结预形件可直接地建造/打印在涡轮、涡轮机或电动机器构件上。
作为一个实例,添加制造方法100包括打印自熔性硬钎焊/连结合金的第一打印步骤110。自熔性硬钎焊/连结合金包含磷,并且磷作用为焊剂。磷在硬钎焊期间通过在硬钎焊/连结合金最初熔化和流动时阻止氧干扰来帮助。然而,当磷捕集在固化的接头中时,其可有问题,因为磷提高了接头对水腐蚀的易受性。鉴于此,可使用的磷越少,腐蚀随磷量减少而减少的机会就越高。如本文中使用的,"打印"、"将多层添加材料累接地熔合在一起"或"添加制造"是指导致三维物体的任何过程,并且包括一次一层地按顺序形成物体的形状的步骤。第二打印步骤120将非磷硬钎焊/连结合金打印在自熔性硬钎焊/连结合金上。步骤110和120可重复(步骤130),直到非磷硬钎焊/连结合金大致由自熔性硬钎焊/连结合金封装,或直到获得期望的硬钎焊/连结预形件。例如,如果硬钎焊/连结预形件需要另一层,则添加制造方法100重复步骤110和/或步骤120。如果硬钎焊/连结预形件不需要另一层,则添加制造方法100可结束,或可选地前进至连结过程。打印步骤110和120两者由添加制造过程执行。
添加制造过程包括但不限于粉末床添加制造和粉末床添加制造过程,如通过使用激光或电子束用于将粉末材料累接地熔合在一起。例如,添加制造过程可包括三维打印、激光工程净成形(LENS)、直接金属激光烧结(DMLS)、直接金属激光熔化(DMLM)、选择性激光烧结(SLS)、等离子传递弧、无模成形制造(FFF)等。一种示例性类型的添加制造过程使用激光束来熔合(例如,烧结或熔化)粉末材料(例如,使用粉末床过程)。添加制造过程可使用粉末材料或线作为原材料。此外,添加制造过程可大体上涉及制造物体(制品、构件、部分、产品等)的快速方式,其中多个薄单元层按顺序形成来产生物体。例如,粉末材料层可提供(例如,铺设)并且利用能量束(例如,激光束)照射,以使各层内的粉末材料的颗粒按顺序熔合(例如,烧结或熔化)以使层凝固。
熔合在一起的添加材料可包括多种不同的潜在材料,例如,其可取决于添加制造方法的类型和/或用于硬钎焊预形件的特定应用。例如,添加材料可包括可由激光束或其它能量源熔合(例如,烧结)的任何材料。在一些实施例中,添加材料可包括粉末金属。通过非限制性实例,此类粉末金属可包括钴铬合金、铜合金、镍合金、锡合金、银合金、铝及其合金、钛及其合金、镍及其合金、不锈钢、钽、铌或它们的组合。
图2示出了根据本发明的方面的由添加制造过程制作的硬钎焊/连结预形件200。硬钎焊预形件200呈圆柱或垫圈的形式,并且包括外自熔性硬钎焊/连结合金层210和内非磷硬钎焊/连结合金层220。内非磷硬钎焊合金层220可由自熔性硬钎焊合金层210大致或完全封装。仅作为实例,自熔性硬钎焊合金210可包括BCuP合金、CuP合金、CuSnP合金、CuSnNiP合金、CuAgP合金、磷、硼、氟、氯、钾,或任何其它适合的自熔性硬钎焊/连结材料或合金。作为又一个实例,非磷硬钎焊合金220可为BAg合金,如,BAg-8、BAg-18或BAg-24、BNi合金、BAu合金,或任何其它适合的非磷硬钎焊/连结合金。BAg-18合金包括银(Ag)、铜(Cu)和锡(Sn),并且具有大约1115℉的熔点,具有大约1325℉的液相线温度,并且典型地在高于1325°F的温度下硬钎焊。Bag-24合金也可用作非磷硬钎焊合金,并且包括银(Ag)、铜(Cu)、锌(Zn)和镍(Ni),并且具有大约1220℉的熔点和大约1305℉的液相线温度。
图3示出了沿图2的截面线3-3的硬钎焊/连结预形件200的截面视图。非磷硬钎焊合金220位于硬钎焊预形件200的中心中。自熔性硬钎焊合金210包绕并且可大致封装非磷硬钎焊合金220。图4示出了沿图3的截面线4-4的硬钎焊预形件200的截面视图。可看到的是,非磷硬钎焊合金220由自熔性硬钎焊合金210包绕,并且这使含磷自熔性硬钎焊合金210对硬钎焊预形件200的所有外表面而言暴露。
图5示出了类似于图4的视图的硬钎焊/连结预形件500的截面视图。硬钎焊500具有中心部分,其包括类似于图1-4中所示的非磷硬钎焊合金220。然而,自熔性硬钎焊合金以多个层510, 512, 514, 516打印。层510, 512, 514, 516中的各个可具有不同百分比的磷或其它构成元素,并且各层还可具有不同的熔点。仅作为一个实例,自熔性硬钎焊合金层510(最外层)可包括BCuP-5,其为15%的银(Ag)、80%的铜(Cu)和5%的磷(P)。下一层512可为BCuP层,其具有仅3%的磷,后接为仅具有2%的磷的BCuP层的层514,并且最后层516为仅具有1%的磷的BCuP层。在该实例中,外层具有高于内层的磷百分比。层510, 512, 514, 516在它们朝非磷硬钎焊合金220向内发展时,可逐渐地或急剧地增大或减小磷的百分比。该构造仅将磷放在需要其的地方,在将与氧接触的外部分上。整个硬钎焊预形件500具有减少的磷水平,并且未来接头腐蚀的潜在性极大降低。作为另一个实例,层510可为包含磷的唯一层。作为备选,外层可具有低于内层的磷百分比。磷的百分比变化还可横跨各种层线性地或指数地变化。
自熔性硬钎焊合金层510, 512, 514, 516还可具有不同的熔点。例如,层510可具有大约1190℉的熔点和大约1300℉的液相线温度,层512可具有大约1180℉的熔点和大约1290℉的液相线温度,层514可具有大约1170℉的熔点和大约1280℉的液相线温度,并且层516可具有大约1160℉的熔点和大约1270℉的液相线温度。在该实例中,外层(510, 512)具有高于内层(514, 516)的熔点的熔点。如特定应用中期望的,层510, 512, 514, 516可构造成具有升高或降低的熔点,并且可使用多于或少于四层。
图6示出了根据本发明的方面的打印在待硬钎焊/连结的部分600上的硬钎焊预形件200的透视图。部分600可为管或配件,并且硬钎焊预形件200逐层打印在部分600上。部分600可为需要硬钎焊的涡轮机或电动机器的任何部分或构件。如图6中所示,图7为沿截面线7-7的截面视图。硬钎焊预形件200具有与部分600接触的内自熔性硬钎焊合金层210、中间非磷硬钎焊合金层220,以及外自熔性硬钎焊合金层210。
在施加足够的热时,三个硬钎焊合金层210,220和210所有都熔化。与铜部分接触的载磷层210在硬钎焊期间自熔,并且将良好粘合给予至部分。之间的无磷层220稀释富磷层210,以最小化接头中的Cu3P相的残余存在,该Cu3P相是可用作用于腐蚀冲击的部位的冶金相。所得的硬钎焊接头在与流动流体(例如,冷却水或任何冷却介质)的接触点处提供加强的腐蚀保护。
图8为呈薄板形式的硬钎焊/连结预形件800的透视图。外层为自熔性硬钎焊合金210。内层(未示出)可由非磷硬钎焊合金220形成。图9为呈盘形式的硬钎焊/连结预形件900的透视图。外层为自熔性硬钎焊合金210。内层(未示出)可由非磷硬钎焊合金220形成。
该书面的描述使用实例以公开本发明(包括最佳模式),并且还使本领域技术人员能够实践本发明(包括制造和使用任何装置或系统并且执行任何并入的方法)。本发明的可专利范围由权利要求限定,并且可包括本领域技术人员想到的其它实例。如果这些其它实例具有不与权利要求的字面语言不同的结构元件,或者如果这些其它实例包括与权利要求的字面语言无显著差别的等同结构元件,则这些其它实例意图在权利要求的范围内。
