Description

制造制件内部通道的方法 及具有内部通道的制件
                      发明领域
本发明涉及具有内部小通道的制件，该内部通道在制件内部延伸，并涉及制造此种通道的方法。更准确地说，本发明涉及具有小通道的透平机零件，并涉及制造此种通道的相应方法。
                      发明背景
近代技术进步能通过在基体上凝结汽化物而对基体进行覆盖。使用汽相沉积法，覆盖层可增强即增大基体的化学、物理或电磁特性。根据所寻求的特性不同，覆盖层既可以用与基体相同的材料制成，也可以用不同的材料例如一种抗腐蚀合金制成。
形成一种汽化物的一般方法，是使用电子枪在一种蒸发材料上聚焦一电子束，这种蒸发材料通常是金属。电子束在表面引起高度集中的温度，使金属蒸发物的一部分汽化。金属汽化物占据整个沉积室，该沉积室具有高浓度的金属汽化物，因为在汽化开始前沉积室被抽空气体。汽化物在沉积室内沉积在制件上。沉积的金属冷却，直至在制件上形成固态覆盖层。覆盖层的厚度是通过改变操作条件诸如汽化物的压力、温度、沉积时间和基体的机械操作来控制的。使用电子束的汽相沉积法目前被广泛应用。许多制件例如透平机零件可用汽相沉积法覆盖。
燃汽透平机的透平部分和燃烧部分均经受高温。进入透平的燃汽温度经常超过制造燃汽透平机零件的合金的最大额定工作性能。透平机的零件包括，例如，透平叶片、风扇和壁。
由于透平机零件经受高温，典型的方式是对它们冷却，以保持其结构的完整性。把空气从透平压缩机的出气口转引来冷却叶片、风扇和壁。然而，用压缩机空气冷却降低了透平机的效率，因为不能获得这种空气以支持燃烧。于是，希望使用最小量的压缩空气去冷却透平机的零件。
通常，冷却是使一恒定流量的空气从零件内的内部通道流过而完成的。为了实现恒定流量的空气流经一叶片翼面，叶片翼面内的静压力必须超过叶片翼面外的压力。如果外压力超过内压力，燃烧气体流入叶片翼面内，流入的燃烧气干扰冷却空气流，并可能因过热而损坏叶片翼面。
此外，冷却空气流经弯弯曲曲的通道或小薄膜孔(film hole)时，会产生压力损失，这些通道或孔对于绝大多数气冷翼面而言却是普普通通的。因此，流体压力损失必须最小，以保持内部压力高于外部压力。
对于翼面和其它透平机零件存在一种需求，要求具有能保证空气压力损失低的内冷却通道。
制造叶片翼面的传统方法，采用铸造和多种加工两方面的步骤。铸造步骤需要铸模和型芯。型芯在铸模内用型芯支承元件支承。熔融金属浇注入铸模，环绕型芯和型芯支承元件。金属冷却后，型芯和型芯支承元件被施加的化学溶液溶解。溶解型芯支承元件便在叶片翼面铸件内形成孔。然后，将铸造叶片翼面加工至最终形状。叶片翼面内的冷却通道，由型芯溶解后所留下的空穴所形成。因此型芯的几何形状确定了通道的形状和尺寸。
传统制造翼面通道的方法存在许多缺点，包括高昂的加工成本。此外，由于冷却通道错综复杂的形状，型芯的制造特别复杂。
此外，由于铸造过程固有的限制，通道必须大于最优值，并在厚翼面壁之下设置得更深。例如大型工业燃汽透平高温合金钢叶片，通常具有的壁厚为最大0.189英寸，最小0.070英寸。这些尺寸是西屋501G机(Westinghouse frame 501G)一和二列透平叶片所用的典型尺寸。不幸的是，大而深的通道与使冷却通道更紧靠叶片翼面外表面相比较，从翼面传热的效率更低，这是现有技术众所周知的。设置得大而深的通道的低热传递效率，需要更多的冷却空气，这就降低整个透平机的效率。试图用传统的方法制造更小的通道和更薄的翼面壁是价格昂贵的，并可能带来过低的生产率。
对于像叶片翼面和其它透平机零件等具有大量非常靠近翼面表面的小冷却通道的零件，存在着寻求可靠制造方法的需求，而这种制造方法却没有传统方法那样的低生产率。也存在对于具有这种通道的叶片翼面和其它透平机零件的需求。
                     发明概述
本发明提供在透平机零件上制造小通道的可靠方法。本方法包括：提供具有槽的基体；用填充材料填充槽；将蒸发物沉积在基体和填充材料的表面；去除填充材料。虽然本方法用于制造叶片翼面和其它透平机零件，但也可用于制造需要通道的制件。
在本发明的推荐实践中，提供了具有大量紧靠透平机零件表面的小通道的透平机零件。这些通道使冷却介质能够流过以便冷却零件。

图2为传统蒸发处理设备的原理图。
图3A为具有根据本发明所制造通道的透平机零件正视图。

               对推荐实施例的详细说明
为简化起见，本发明将在透平机叶片的范围内来说明。然而，本发明可应用于任何透平机零件。这里和所附权利要求中所用“透平机零件”这一术语，包括透平叶片、透平风扇、透平转换导管、以及其它需要冷却的零件。
现在参看附图，附图中相同的字符在各图中表示相应的相同装置，图1A至图1E为一透平叶片铸件的根据本发明的制造方法的各步骤的局部视图。图3和4示出了具有上述通道的整个透平零件。参看图1A，透平叶片的基体12a具有基体表面16a，如图所示。虽然表面16a在图1A至1E中均表示为平面，根据本发明的方法同样实用于曲面，如图3C所示。
参看图1B，数个槽11在基体表面16a上制成。槽既可以在透平叶片的基体16a上加工出，也可在铸造透平叶片时将槽11铸成。
因为槽，也就是最终的通道，可容易地用这些方法制成，流体通道的压力损失可以减至最小，这可以通过正确地确定通道总截面面积的大小和使通道制成平滑的壁而没有剧烈的弯曲来实现。于是，槽11的尺寸和数量可取决于特定应用的设计特征。例如，在本发明的实践中，一工业燃汽透平叶片上的槽11可小至大约0.080英寸宽和0.080英寸深。另一个说明本发明实践的例子是，每一槽11的中心线13的距离可设置成小至0.160英寸。
参看图1C，槽11中充填填料14，该填料可用诸如陶瓷材料或金属盐材料。不过，最好用陶瓷材料充填槽。槽11充填后，将填料表面18和基体表面16a抛光，抛光同时暴露了基体表面16a，并使填料表面18本质上具有与基体表面相一致的类似倾斜度和形状。于是，抛光准备了用于蒸发物17沉积的透平叶片表面。
传统的汽相处理设备如图2所示。蒸发物17是在沉积室19内由电子束24生成。由传统的电子枪26激发的电子束24撞击在蒸发材料22的表面，如图1D所示。蒸发物17沉积在放置在沉积室19内的填料表面18和透平叶片基体表面。最好，透平叶片是用机器人控制以便形成均匀的皮层20a、20b、20c、20d的厚度。适当的汽相处理可由：Chromalloy Gas Turbine Corp.的子公司Chromalloy TurbineTechnologies实施，该子公司的地址为：105 Tower Drive，Middletown，NY 10940；和由Interturbine实施，其地址为：1170-111th Street，Grand Prairie，TX 75050.
皮层20a、20b、20c、20d相对于其它翼面尺寸可能薄。例如，皮层20a、20b、20c、20d的厚度，与数英寸的长翼面弦长比较起来，可能大约为0.025英寸至0.030英寸，如图3C所示。皮层20a、20b、20c、20d最好用与基体12a、12b、12c、12d相同的合金钢制成。不过本发明提供不同于基体12a、12b、12c、12d材料制成的皮层20a、20b、20c、20d。
皮层20a在基体表面16a和填料表面18上制成后，将填料14从槽中除去。在推荐的方法中，除去填料14是通过将其暴露在一种腐蚀性溶液中实现的。用腐蚀溶液除去填充材料14的方法，在熔模铸造法技术中是众所周知的。这些方法包括使用一种低温或高温氢氧化钾盐浴槽，或者蒸压釜。当填料14从槽11中去除后，皮层20a和基体12a保留下来以形成通道10a，如图1E所示。
在推荐实施例中，皮层20a、20b、20c、20d的厚度是设计成能经受压力冷却介质流经通道10a、10b、10c、10d所产生的应力，和皮层20a、20b、20c、20d与基体12a、12b、12c、12d膨胀差所固有的应力。
现在参看图3A，一作为例子的透平叶片装配体30如图所示，该透平叶片具有翼面部32、平台34和根36。叶片装配体30通过根36装配在透平转子轮缘35的相应槽中。翼面32包括进气边40、出气边42、凹面44和凸面46。根据本发明，数个翼面通道10b设置在一翼面皮层20b下面。如图3C所示，翼面通道10b可能沿翼面32周边等距设置。
参看图3B，翼面通道10b是设置在叶片铸件基体12b内。翼面通道10b与根通道38压力连通，或与翼面芯48压力连通，或两者的组合，于是使冷却介质39能流经通道10b。最好，透平叶片所用冷却介质39包括压缩空气，尽管蒸汽也可能使用。冷却介质39从设置在翼面32远端的孔排出翼面32。(图中未示出)。
参看图4，作为例子的，具有根据本发明所制成通道的透平风扇装配体50如图所示。透平风扇50具有一翼面部52和两屏蔽板54a、54b。翼面通道10c设置在风扇基体12c之风扇皮层20c下面。此外由本发明方法制成的屏蔽板通道10d设置在每一屏蔽板54a、54b的屏蔽板基体12d内。屏蔽板通道10d通过贯穿翼面的孔(图中未示出)与翼面通道10c连通。最好，风扇通道10c和屏蔽板通道10d形成一封闭回路，蒸汽从中流过以便冷却。作为替换，压缩空气可用以流经此封闭回路以便冷却。
虽然图3和4示出的是一种单方向通道，本发明包括由本方法所制成的径向、切向和倾斜方向的任何组合的通道。此外，应当理解，尽管本发明的众多特征与优点，连同本发明的结构的细节和功能，在上述说明中已经陈述，但是，所公开的仅仅是作为说明，在本发明原则范围内，在所附权利要求广泛意义所表明的整个范围内，其细节可以更改，特别是可以修改形状、尺寸、零件设置、通道和方法。
