摘要： A water-cooled stator bar clip for electrical generators and a method for applying a corrosion-resistant protective coating, preferably Sc, Ti, Cr, Zr, Nb, Mo, Hf, Ta, W, Ni, and Al, and their alloys or oxides to existing stator bar end fittings in order to significantly reduce the possibility of leaks through the brazed connections of the copper stator bar end connections. The coatings can be applied locally using various known physical vapor deposition (“PVD”), chemical vapor deposition (“CVD”) or other direct coating techniques known in the art. For example, the coatings can be applied using ion plasma deposition, sputtering or wire arc techniques (all PVD processes) or by using electroplating, high velocity oxygen free (“HVOF”) deposition, DC arc or electroless plating. Preferably, the coatings are applied either to new stator bar clips or to existing clips in the field.

摘要： A method for metallurgically bonding a stator bar to a coupling to reduce the incidence of leak paths resulting from corrosion. The stator bar comprises strands through which a liquid coolant can flow. Adjacent ends of the strands are received in an interior cavity of the coupling through an opening in the coupling. A joining material is provided on a first portion of the stator bar within the coupling opening and adjacent the ends of the strands. The first portion is heated to melt the joining material. At essentially the same time, a second portion of the stator bar outside the coupling is also heated. Once the joining material is suitably molten, the first portion is allowed to cool while the second portion remains heated, thereby causing the joining material nearest the ends of the strands to solidify first.
摘要翻译：一种用于将定子棒冶金结合到联接器上以减少由腐蚀引起的泄漏路径的发生的方法。定子杆包括液体冷却剂可以流过的线。股线的相邻端部通过联接器中的开口接收在联接器的内部空腔中。接合材料设置在定子棒的第一部分的耦合开口内并且与股线的端部相邻。将第一部分加热以熔化接合材料。在基本上相同的时刻，联轴器外的定子杆的第二部分也被加热。一旦接合材料适当地熔融，则允许第一部分冷却，同时第二部分保持加热，从而使最接近线股末端的接合材料首先固化。

摘要： A liquid-cooled armature bar end fitting-to-strand brazed connection. The end fitting is comprised of a main body and a cover, and defines a cavity, a bottom wall of which is defined in part by the cover. An armature winding bar strand package including solid strands and hollow strands arranged in a tiered array extends into the end fitting so that at least the free ends of the hollow strands extend beyond the bottom wall, into the cavity. The side wall of the cavity is spaced from the hollow strands. A braze alloy joins the strands to each other and to the end fitting. The braze alloy forms an isolation layer over the free ends of the solid strands and over the said bottom wall of the cavity to a depth above a horizontal junction between the main body and the cover.
