摘要： A method of removing recast from a substrate is disclosed. The method includes chemically removing the recast using an etchant, which provides a visual indication of the presence of the recast when the part has been removed from the etchant. One example chemical etchant is comprised of a sulfuric acid solution that includes sodium chloride, sodium fluoride and ammonium persulfate. After chemical removal of the recast from the substrate, the recast is physically removed from the substrate, for example, by media blasting. The chemical and physical recast removal process can be repeated as desired. To ensure that all the recast has been removed, the substrate is wiped, for example, using a cloth. If all the recast has been removed, the cloth will not change in appearance or color.

摘要： The present invention relates to a zinc-diffused nickel alloy coating for corrosion and heat protection and to a method for forming such a coating. The coating method broadly comprises the steps of forming a plain nickel or nickel alloy coating layer on a substrate, applying a layer of zinc over the nickel or nickel alloy coating layer, and thermally diffusing the zinc into the nickel alloy coating layer. The coating method may further comprise immersing the coated substrate in a phosphated trivalent chromium conversion solution either before or after the diffusing step. The substrate may be a component used in a gas turbine engine, which component is formed from a steel material.

摘要： The invention provides method and apparatus for chemical milling of a metal part in a milling solution that reduces hydrogen absorption by the part wherein, the metal part to be milled, which serves as the anode, and a cathode of more noble metal than the anode, are mounted in such solution. Unlike the prior art, the cathode and anode are separated in such solution but electrically connected by a conductor therebetween, which conductor is insulated from the milling solution. Thus anode and cathode are mounted, spaced apart in the milling solution, so that metal dissolves from the anode surface, milling such part while electrons flow from anode to cathode by said conductor so that hydrogen forms at the cathode, removed from the anode part, to reduce hydrogen absorption by such part.The anode part can be of, eg. titanium and the cathode of a more noble metal, eg. platinum, which serves to draw the hydrogen to the cathode and away from the anode part, preventing or reducing absorption of hydrogen into, eg. the titanium part and consequent hydrogen embrittlement thereof, which occurs in the prior art.
摘要翻译： 本发明提供了一种用于化学研磨研磨溶液中的金属部件的方法和装置，其减少了其中作为阳极的待研磨的金属部件和比阳极更贵的金属的阴极的部件的氢吸收， 安装在这样的解决方案中。 与现有技术不同，阴极和阳极在这种溶液中分离，但是通过其间的导体电连接，该导体与研磨溶液绝缘。 因此，阳极和阴极在铣削溶液中间隔开，使得金属从阳极表面溶解，研磨这样的部分，同时电子由所述导体从阳极流到阴极，使得在阴极处形成氢，从阳极部分去除， 以减少这种部件的氢吸收。 阳极部分可以是例如。 钛和贵金属的阴极，例如。 铂，其用于将氢吸入阴极并远离阳极部分，防止或减少氢的吸收，例如， 在现有技术中发生的钛部分和随之而来的氢脆化。

摘要： Electroless plating compositions are described which produce a boron containing nickel coating. The compositions comprise a water soluble nickel salt, a chelating agent, an alkali metal hydroxide, a boron containing reducing agent, and thiocarbanilide. The composition is particularly useful for providing such coatings on gas turbine engine parts and results in improved wear resistance.
