Abstract: A coating method includes vaporizing a portion of a cathode to form a metallic plasma, and directing the metallic plasma toward the workpiece. A first magnetic field generator, disposed in a first electrically conductive portion of a first stinger cup, is operated to steer the electrical arc about at least one evaporative surface of the cathode. a second portion of the electrically conductive stinger cup is selectively contacted with the cathode, and the first portion of the first stinger cup is spaced from the second portion from by a thermally insulating layer therebetween. The thermally insulating layer is disposed directly between the first magnetic field generator and the cathode when the first stinger cup is in contact with the cathode.

Abstract: The present invention provides a Cr-rich cathodic arc coating, an article in turbine blade coated with the chromizing over cathodic arc coating, and a method to produce the coating thereof. The Cr-rich cathodic arc coating in the present invention comprises a cathodic arc coating and a diffusion coating deposited atop the cathodic arc coating to enforce hot corrosion resistance. The hardware coated with the chromizing over cathodic arc coating in the present invention is reinforced with superior-hot corrosion resistance. The present invention further provides a novel method for producing the chromizing over cathodic arc coating by re-sequencing coating deposition order. The method in the present invention is efficient and cost-reducing by eliminating some operations, e.g., DHT and peening, between the cathodic arc coating and the diffusion coating. The hot corrosion resistance in the present invention results from the high Cr content in the surface of the coating.

Abstract translation: 本发明提供了一种富铬阴极电弧涂层，涂覆有镀铬阴极电弧涂层的涡轮叶片中的制品及其制备方法。 本发明的富铬阴极电弧涂层包括阴极电弧涂层和沉积在阴极电弧涂层顶上的扩散涂层以实现耐热腐蚀性。 在本发明中涂覆有阴极电弧涂层的硬度被硬化并具有优异的耐热腐蚀性。 本发明还提供了一种通过重新排序涂层沉积顺序来生产阴极镀层上的镀铬的新方法。 通过消除阴极电弧涂层和扩散涂层之间的一些操作，例如DHT和喷丸处理，本发明的方法是有效的和降低成本的。 本发明的耐热腐蚀性由涂层表面的高Cr含量导致。
