| It is a very high temperature when a turbo engine works (over800℃). In order to improve the blade’s Oxidation resistance and hot corrosion, we need to plat a layer of Al-Si-Y on the surface by Vacuum arc deposition. The cathode target as the nuclear part of a vacuum arc deposition, according to the working status, the Material needs itself to be Compact, and without the defect that could affect the Electrical conductivity such as Non metallic inclusion, air hole, Shrinkage hole, Loose, pinhole to Guarantee the performance of continues of the vacuum arc deposition. Therefore, it is extremely important for the quality of the cathode target. First, without any deposition of the cathode target, Casted by no lacks and tested by X-ray. Secondly, make an Aluminum alloy which is empty inside to come through the cooling water. Thirdly, we optimized the procedure of chemical plating Tin and ensure the Composition of the fiber material. For all the above points, we make the cathode target. At last, through the plating experiment, it proves that the material has the same level with the import one by Russia. It will fit the needs to be used as a cathode target. |
