Hello friends
I want to coat a palladium-nickel alloy with a ratio of 92-8. The machine I have access to has an one electron beam and four crucibles.
I have two solutions.
1- Separate coating of palladium and nickel and then annealing in vacuum.
2- Placing palladium and nickel in a crucible and coating palladium-nickel alloy.
Which do you think is more suitable?
Is there any other solution?
Thanks
Electron beam evaporation is a process in which a material is heated to a high temperature in a vacuum chamber and then evaporated onto a substrate. To coat palladium-nickel alloy using electron beam evaporation, the alloy must first be placed in an electron beam evaporator. The evaporator is then heated to a temperature that is high enough to cause the alloy to evaporate. The evaporated alloy is then deposited onto the substrate, forming a thin film. The thickness of the film can be controlled by adjusting the power of the electron beam and the rate of evaporation. The process is typically used to create thin films for use in electronics, optics, and other applications.
Solution 1:
Separate coating of palladium and nickel and then annealing in vacuum This solution involves coating the palladium and nickel separately in the electron beam evaporation machine. The palladium and nickel should be placed in separate crucibles and then evaporated using the electron beam. Once the coating is complete, the alloy should be annealed in a vacuum chamber to ensure that the two metals are properly bonded together. This solution is suitable for coating a palladium-nickel alloy with a ratio of 92-8.
Solution 2:
Placing palladium and nickel in a crucible and coating palladium-nickel alloy This solution involves placing the palladium and nickel in the same crucible and then evaporating them together using the electron beam. This will result in a coating of the palladium-nickel alloy with a ratio of 92-8. This solution is also suitable for coating a palladium-nickel alloy with a ratio of 92-8.
Solution 3:
Is there any other solution? Yes, there is another solution which involves using a sputtering machine to coat the palladium-nickel alloy. In this method, the palladium and nickel are placed in separate targets and then sputtered onto the substrate. This method is suitable for coating a palladium-nickel alloy with a ratio of 92-8.
Dr. Seyedali Hosseini,
I suggest you to use solution 1 if you to produce your coatings.
I can explain my opinion. In therhmal PVD procces when solid material is evaporating on a substrate the chemical compositon of thin film depends on partial pressure of gases of each component. To get required ratio between Ni and Pd in the film you should do serious research first. It is easier to do deposition Ni and Pd film separately and then anneal obtained composition. I can say that this problem will appear even when magnetron or ion beam sputtering is using.
