I am currently debating with someone on a different platform and he brought up the phenomenon "cold welding." I must admit that I had never heard of that before, so I have been reading about it for a while now. I have been trying to find any documentation that NASA employed some kind of mitigation techniques to avoid moving parts being fused together. From what I imagine, the lander had only a few moving parts, but I am curious if anyone knows if they did anything to prevent cold welding. I am also curious about the cameras. The shutter on the 70MM camera is a moving part, and most likely made of aluminum, but I can't find any information about it. It seems as if aluminum is rather prone to cold welding. I am guessing they used a lubricant on the moving parts of the camera, but I don't know if there is a place to find that information.
Any help would be awesome. This denier I am writing back and forth with is bringing up topics I have never looked into before, so I am happy to learn new things as I am doing my research.
