      we need to prevent the corrosion of a machine in the mountains, the machine polishes the surface of stone. it uses rotating disks and a lot of water. also it is an old machine with some parts having lost up to 1 mm in thickness due to rust.
      we are trying to find a passive corrosion protection technique and so far we have found water treatment (adding corrosion inhibitors to the water used by the machine). i'm simply asking about other passive techniques and especially whether we can use sacrificial anode technique (or similar methods) in open air.

      I would like to try and get a clarification or better understanding of the situation. You are trying to protect the parts of the machine in open air that are rusting and deteriorating only. The parts submerged in water are not of concern at this point? Do any of these surfaces you wish to protect have contact points?

      actually all the parts are in open air, the water flows on the stones to help polish the surface, some of the water is sprayed due to the rotation of the disks and what doesn't spray flows through the machine to the drain. so to answer your question yeah the parts we need to protect are in open air

      so only air protection is required,isn't it?
      you can use coating method on it.
