Hello,
i am currently doing a little research for my university about the material used to manufacture hydraulic cylinder for robotic application.
and so far i have found that ductile iron for cylinder, and nickel-chromium alloy for the piston rods.
as for surface treatment we might use electrodposition to enhance he wear and corrosion resistance if the piston rods was made from mild carbon steel for example, but there's no heat treatment for rod or cylinders . what do you think about that ?
thanks
