sufyan Posted October 1, 2018 Share Posted October 1, 2018 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 Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted October 1, 2018 Share Posted October 1, 2018 Need to define how it will be used: once an hour with light loading could be different than 150 times a minute under heavy loading. Quote Link to comment Share on other sites More sharing options...
sufyan Posted October 2, 2018 Author Share Posted October 2, 2018 its for robot, so basically. it is going to used very much for motion, (speed motion sometimes). and most of the time light load Quote Link to comment Share on other sites More sharing options...
stevomiller Posted October 2, 2018 Share Posted October 2, 2018 My understanding is that most of these are heat treated for maximum toughness with hard chrome surface treatment to provide a lubricious and long wearing surface. Sufyan, I hate to push off this answer, but you should be looking to industry trade journals and white papers for this information, as it is a very specific usage that is also affected by the exact alloy used, etc. Quote Link to comment Share on other sites More sharing options...

MotoMike Posted October 2, 2018 Share Posted October 2, 2018 we going to see this robot? Oooh I hope its a Battle Bot!! Quote Link to comment Share on other sites More sharing options...
sufyan Posted October 2, 2018 Author Share Posted October 2, 2018 haahah no .its a robot who has main goals to help humans, especially in situation where humans cannot do the task or endanger them, the robot still under development, i will share it when it done Quote Link to comment Share on other sites More sharing options...
Daswulf Posted October 2, 2018 Share Posted October 2, 2018 Well that "could" be a battle bot then. Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted October 2, 2018 Share Posted October 2, 2018 You may also wish to look into Molybdenum coated rods depending on the abrasion and wear resistance needed Quote Link to comment Share on other sites More sharing options...
sufyan Posted October 2, 2018 Author Share Posted October 2, 2018 yes sir, im now working on coating, method is electrodepostion, coat alloy is base nickel with chromium- molybdenum- cobalt... Quote Link to comment Share on other sites More sharing options...
Jclonts82 Posted November 5, 2018 Share Posted November 5, 2018 DLC, diamond like coating. There is a company in Tucson Arizona that I am VERY familiar with the owners/operators. Duralar. They can coat any conductive metal in a matrix that has a carbon atomic structure that is diamond like. It has incredible wear resistance, as well as a natural dry lubricity. Their coatings put chrome coatings to shame. You can use less expensive base steel that doesn't need as much wear properties, and focus more on strength.
