CYLINDER ROD HARD CHROME PLATING AND GRINDING

  Cylinder rod is a very important part for hydraulic cylinder, Wuxi YUTONG as a professional manufacturer of cylinder piston rod, we will have many steps to guarantee the quality of the rod, like  Inspection,grinding & peeling,cleaning & masking, and then hard chrome plating . Hard chrome plating, and then OD grinding is an excellent answer for repairing and/or providing wear resistance to parts such as cylinder shafts , rolls, hydraulic cylinders, rams, pistons and rods.   It is used in everything from plating jewellery with gold to applying reflective metal plating to satellites and spacecraft. In this process, objects to be plated are placed in a bath containing a solution of dissolved metal molecules (in our case this metal is a special Chromium formulation). Electrodes are attached to the object to be plated and a positive current is applied to the solution. As the current runs through the solution and out through the electrodes, it causes the dissol...

WHAT IS HARD CHROME PLATING?

  Hard chrome plating is an electroplating process in which chromium is deposited from a chromic acid solution. Thickness of hard chrome plating ranges from 2 to 250µm. Various types of hard chrome include micro-cracked chromium, micro-porous chromium, porous chromium and crack free chromium. It is essential that the micro-cracked and porous coatings have a minimum thickness between 80-120µm in order to confer adequate corrosion resistance. Micro-cracked chromium has a Vickers hardness of 800-1000 kg/mm 2 , while crack-free chromium has Vickers hardness between 425-700 kg/mm 2 . The formation of micro-porous chromium is achieved by a specialised plating method involving the use of inert suspended particles. Porous chrome plating is developed by etching electrodeposited chromium. These are designed to retain lubricant, for sliding and bearing type applications. Chrome plating is used for wear and corrosion resistance in addition to its tribological (low friction) characteristics. H...

FEATURES & BENEFITS OF HARD CHROME PLATING

  Hard chrome plating   also sometimes called chromium plating, is an electroplating process in which a layer of chromium is deposited onto a surface. This layer of chromium protects and extends the life of the part by improving wear resistance, reducing the coefficient of friction, and increasing mild corrosion resistance. These coatings can be applied in a wide range of thicknesses from as low as 0.0002” to 0.020” or more. Hard chrome is widely used in many applications spanning across every industry such as aerospace and agriculture equipment parts. Some common applications include  hydraulic cylinder rods ,valves, crankshafts,  induction hardened piston rods , bailing hooks, harvester rolls, actuator housings, injection molds, dies,  rod cylinders  and rollers. FEATURES & BENEFITS OF HARD CHROME PLATING Increased hardness of HRC 65-70 Excellent sliding wear resistance Great abrasion resistance Low coefficient of friction Excellent release ...

The Difference Between Hard Chrome Plating And Nickel-Chrome Plating

Hard chrome plating  is likely the least understood of these three chroming processes. Hard chrome plating involves heavy coatings of chromium in order to provide wear resistance, oil retention and lubricity. It is not decorative and is instead used to add durability to such things as piston rings,  hydraulic cylinder rods , thread guides and molds. It derives its name from its measurable thickness and is normally applied to steel substrates. While it is metallic and shiny, it is not a decorative finish. Hard chrome plating is a good option for wheels or bumpers. Nickel chrome plating also called decorative chrome plating, nickel-chrome plating involves electroplating a thin layer of nickel onto the item before the chrome layer is plated onto it. The layer of nickel adds smoothness, reflectivity and corrosion resistance. The chrome layer that is applied on top of it is very thin, measuring in the millionths of an inch. The appearance of decorative chrome primarily comes from t...
