    Comparison Of Features Of Single Hydraulic Prop Accessories

    Comparison performance of electroplating and blackening of hydraulic acrow props accessories:

    Zinc-nickel alloy has stronger anti-rust ability and better corrosion resistance than blackening. The zinc-nickel coating has both mechanical protection and electrochemical protection for the iron matrix, and has good corrosion resistance. The zinc-nickel alloy-coated piston body can extend the service life of the single hydraulic prop better than the blackened piston body, prevent rust, and reduce the probability of leakage of the hydraulic acrow props.

    Features of electroplating treatment of hydraulic prop accessories:

    Electroplating is an electro-ion deposition process, which uses electrodes to pass current to make the metal adhere to the surface of the object. Its purpose is to change the characteristics or size of the surface of the object. Electroplating is an electrochemical reaction.

    The surface blackening treatment of steel parts, which is also called bluing, is a chemical reaction. The principle is to rapidly oxidize the surface of steel products to form a dense oxide film protective layer. The purpose of blackening treatment is to prevent corrosion and rust. In addition to its protective hydraulic prop effect, it is often used as a transition to paint decoration on the outside to improve the adhesion of the coating.
