20Cr Geomet Coating carburizing heat treatment bushing for Molding Ejection.
Description
The bushing is a matching part used outside the mechanical parts to achieve the functions of sealing, wear protection, etc. It refers to the ring sleeve that functions as a gasket. In the field of valve applications, the bushing is inside the valve cover, and corrosion-resistant materials such as polytetrafluoroethylene or graphite are generally used for sealing.
Geomet is more environmentally friendly and has stronger salt spray performance.
The appearance of Jiao Mei Te coating is matt silver gray, and its gloss is slightly darker than Dacromet coating. It is an inorganic coating that combines ultra-fine zinc flakes and aluminum flakes in a special binder.
Advantages:
(1) Barrier protection: The treated layered zinc flakes and aluminum flakes provide an excellent barrier between the steel substrate and the corrosive medium, preventing the corrosive medium and depolarizer from reaching the substrate.
(2) Electrochemical effect: The zinc layer is corroded as a sacrificial anode to protect the steel substrate.
(3) Passivation: The metal oxide produced by passivation slows down the corrosion reaction speed of zinc and steel.
(4) Self-repairing effect: When the coating is damaged, zinc oxide and carbonate move to the damaged area of the coating, actively repairing the coating and restoring the protective barrier.
