Molybdenum Disulfide Coating
Molybdenum disulfide coating processing technology is the best way to solve the occlusion of metal and non-metallic by surface self-lubricating anti-wear. Coated with molybdenum disulfide lubricating anti-wear coating material to form the coating, the product can achieve a qualitative leap in performance, so the products’ performance has great improved.
Molybdenum disulfide has a layered structure and the crystal is hexagonal, so MoS2 is easy to slide, which can play a role in reducing friction. On the other hand, the ionic bond between the Mo atom and the S atom makes the MoS2 lubricating film have high strength, which can prevent the lubricating film from penetrated at the metal surface by protruding part. Besides, the S atom is exposed on the MoS2 crystal surface, resulting in a strong adhesion. MoS2 coating has low friction coefficient and excellent friction performance under vacuum and strong radiation environment, so it has wide application in space machinery.
MoS2 coatings are mainly manufactured by electrophoretic deposition method, water boiling method and brushing method. All of the three preparation methods are mechanically combined to form a coating, in which the bond strength and surface hardness highest of the coating prepared by electrophoretic deposition is the highest.
