Problems solved by technology

[0005] However, the above preparation methods still adopt the principle of chemical coating, and a large amount of chemical plating solution is used in the process, which still produces a large amount of waste liquid, which does not meet the current environmental protection requirements, and still cannot fundamentally eliminate the Ni-P film. Defects occur, and the corrosion resistance needs to be improved

Abstract

The invention discloses an ion plating Ni-P nanometer laminated membrane. The nanometer laminated Ni-P membrane of a laminated structure is acquired in a sedimentation manner through an ion plating technology with ferrous metal as a substrate material, the total thickness of the nanometer laminated Ni-P membrane is adjustable within the range of 2 microns-80 microns, and the self-corrosion potential of the nanometer laminated Ni-P membrane is 230 mV or above. The microstructure of the nanometer laminated Ni-P membrane is more compact, and the abrasion resisting performance and the corrosion resisting performance of the plating membrane are remarkably improved. The invention further discloses a preparation method of the ion plating Ni-P nanometer laminated membrane. By adopting the ion plating technology for sedimentation, it does not need to use any chemical plating solution, no waste liquid is generated, and environmental friendliness is achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of Ni-P alloy plating, in particular to an ion-plated Ni-P laminated film and a preparation method thereof. 【Background technique】 [0002] Ni-P alloy coating is often used to improve the service life and reliability of parts due to its excellent wear resistance, corrosion resistance and high hardness. It is used in the chemical industry, electronics industry, precision machinery, aerospace industry, automobile industry , mining machinery and agricultural machinery are widely used. [0003] The methods for obtaining Ni-P alloy coatings in the prior art mainly include electrodeposition and electroless plating. Among them, the electrodeposition method uses the base material as the cathode, the plated metal or the insoluble material as the anode, applies a voltage between the cathode and the anode, and obtains a coating on the surface of the base material through the action of an electric current. It has fas...
