A method for preparing a high-gloss metal surface based on a brush nickel-plating and polishing composite process

Abstract

The invention relates to a high-smoothness metal surface preparation method based on a nickel electro-brush plating and polishing compound technology, and belongs to the technical field of metal surface treatment. The preparation method comprises the steps that a rotatable plating pen with polishing cloth is adopted as an anode, metal to be polished is adopted as a cathode, powering on is carried out, and the metal semi-submerged in nickel electro-brush plating and polishing compound liquid is polished. The preparation method has the beneficial effect that a high-smoothness metal surface can be obtained quickly.

Description

technical field [0001] The invention relates to a high-gloss and clean metal surface preparation method based on an electric brush nickel-plating and polishing composite process, and belongs to the technical field of metal surface treatment. Background technique [0002] Existing metal surface polishing technologies include mechanical polishing, fluid polishing, magnetic abrasive polishing, ultrasonic polishing, chemical polishing and electrolytic polishing. Among them, mechanical polishing, fluid polishing, magnetic abrasive polishing and ultrasonic polishing remove asperities on the metal surface through frictional cutting to reduce the roughness of the metal surface; among the above polishing methods, the mechanical polishing has the highest polishing precision, and the metal surface The roughness Ra is 0.008μm, but its disadvantages are low material removal rate and low polishing efficiency. Chemical polishing and electrolytic polishing react with the metal surface thro...

Problems solved by technology

In some engineering application fields with extremely high requirements on the metal surface, for example, when the thickness of the oil film between the metal sample and the glass plate is measured by optical interferometry, the thickness of the oil film is tens of nanometers to tens of nanometers, and the surface roughness of the metal sample , smoothness, leveling, reflectivity, etc. all have an impact on the measurement results, and the existing polishing process cannot fill the micro-recesses. It is necessary to use mechanical and chemical methods to remove the materials around the micro-recesses to achieve a super-mirror state with a defect-free surface. Not only does it take a lot of time, but it also prevents excessive polishing from exposing metal crystal defects, so the existing polishing process cannot complete the efficient preparation of high-precision, high-gloss metal surfaces
