Title:
PARTICULATE MATTER APPLIED TO SOLID ELECTROLYTIC POLISHING OF METAL PART AND APPLICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/124980
Kind Code:
A1
Abstract:
A particulate matter applied to solid electrolytic polishing of a metal part and an application method. The particulate matter is solid particles of a porous structure; the particulate matter contains hydroxyl groups, and the interiors and/or surfaces of pores of the particulate matter contain an electrolyte. Compared with physical polishing and chemical polishing, the particulate matter for solid electrolytic polishing of a metal part can fully polish the portion of the metal part that is inconvenient to grind, and does not need a large number of chemical oxidation agents and electrolytes in the polishing process, and is therefore environmentally friendly and high in safety. In addition, the particulate matter can be regenerated after being used for a period of time, thereby greatly improving the service life, and reducing the cost.
