Method for preparing cross section metallographic specimen of stainless steel ultrathin precision strip steel

Abstract

The invention belongs to the technical field of metallographic test devices, and particularly relates to a method for preparing a cross section metallographic specimen of stainless steel ultrathin precision strip steel. The method for preparing the cross section metallographic specimen of the stainless steel ultrathin precision strip steel. The method comprises the following steps: (1) pre-treating the stainless steel ultrathin precision strip steel; (2) pretreating an anode material; (3) preparing an electroforming solution; (4) electroforming; and (5) grinding the specimen. The method has the advantages that the blank of preparing a stainless steel ultra-thin precision strip steel cross section metallographic specimen at present is filled, the problem that the stainless steel ultra-thin precision strip steel cross section metallographic specimen cannot be prepared is solved, the stainless steel ultra-thin precision strip steel cross section metallographic specimen can be efficiently manufactured with high quality, and the metallographic structure of the stainless steel ultra-thin precision strip steel cross section metallographic specimen can be well presented.

Description

technical field [0001] The invention belongs to the technical field of metallographic test devices, in particular to a method for a cross-sectional metallographic sample of stainless steel ultra-thin precision strip steel. Background technique [0002] Stainless steel ultra-thin precision strip steel, also known as "hand-sheared steel", has a thickness of ≤0.05mm. It is an extension of stainless steel cold-rolled products and a high-end product of cold-rolled stainless steel. It has extremely thin thickness, excellent strength, and ultra-high Flatness and exquisite surface are the key basic materials for high-end manufacturing and are irreplaceable. It is widely used in various industries such as aerospace, military nuclear power, high-end electronics, automobiles, home appliances, medical care, and petrochemicals. In recent years, with the rapid development of lightweight and integration of consumer electronics products, stainless steel ultra-thin precision strips have bee...

AI Technical Summary

Problems solved by technology

Since the thickness of stainless steel ultra-thin precision strip steel is less than or equal to 0.05mm, the mounting medium does not form a tight bond with the stainless steel ultra-thin precision strip steel by using conventional methods of mounting samples such as hot mounting and cold mounting, so the cross-sectional gold When grinding the metallographic sample, the edges of the ultra-thin precision stainless steel strip are all curled, and the grinding quality cannot be observed during grinding, resulting in the inability to complete the grinding of the metallographic sample, which directly affects the detailed observation of its structure and hinders Further research and development of stainless steel ultra-thin precision strip steel

[0004] At present, there are no reports at home and abroad on the method of grinding metallographic samples of stainless steel ultra-thin precision strip steel cross-sections, and no related patents have been seen.
