Application method of novel 8-series aluminum alloy (Al-Li) etchant solution

Abstract

The invention discloses an application method of a novel 8-series aluminum alloy (Al-Li) etchant solution. The application method is characterized by comprising the steps that 1, a 8-series aluminum alloy (Al-Li) sample is grinded and polished; 2, the 8-series aluminum alloy (Al-Li) sample is blown and dried through hot air blown by an electric hair drier, and the surface of the sample is clean and warm so that the etchant solution and the sample can react smoothly; 3, the etchant solution is dropwise sprayed on the surface of the 8-series aluminum alloy (Al-Li) sample and wiped with a cotton ball continuously so that the surface of 8-series aluminum alloy (Al-Li) can be evenly coated with the etchant solution, and the corrosion time ranges from 53 s to 68 s; 4, the 8-series aluminum alloy (Al-Li) corroded by the etchant solution is cleaned through industrial alcohol; and 5, the 8-series aluminum alloy (Al-Li) is blown and dried.

Description

technical field

[0001] The invention relates to a method for using a novel eight-series aluminum alloy (Al-Li) corrosion solution. Background technique

[0002] The metallographic structure of the eight-series aluminum alloy (Al-Li) is difficult to corrode, and even if it is corroded, the structure is often displayed incompletely. Therefore, the metallographic structure of the eight-series aluminum alloy (Al-Li) is usually observed by anodic coating and polarized light. But this observation method is not only time-consuming, but also increases the production cost. Therefore, how to make the metallographic corrosion of eight-series aluminum alloys (Al-Li) as simple and fast as aluminum alloys is a difficult problem to be solved. Contents of the invention
