Description
Technical field
The invention mainly relates to field of surface treatment, particularly relate to a kind of bromate Aluminum alloy surface treatment agent.
Background technology
The surface treatment method of aluminium alloy has a lot, such as Physical, chemical method, physical-chemical process and synthetic method.
Existing frequently-used method is anodizing, forms conversion film by electrochemical method in aluminum alloy surface, this
Although method can improve the bromate performance of aluminium alloy, but it adapts to the ability of environment, and conversion film layer is inadequate
Uniformly, easy to fall off, anti-wear performance is not improved, and traditional phosphate conversion and chromating surface
Although treatment technology can obtain good effect, but in the waste liquid discharged in processing procedure containing zinc, manganese, nickel,
The carcinogen such as heavy metal ion and bromite such as chromium, environmental pollution is very serious, and metal surface silane
Change treatment technology is owing to being not related to environmentally hazardous material, and energy consumption in production process is low, technical applications is extensive,
It is considered to be expected to replace phosphate conversion to process and chromating process, is that metal surface individually protects up-to-date
