Application No.: 200710186567.2
Name: Surface treatment agent for aluminum alloy and surface treatment method for aluminum alloy
Public (announcement) number: CN101235497
Public (announcement) day: 2008.08.06
Main classification number: C23C22/05 (2006.01) I
Address: Hyogo Prefecture, Japan
Inventor (design): Kobayashi Nobuyuki; Daimiko Takeshi; Ito Hideo
Patent agency: Zhongke Patent & Trademark Agency Co., Ltd.
Agent: Wang Huimin
Summary
Provided are a surface treatment agent for aluminum alloys and a surface treatment method for aluminum alloys, capable of restoring the characteristics of the aluminum alloy surfaces whose aging is deteriorating, and further, even if oils are not recovered after this recovery, and even if temperature and humidity are not controlled In storage under the environment, the properties of the aluminum alloy surface can be hardly deteriorated over time. (1) A surface treatment agent for aluminum alloys for restoring the surface characteristics of aluminum alloys deteriorating over time, which consists of an aqueous solution containing hydrogen phosphate, (2) the concentration of hydrogen phosphate in the aqueous solution 0.01 to 20 g/L. (3) A method for surface treatment of an aluminum alloy in which the surface treatment agent is brought into contact with the surface of the aluminum alloy having deteriorated aging.
