Abstract

The invention provides a method for reducing the oxidation speed of a metal product. The method comprises the following steps of: constructing an electrolytic cell by taking a metal sample to be treated as an anode and taking an aqueous solution containing weak acid as an electrolyte; after electrifying for a period of time, powering off and taking out the sample; and (3) cleaning and drying the sample to obtain the metal product. According to the method, the oxidation speed of the metal product can be reduced through quite simple operation, and the surface property of the metal product can bemaintained.

Description

Technical field

[0001] The invention relates to a method for reducing the oxidation rate of metal products, in particular to a method for reducing the oxidation rate of metal products by electrochemical treatment. Background technique

[0002] Copper is a metal with a long history of use and a wide range of applications. It has very excellent thermal and electrical properties, so it has become the preferred metal material for power transmission and electronic device applications. In particular, due to the good match of the copper surface with graphene, chemical vapor deposition can be used on single crystal copper substrates. (CVD) method to prepare graphene. However, compared to gold and silver, copper is also a more easily oxidized metal. It will be oxidized to cuprous oxide and copper oxide at high temperatures, and it will be oxidized to basic copper carbonate in humid air. The earth affects the excellent electrical, mechanical, thermal and other properties of copper. Ther...
