摘要
Abstract
Using the method of immersion static corrosion and electrochemical test,the corrosion behavior of Cu alloy and its action mechanism in different immersion time were studied.The results show that the corrosion rate decreases gradually with the increase of immersion time,the color of the surface corrosion layer of copper alloy gradually changes from purple to red,brown and yellow to dark green.Early corrosion product is Cu2O,and then Cu2O and CuO with the increase of corrosion time.Continue to increase corrosion time,the corrosion product film is continuously thickened,and the Cu2O in the inner surface reacts with the Cl in the solution to form Cu2 (OH)3C1.The dense and uniform corrosion product film can inhibit the corrosion reaction to a certain extent,and the corrosion rate decreases gradually.关键词
