How can aluminum round bars be treated for anticorrosion?

The corrosion behavior of 6063 aluminum round bar caused by silicon can be completely prevented and controlled. As long as the raw material and alloy components are effectively controlled, the proportion of magnesium and silicon is within the range of 1.3 to 1.7, and the parameters of each process are strictly controlled to avoid segregation and dissociation of silicon, so as to make the silicon and magnesium as beneficial as possible. Mg2Si strengthening phase. 

 

If this silicon corrosion point is found, special attention should be paid to the surface treatment. In the process of degreasing and degreasing, the weak alkali slots are used as much as possible. If the conditions are not allowed, the time of soaking in the acid deoiling liquid should be reduced as much as possible (the qualified aluminum alloy profiles are placed in the acid degreasing liquid from 20 to 30min, but there is no problem. " The profile of the problem can only be placed 1 to 3min), and the pH value of the washing water in the future is higher (pH>4, control Cl- content), and the corrosion time is prolonged during the alkali corrosion process. The light liquid should be used in the neutralization of light, and the electrooxidation should be used as soon as the sulfuric acid anodized, so that the dark grey corrosion point caused by silicon is caused. Not obvious, can meet the requirements of use.
