Corrosion resistant aluminum processing after analysis

Source:Dongguan Foxron Precision Metal Parts Co., Ltd.Update:2013-12-31

    In general, aluminum processing after the corrosion of aluminum form is varied.
    A metal tip shape formed by the pitting corrosion, galvanic corrosion is when aluminum contact with other metals, aluminum anode in a state of accelerated corrosion.
    Exists in the clearance of the corrosion caused by difference gas cell gap within the corrosion speed up ten times or more in vain.
    Caused by the incomplete heat treatment is not flourishing in the intercrystalline pure aluminium corrosion is also very common problem
    Silk membrane in the form of corrosion, corrosion development, in the form of filaria aluminum material loss of surface luster, pulverization, and decreased the mechanical properties of the aluminum.
    Corrosion of several different forms.
    A little hole corrosion forms, corrosion in the form of the tip of the metal corrosion, dot, hole corrosion state only partial corrosion.Aluminum in the atmosphere, fresh water and neutral solution of water quality, will accelerate the corrosion time, more bad is probably forming punch.
    Corrosion holes may eventually stop developing, corrosion energy is under a limit value.Corrosion is a unique form of anodic reaction, is an autocatalytic process.
    Electric dual corrosion is one of the characteristics of aluminum corrosion state of the natural potential of aluminum is negative, when aluminum contact with other metals, aluminum products always in the extreme anode it would only make aluminum corrosion time speed up more times.
    Two kinds of metal corrosion morphology, the severity of the corrosion is made up of two metal potential relative to location decision in a sequence.
    Clearance corrosion is due to the differences in gas cell, accelerates the gap in corrosion, and clearance won't have too big effect, clearance in corrosion and alloy type.
    Aluminum alloy is very resistant to corrosion, but even aluminum alloy also have crevice corrosion.Crevice corrosion in recent years for more in-depth research, the mechanism of acid corrosion status is at the top of the original capacity.
    Intergranular corrosion is pure aluminium is not prosperous intercrystalline corrosion, this pure aluminium corrosion is also very common problem, alloying elements or     intermetallic compound along the grain boundary precipitates out, relative to the grain as a corrosion cell anode, intergranular corrosion caused by acceleration.
    Silk membrane in the form of corrosion, corrosion development, in the form of filaria oxidation film can also be applied on the paint film, also can make the other layer and does not generally in a state of anodic oxide film below.
    Aluminum after processing, the surface of aluminum oxide layer won't fade, will not fall off, easy to maintain, strong aluminum corrosion resistance, can long endure the Marine climate, while satisfies the requirement of wind pressure, no color, no corrosion.
