But in the actual processing, the formula of the corrosive agent can be improved by experiments(white alumina), so that the corrosion agent can etch the metal at a stable and uniform speed, the surface roughness is reduced by the original roughness, so that the material presents the same structure as that at the beginning of corrosion(green silicon carbide), and the roughness obtained is comparable with other cutting methods.

However, chemical etching is not ideal for the surface finish of castings and forgings, especially for castings, the surface roughness will be higher(brown fused alumina). The percentage reduction will depend on the true surface roughness of the chemical corrosion, for 5.1 um-6.4 um micro coarse accuracy(black silicon carbide). After chemical etching, the original mechanical properties of the metal are affected, which increases with the increase of corrosion degree.(brown aluminium oxide grains wholesale suppliers usa)

After etching to a certain depth, and gradually transits to the typical roughness which is determined by the material structure and properties, heat treatment(black corundum). When the material is constant, the typical roughness heat treatment state and the composition of corrosion liquid have great influence(aluminum oxide abrasive). For the corrosion of structural parts and other functional purposes, the influence on mechanical properties should be studied in depth. 

(brown aluminium oxide grains wholesale suppliers usa)Because in this case, cutting in alkaline corrosive solution has better surface smoothness, but no metallic luster(brown aluminum oxide). If there are cracks, sand holes and other physical defects in the structure of this kind of parts, the mechanical properties will be greatly affected after corrosion(aluminum oxide grit). Before cutting, the surface structure of sand casting parts should be removed by mechanical method before chemical etching.

According to the principle of chemical corrosion, the key to the successful chemical etching of castings is the casting process and the selection of the best corrosion solution formula(pink corundum). If the temperature is high, the reaction is fast and the parts are hanging vertically, it is easy to "seal the tail" on the picture and text when the aluminum alloy is corroded, forming process and etching solution formula(synthetic corundum).(brown aluminium oxide grains wholesale suppliers usa)

If for important structural parts, if the metal corrosion is only for the graphic etching with decorative function, the influence on the mechanical properties can be ignored. The changes of mechanical properties caused by chemical corrosion of metals mainly include: Endurance load, bending property(emery abrasive). After chemical corrosion, the elongation and tensile strength of aluminum alloy are affected, especially the elongation.

Chemical corrosion does not eliminate the influence of these adverse factors(silicon carbide abrasive), the mechanical properties of parts after corrosion will seriously affect the physical properties of parts and cause accidents. The surface state of aluminum alloy after final chemical corrosion has an important effect on the fatigue property of the material, for cast aluminum parts through limited experiments(brown fused alumina bfa grade a manufaturer), fatigue property and ductility of corroded metal.
