Widely applied in manufacture, ship and chemical industry.Industrial economy is developed rapidly, to the demand day of Welded structural member
Benefit increases, and the Research on Weldability for enabling aluminum alloy to also is goed deep into therewith.Current aluminium alloy is using most alloys.
To improve the use quality and outward appearance of aluminum alloy surface, need to be processed by shot blasting.Polishing refers to using machinery, chemistry
Or the effect of electrochemistry, reduce workpiece surface roughness, the processing method to obtain light, flat surface.It is using polishing
The modification processing that instrument and abrasive grain or other polishing mediums are carried out to workpiece surface.Polishing can not improve the size essence of workpiece
Degree or geometrical precision, but for the purpose of obtaining smooth surface or bright luster, be also used to eliminate gloss (delustring) sometimes.
Generally using polishing wheel as polishing tool.Polishing wheel is typically folded with multilayer canvas, felt or leather and formed, both sides round metal
Board clamping, the polishing agent that the coating of its wheel rim is uniformly mixed by micron power and grease etc..Chemical polishing is that metal surface leads to
Cross regular dissolving and reach bright smoothing.Surface pore, cut and other surface defects can be filled in chemical polishing, so that
Improve fatigue resistance, corrosion resistance.Mechanical polishing.Mechanical polishing is grinding, the rolling effect by very tiny polishing powder,
Remove the very thin layer of metal on sample flour milling.
Chemical polishing and mechanical polishing cut both ways, if chemical polishing is compared with the polishing suitable for complex surface, but to gold
Metal surface has certain corrosiveness；And mechanically polish and be more suitable for big and flat surface, but mechanical polishing can bring one
Determine the sub-surface damage of degree.
