Titanium plate surface shading techniques

Coloring treatment of titanium and  Xinnuo titanium alloys  : titanium and  titanium alloy  surface is silver , with excellent corrosion resistance , titanium if you want to perform a variety of shading . About three titanium coloring method in three ways: atmospheric oxidation, anodic oxidation, chemical treatment . Now the most commonly used is the anodic oxidation. We will be a test to intuitively understand the anodic oxidation. First, now with the solution. The aqueous solution was distilled with sulfuric acid, the sulfuric acid concentration is low , less than 1:10. Begin to make experiments with waste titanium , titanium anode , cathode with a thick copper wire when , put together the above electrolyte. Through the power after the bubble began to take . OK OK after the beginning of shading , coloring into the aqueous solution of  titanium and titanium alloys  . Specified voltage 15V, one begins to wonder how long you want energized , so to say , " as long as possible ," the right piece over 10 minutes , pay attention to look at, the aqueous solution of copper sulfate solution slowly turns blue , but the result is far from ideal. Later, in addition to redo it grinding , the surface polished , polished , re- energized 15V, electricity about 2 minutes, pretty much . After this test that, in order colored uniform look good, we must first carefully grinding surface , using with 800 sandpaper , good surface is very smooth. Also found that the process is powered anode processing, power outages can first look deal with the situation , and then decide whether or not to continue energized. There is an interesting phenomenon , anode cathode copper melting went to go .
