a4. After anodizing the CNC process will be made (as some parts need to provide the electronic contact to the part it has to be done after the anodizing). But how and where will the part be fix in the CNC machine and how do they make sure the surface will not be damaged?[translate...
Historically, anodizing first occurred in an industrial context in 1923 to protect the duralumin parts used in seaplanes from corrosion. Initially, the use of chromic acid was adopted and called the Bengough-Stuart process. Eventually, this led to the adoption of sulfuric acid, which soon became...

To achieve this, the anodizing must be done quickly and under conditions that minimize chemical attack of the oxide coating. This lowers the coating's porosity, which, in turn, Improves its wear resistance. Conventional hard coat is produced in a very cold sulfuric acid bath-usually around 28...
Often, chemicals are used in various processes, such as anodizing metals. Other times, chemicals or breathing hazards are a byproduct of doing the work, such as welding fumes in metal shops or sawdust in woodworking facilities. Adequate ventilation is critical to worker safety in such environments...

specifically 6061. The anodizing is done to various finishes; machine finish, brushed, etc. The problem is blotchy spots and uneven anodizing. From what I've read it may be the grain boundaries being brought out or dendrites. Can anyone give me more information on what is happening and if ...
Metals can be protected by applying a negative charge or applying a coating or anodizing. One useful procedure is to coat the metal surface with paint or enamel, which provides a barrier between moisture and the metal. The coating does not allow direct contact with moisture and metal surfaces....
A 242 mast is normally 36’9” long, and when built in California these long tubes were able to be anodized in large tanks, but Apex’s in-house tanks are only 28’ long, with an effective length of 27’6” due to 1” wide anodizing tank support rack marks being burned onto the ...
anodizing must have included an etch step (hence the semi-bright finish) and a fluoride desmut step which removed much of the silicon at the surface so that the anodized coating is essentially colorless. The anodizing may also have been done to a less than customary thickness to preserve ...
