That’s why it’s smart to design a place on your part which can be used for holding but which won’t be adversely affected cosmetically. Wherever the holding fixture touches the part, that area will be blocked and the anodizing chemicals won’t work properly. Holding a part in position requires that it be mounted on a hanger of some kind to keep it from falling to the bottom of the tank.

Why is it Impossible to Anodize an Entire Part?Īnodizing requires that a part is immersed in a series of chemical baths. That’s why it’s so commonly used in architectural fittings, because it’s both beautiful and almost impervious to the effects of weathering. It’s inexpensive, reliable and eminently durable. Anodizing also works with magnesium, titanium and even conductive plastics. Can Materials Other Than Aluminum Be Anodized? This causes the distinctive shine of aluminum anodizing. So the light that bounces back to strike your eye will in fact be a combination of two distinct wavelengths interacting as they reflect from slightly different surfaces. Light changes colors as it reflects from an anodized surface. When aluminum is exposed to the atmosphere it quickly forms a layer of aluminum oxide on the surface, and this layer provides a degree of protection against further corrosion. And oxygen is very reactive, readily forming compounds with most other elements. What is oxidation? It simply means to react with oxygen. Does Aluminum Need Corrosion Protection?Īlthough aluminum doesn’t rust, it can deteriorate in the presence of oxygen, which is called oxidation. This takes more time and is more expensive but produces a superior result. This is produced by continuing the electrical current until the depth of the pores exceeds 10 microns, all the way to 25 microns or even more. Hard anodizing, sometimes called Type III, offers greater corrosion protection and resistance to wear in extreme environments or with moving mechanical parts subject to a lot of friction. Aluminum oxide is rated 9 out of 10 on the Mohs hardness scale, meaning second only to diamond. That will leave you with a hard, natural aluminum oxide coating, able to withstand chemical attack and very scratch resistant. Once this level is reached, and if no color is needed, the process is stopped and the surface can be sealed simply by rinsing in water.

For typical non-hard coatings, the depth can be up to 10 microns. The longer the current is applied the greater the penetration of these columns. This is called a barrier layer, a defense against further chemical reactions at those spots.Ī regular pattern of surface porosity is created when electric current is applied. The aluminum at the surface combines with the negatively charged O 2 ions to create aluminum oxide. These pores form a geometrically regular pattern and begin to erode down into the substrate. The electrochemical reaction causes pores to form on the surface of the aluminum as excess positive ions escape.

The electric current in this circuit causes positive ions to be attracted to the negative plates, and negative ions to flock to the positive anode, the piece of aluminum. An electrolyte is an electrically conductive solution with lots of positive and negative ions that it wants to swap.Ī positive electric charge is applied to the aluminum, making it the “anode”, while a negative charge is applied to plates suspended in the electrolyte. To prepare aluminum for anodizing, the surface is first thoroughly cleaned and rinsed, and then placed into a bath of some electrolytic solution like sulfuric acid. Anodizing is one of the most durable surface treatments 1.
