Anodizing increase the thickness of the natural oxide oxide layer on the surface of metal. Metal parts are treated forms the anode electrode of an electrolytic cell so the process is called anodizing. Anodizing increase resistant to corrosion and wear. It offer better adhesion for primers and glues. Anodic films is used for many effects. For example, cosmetic effect with thick porous coasting which can absorb dye and cosmetic effect with transparent coasting which add reflected light wave interference effects. Anodic films are commonly applied to protect aluminum alloys. Anodizing process exist for titanium, zinc, magnesium, niobium, zirconium, hafnium and tantalum. Anodizing changes the microscopic texture of the surface and the crystal structure of the metal. Thick coating are porous normally. So a sealing process is usually need to achieve corrosion resistance. Anodized aluminum surface are harder than aluminum but have low to moderate wear resistance which can be improved with increasing the thickness or by applying sealing substances. Anodic films are stronger than most types of paint and metal plating. At&nbsp;<a href=\"https:\/\/www.teamrapidtooling.com\/\" target=\"_blank\" rel=\"noopener\"><strong>TEAM Rapid<\/strong><\/a>, you can use our anodizing aluminum service to enhance the functionality and appearance of the metal parts. Anodizing can be done on a wide range of materials. Today, we will talk about anodizing aluminum. Here is the eight things you need to know about anodizing aluminum.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-is-the-aluminum-anodizing-process\" style=\"font-size:25px\"><span id=\"How_is_theAluminumAnodizing_Process\">How is the\u00a0Aluminum\u00a0Anodizing Process<\/span><\/h2>\n\n\n\n<p>When to prepare aluminum for anodizing, make sure the surface is cleaned and rinsed. And then place it into a bath of some electrolytic solution like sulfuric acid. How does the <a href=\"https:\/\/www.wikihow.com\/Anodize-Aluminum\" rel=\"nofollow\">anodizing aluminum process <\/a>work? When is the process is ongoing, a positive electric charge is sent through the aluminum and a negative charge is applied to plates in the electrolyte. How the An electrolyte is an electrically conductive solution. A positive electric charge is applied to the aluminum to make it anode. A negative charge is applied to plates which are suspended in the electrolyte. The electric in circuit create positive ions to be attracted to the negative plates. The electric in circuit create positive ions to be attracted to the negative plates. And negative ions to flock to the positive anode.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-barrier-layers-in-anodizing-aluminum\" style=\"font-size:25px\"><span id=\"Barrier_layers_in_Anodizing_Aluminum\">Barrier layers in Anodizing Aluminum<\/span><\/h2>\n\n\n\n<p>The electrochemical reaction causes pores to form on the surface of the aluminum because excess positive ions escape. The aluminum at the surface combines with the negatively charged O2\u00a0ions to create aluminum oxide. This is the barrier layer which defense against further chemical reactions. The pores will continue to penetrate deeper into the substrate. For non-hard coatings, the depth can be more than 10 microns. When this level is done, if it is no need to add color, the process is stopped and the surface can be sealed by rinsing in water. You will get the hard and natural aluminum oxide coating which withstand chemical attack and scratch resistant.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" style=\"font-size:25px\"><span id=\"Types_of_Anodizing\">Types of Anodizing<\/span><\/h2>\n\n\n\n<p>Aluminum parts can be anodized using different methods depending on the required appearance, durability, corrosion resistance, hardness, and cost.

Oxygen is reactive. When the aluminum parts is exposed to the atmosphere, a layer of aluminum oxide is formed on the surface which protect against corrosion. Aluminum withstand more than just pure water and air. Acid rain, salt water can exploit weaknesses in the surface.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\" id=\"h-how-to-have-color-aluminum-anodizing\"><span id=\"How_to_have_Color_AluminumAnodizing\">How to have Color Aluminum\u00a0Anodizing<\/span><\/h3>\n\n\n\n<p>Colored aluminum is increasing need when it comes to anodizing. The pores etched into the surface are ideal for introducing tints or pigments. The pigment fills the empty pores up to the surface. Anodized colors are durable. The color can not be scratched off from the surface as the colors are deep down. It can be removed only by grinding away the substrate.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><a href=\"https:\/\/www.teamrapidtooling.com\/cnc-machining-services-t-19.html\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" src=\"https:\/\/www.teamrapidtooling.com\/uploadfile\/userfiles\/image\/20210914\/20210914142406_75417.jpg\" alt=\"Color Aluminum Anodizing\" title=\"Color Aluminum Anodizing\"\/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\" id=\"h-anodized-aluminum-has-metallic-sheen\"><span id=\"Anodized_Aluminum_has_metallic_sheen\">Anodized Aluminum has metallic sheen<\/span><\/h3>\n\n\n\n<p>After adding color to the anodized aluminum, it has a characteristic of metallic look.

As anodized aluminum parts are abrasion resistant and corrosion resistant, they are suitable to be placed in harsh environment. It also provide thermal insulation to metal products. Anodizing aluminum process makes metal parts last longer than raw parts. The the coating is thinner than paints and powders. Anodizing aluminum parts have eco-friendly finish, it is recyclable.
