COVID-19 Notice: Surface Techniques is currently operating on modified schedule of M-F 6AM to 2:30 pm for shop operations, shipping and receiving, and accounting. Proper formation of an aluminum oxide coating provides the aluminum surface with an increased resistance to corrosion and abrasion. Castings tend to give the anodizer the most problems because of the porosity in the castings and alloying materials used. Over time aluminum naturally forms an oxidized exterior. This application is engineered to provide exceptional lubricity, wear resistance, and high levels of corrosion resistance. He has worked in hardcoat anodizing since 1953 and was involved with many of the process developments. MIL Spec 8625 allows for the use of a sulfuric acid bath under Section 3.4.2.1.

He has never seen a "clear" anodized coating which could meet the minimum requirements for thickness(2.0 mils +-20%) and wear resistance(TWI < 1.5) of MIL-Spec hardcoating. If you are looking for a protective surface coating for your aluminum, this is the process you are looking for. Color can be added, but as the anodized layers thickness increases, the ability to add color decreases. Surface Techniques may be able to anodize per individual needs. This makes it very difficult to anodize alloy 2024. While most surfaces of a part can be anodized, the designer needs to consider the realistic properties of the anodizing process. Hard clear anodizing (Type III Class I) may be processed without sealing.

Hardcoat anodizing is an electrochemical process that creates a controlled oxide film on the surface of aluminum. Each alloy anodizes differently because alloy metals change the conductivity of the part and cause it to form aluminum oxide, either faster or slower. 35 Maple St. Lowell, MA 01852. Hardcoat may only be required on one surface of the part. This oxide layer is extremely porous and hard. If the aluminum is dyed (Class II), black is the most commonly used color. This process produces a thicker layer than conventional anodizing. If you have questions or want further info about our processes, call us today at 800.398.0790 or email us at [email protected] Val-Kro also offers both Conventional and Hardcoat Anodizing using our proprietary anodizing line.
