A range of standards apply to alodine, chromate conversion and chem-film processes used on Aluminum and Magnesium alloy components: MIL-DTL-5541 Type 1 covers military standards for hexavalent Chromium processes; 4. This type of chemical conversion coating aluminum also complies with the MIL-DTL-5541. Anodize vs Alodine (Chem Film) Alodine is a trade name for chemical conversion coating of aluminum (also called “chem film” or “chemical Chemical Films are also known as chem film, alodine, iridite, chemical conversion coatings, or chromate conversion coatings. Types of Bearings: A Complete Guide. 0012” for Type II) compared to paints and powder coat. Subsection 1: Most anodizing on machined parts are of two commonly specified types: Type II (or “regular”) sulfuric anodizing and Type III Hardcoat or “hard” sulfuric anodizing. While there are a number of accepted standards for applying alodine coatings on aluminum, MIL-DTL-5541 by the U. Alodine 600, 1100 and 1200 series coatings from Henkel Hi Having some Tiger stripe issues with my alodize process. However, the most consumed types of chem films are MIL-DTL-5541 (Type I and Type II). Its listing on QPL- 81706-16 indicates its acceptance under MIL-C-5541E. In brief, chromic acid anodizing is used for thin coatings where loss of fatigue strength would be a major issue (such as in aircraft components); but most anodized coatings are done in sulfuric acid. A cheaper alternative to anodizing, Alodine coatings can be used to enhance the passivating oxide layer on the surface of aluminum products, improving corrosion resistance. Military; Automotive; Appliance; Aerospace; Furniture; Specifications. According to their different chemical composition and properties, Alodine coatings can be classified into various types, with the most common being Type 1 and Type 2 according to the MIL-DTL-5541 standard. Status Not open for further replies. Alodine 1200 is a commonly used treatment that forms a protective layer on aluminum surfaces. On the other hand, Alodine (chem film) does not require passing an electrical current on the aluminum. In fact, there are quite a few types of the chemical conversion coating. Understanding the chemical process behind Alodine is crucial to grasp its effectiveness as a protective coating. Alodine. Alodine vs. Alodine is a chromate chemical film coating for metals that enhances the part’s corrosion resistance, strength, surface adhesion, etc. MIL-DTL-5541 Type I, Class 1A and Class 3. Alodine Coating Types. We will introduce the definition, working principle, main characteristics, types, advantages and disadvantages as well as applications of Alodine finish Alkaline cleaners remove organics, followed by a rinse and deoxidation before applying the Type 2 Alodine solution. 2. Unlike passive coatings such as paint or powder coat, Chromate conversion coatings, aka chem film or Alodine™, and anodizing are commonly used on aluminum parts. Types Of Alodine Chromate Conversion Coating. Type 1 coatings primarily contain hexavalent chromium, hence often referred to Alodine finish is a type of aluminum alloy surface finishing, which is mainly used to improve the corrosion resistance of aluminum parts, as well as to enhance the adhesion of the metal, and is a good substrate for painting. It was the most chosen and safest type of Alodine coating until type 2 Alodine Types and Classes. For chromate conversion, see MIL-DTL-5541, which covers Type I (older and more dangerous using hexavalent chromium) and Type II (more current and safer non-hexavalent chromium option) and the different classes.
