Corrosion Protection By Chromate Conversion

Chromate Conversion on Houston like Alodine or Iridite is a chemical treatment for aluminum used to present corrosion protection and also surface preparation for paint and other adhesives.

Chromate is a superb treatment for paint or adhesives as it greatly enhances the product's ability inorder to form a bond with the aluminum.

It is often used on electrical and electronic equipment as it provides increased corrosion resistance even as remaining electrically conductive.

The oxide film formed by this process varies in color, depending on the aluminum alloy that is being treated, surface conditions, and type of chromate. The key benefits of alodine are.

1. It resists corrosion.

It is indicated that the alodine treated surface withstands corrosion in a five percent of salt spray test for 168 hours. Results vary depending on the alloy of the material and surface finish.

2. Alodine is an outstanding paint base.

As the coating is not applied electrically and could be applied quickly, alodine is one of the most cost effective methods to provide a appropriate primer base prior to applying a paint.

3. It is decorative.

Alodine have a light gold to dark gold appearance depending on your personal preferences.

Importance Of Electroplating

Electroplating means deposition of a thin layer of metal to a work piece using an electrolytic process. Electroplating is useful in automotive industry for chrome plating and in electronic industry for optics and sensors. The purpose of electroplating is - appearance, protection, special surface properties and engineering or mechanical properties. All the electroplating finishes are of extremely high quality. Zinc plating, nickel plating, chrome plating and copper plating are just a few examples of CA metal plating chemicals. Nickel coatings have a decorative appearance, corrosion protection, ferromagnetism properties, and wear resistant. The properties of tin coatings are - good appearance, solder ability, nontoxic, corrosion protection, and low friction. The applications of electroplated tin alloys are electronics, semiconductors, food containers, packages, and engine applications. The applications of hard chromium electroplating are industrial rolls, plastic molds, cutting tools,...

Traditional Anodizing To Prevent Corrosion

The practice of anodizing, or the controlled oxidation, of aluminum and its alloys are more than seven decades old. The main intention behind anodizing aluminum and its alloy parts is to guard the highly reactive surface against corrosion in aqueous environments, like moist air and sea water. Since the anodic coating could be produced in a range of colors, the painted parts are generally used in architectural applications. Further, as the process of aluminum anodization on CA would produce a hard ceramic covering, harder than that of the substrate from which it is formed, the anodic coatings are also used to shield aluminum parts from abrasions, especially sand abrasion. Traditional anodizing process is electrochemical oxidation. The part which is to be anodized is then connected to the positive terminal of a Direct Current (DC) power source and a non reactive metal, like stainless steel, is coupled to the negative terminal. The aluminum anode, and the stainless steel cathode are...

Use Of Hard Anodized Aluminum

Anodized aluminum has light weight. It is used mostly for industrial purpose. It is 30% harder than stainless steel. This has a long life span. Even in high heat level the anodized finish will not be damaged because it has a melting point of 1,221 degree f. Aluminum cookware is processed through hard anodized aluminum. It is useful for many industries like automobile industry, commercial cookware, and medical field. This is a bit more expensive than regular anodized aluminum. Anodize can be done at home with the help of sulfuric acid. Hard anodized aluminum is used because it has non toxic finish, cleaned easily, does not wear easily etc. It is available in many colors but mostly black is used. Hard anodized aluminum does not stick on the surface of the cookware. If you have any queries relating to Chicago anodizing chemicals or IL anodizing chemicals just visit our site.
