AnodAM

AnodAM Can Process Your Parts When No One Else Can

The AnodAM process is the best choice when you need to treat any type of magnesium alloy. The AnodAm process does not require preliminary treatments that may cause aesthetic problems during the alloy production process.

The AnodAm process provides a high quality treatment before any type of painting, including E-coat, forming a consistent and adherent layer with a strong affinity to the paint polymers.

Magnesium Benefits

The benefits of our process on magnesium include:

- Mass reduction 75% lighter than Steel; 33% lighter than aluminum- Enhanced design freedom- Parts reduction- Material property advantages over plastic, aluminum, steel- Improved castability- Biodegradable material- Bio-compatible; could replace titanium on implants

The AnodAm Plasma Electrolytic Oxidation Process:

Plasma electrolytic oxidation (PEO), also known as electrolytic plasma oxidation (EPO) or micro arc oxidation (MAO), is an electrochemical surface treatment process for generating oxide coatings on metals.

It is similar to anodizing, but it employs higher potential, so that discharges occur and the resulting plasma modifies the structure of the oxide layer. This process can be used to grow thick (tens or hundreds of micrometers), largely crystalline, oxide coatings on metals such as magnesium, aluminum and titanium.

Because they can present high hardness and a continuous barrier, these coatings can offer protection against corrosion or heat as well as electrical insulation.

Hard Anodizing

Column

Benefits

One of the main purposes of hard anodizing is to make the aluminum more resistant to corrosion. The thicker oxidized layer protects the finished part from being exposed to moisture, oxygen, and other factors. Sealed items are even more corrosion resistant.

Type III “hard” anodizing is done at a lower temperature, is much thicker than Type II, typically .002” vs. .0006” respectively, which makes it more resistant to scratching.

Wear Resistance Hard anodized coatings are more than 10 times more wear resistant than ordinary anodized aluminum.

Heat Resistance Hard anodized coated parts can withstand short exposures of temperatures up to 2000 degrees centigrade due to the inert

nature of the coating.

Electrical Properties Hard anodized coatings are excellent electrical insulators, exhibiting electrical resistance on the same order of magnitude as glass and porcelain.

Column

One-Step Process

Hard Anodizing is an electrolytic passivation process one step used to increase the thickness of the natural oxide layer on the surface of aluminum parts.

Type III anodizing, hard anodizing one step is performed in a sulfuric acid bath containing 180-200 grams per Liter of acid and a small amount of dissolved aluminum. The operating temperature is controlled between 28-32º F
temperatures.

The power supply is a DC rectifier. Current densities can range from 24-40 amps per square foot (ASF),

The aluminum part being anodized is made the anode (or positive pole) in the system. The most efficient cathodes (or negative pole) are 6063t6 aluminum.

Current is applied to the system for a prescribed time, without preliminary steps, at
the desired current density to achieve the oxide thickness required (oxide thicknesses can range from 0.7 mil to 3.0 mils). The resulting porous oxide can then be colored or sealed but limitations on final color will determined by the

oxide produced

Two steps rinses follow the one step anodizing

Coating Properties

Hard coat anodizing or hard anodizing is a process that applies a corrosion resistant coating, chemically bonded to the surfaces of aluminum and aluminum alloy parts or pieces. This creates a surface coating with hardness characteristics second only to diamonds.

Modified hard coating provides lubrication properties that resist abrasion and corrosion, making it the ideal solution for: Pistons, Cylinders, Cams, Gears, Swivel Joints, Hydraulic / Pneumatic Components, applications where metal parts touch or rub each other

Resistance to chemicals, solvents and petroleum based products

Low Friction Coefficient after Lubrication

Technical Advantages

Process cost savings vs. regular hard anodizing processes that use many steps

More environmental process because one step - one chemical solution to dispose.

The faster hard anodizing process: 60 minutes versus 120 minutes

This novel coating technique capable of depositing dense, hard coating on aluminium

and its alloys, has the potential to replace conventional hard anodizing techniques

because faster and better price.

Easier to maintain the process and parts quality.
