MAGNESIUM ANODIZE -A PROTECTIVE COATING FOR MAGNESIUM

    * protects the metal from attack by salt water or other corrosive environments,

    * protects the surface from wear and abrasion.

    * imparts good heat insulating properties.

    * provides high electrical insulating properties to protect the metal from galvanic corrosion,

Magnesium alloy components may be designed, for use in very corrosive environments an/or where abrasion of the applied surface treatment is likely to occur. The anodizing process provides superior protection in the above areas over conventional corrosion protection processes. The process provides a hard anodic coating, that imparts a much more durable surface that resists corrosion, abrasion, wear and heat.

The Magnesium Anodize Process can be used to produce a thin tan colored film or the full chocolate brown colored coating. Anodize film build up beyond the initial thin film is not an even process. Development of the full coating is by outcrop formation, initially near component edges and the gradual filling of general surfaces. This method of film build up serves as a useful visual guide in determining when the treatment is complete. Dimensional increases of approximately .0015 and .003 are typical for the partial and complete coatings respectively. The actual thickness of the full anodize film is approximately double that of the measured increase due to conversion of base metal during the anodizing process.

PLASMA - THERMAL APPLICATION OF POWDERED METALS AND CERAMICS

HOW IS IT APPLIED?

The plasma arc is hot ionized gas composed of nearly equal number of electrons and positive ions passing through an electrical arc. This plasma flame can reach temperatures upwards of 28,000 degrees Fahrenheit. Any powdered material that melts without decomposing, can be introduced into the plasma strewn at a precisely controlled amount. This molten material can be projected against the surface being sprayed at speeds in excess of mach two. The temperature of the base material is kept under 250 degrees Fahrenheit. This process can be performed on heat treated, and hardened parts without causing any distortion or changing of the parent material properties.

HERE ARE SOME APPLICATIONS FOR SPRAY COATING?

SALVAGE: costly, as well as inexpensive parts can be saved by rebuilding a worn or mis-machined area back into dimension. Often this results in a part that will outwear the original by a factor of two to three times.

WEAR COATINGS: coating can be applied to resist abrasion, corrosion, erosion, fretting, friction, and galling. Parts can be manufactured for less money using a low cost base material, and applying a wear resistant coating in areas of need.

WHAT ARE SOME OF THE SPECIAL CHARACTERISTICS?

CHARACTERISTICS: Since plasma sprayed materials can be sprayed on virtually any properly, prepared surface, and using a wide selection of materials, the limitations are almost endless! Coatings can provide such characteristics as: electrostatic or electromagnetic shielding, electrical conductivity, electrical insulation, thermal conductivity, thermal barriers, and many others.

CORROSION INHIBITING SYSTEMS

A MICRO POROSITY SEALANT GUARDING AGAINST CORROSION,

As a protective coating it is particularly effective on magnesium and aluminum alloys. The process can also be used on steel, titanium and other metals. It is highly resistant to weathering and a very wide range of chemicals up to 200 degrees centigrade. Surface sealing enhances the expected life of magnesium alloys by at least 6 times. This enables parts to fly longer in aircraft and thus requiring less down time, which yields a tremendous savings for the end user. The process can be easily applied by centrifuge, spraying, rolling, coating or dipping. Best results are realized when used over an anodized base.

* PROCESS APPROVED FOR COMMERCIAL AND AIRCRAFT APPLICATIONS,
