The Magnesium Treatment Kit contains all the materials necessary to
produce a chromate conversion coating on magnesium alloys.
This coating will conform to SAE AMS-M-3171, Type VI (formerly MIL-M-3171,
Type VI). Additionally, the application method conforms to the requirements
of NAVAIR 01-1A-509.
Magnesium and its alloys are more galvanically active than even zinc
on the galvanic series. Magnesium will form a strong galvanic cell with
every other metal it comes into contact with and is always sacrificial.
When magnesium corrosion is detected, it requires immediate attention
or the corrosion will spread throughout the entire structure. Therefore,
these alloys must be properly protected from corrosion damage.
This conversion coating is sometimes referred to as “Dow 19” and produces a
charcoal gray to gold-colored finish on most magnesium alloys.
This kit was developed specifically for convenient touch-up and corrosion
repair in the field or in repair shops. Ideal for touch-up and repair on helicopter
gearcases and transmission housings and other aircraft components.
Prior to the development of this kit, the chemicals and processes necessary to
perform field repairs on magnesium castings and other magnesium components
were simply not available. Previous instructions had users mixing up their own
formulations from bulk hazardous chemicals which are difficult to obtain in
Specification & Certifications:
