Aluminum AlloysLynntech, Inc., College Station,
Texas

• Innovation
• A molybdate-based conversion coating for aluminum
  and aluminum alloys as an environmentally benign
  replacement of chromate-based conversion coatings.

• Accomplishments
• Development of an inorganic molybdate conversion
  coating that does not contain chemicals or
  materials that are hazardous, toxic, or give rise
  to health and safety concerns.
• Successful demonstration of protection for
  greater than 336 hours during salt fog exposure,
  according to MIL-C-81706, for a wide range of
  aluminum alloys.
• The molybdate conversion coating can be applied
  by dipping, painting, or spraying, with short
  treatment times at low temperatures, and is
  compatible with existing cleaning and
  pretreatment procedures.
• Only commercially available chemicals and
  materials are used, which do not require special
  storage provisions and can be easily adapted into
  existing application methods.

• Government/Science Applications
