Copper-based Metco™ 57NS, Metco 58NS,
Amdry™ 500C and Amdry 500F are inert gas atomized, alloyed powders developed to protect metal-to-metal wear of
titanium alloy parts. Coatings made from these materials are
dense, low in oxide content and reduce wear by fretting, adhesion, galling and cavitation.
Metco 58NS, Amdry 500C and Amdry 500F contain indium,
which improves the anti-galling and lubricity characteristics
of the coating.
Near surface wear properties can be improved with the
addition of a dry film lubricant applied to the coating surface
after spraying.
Typical Use and Applications
- Turbine engine blade roots or disks slots to resist fretting
and galling wear
- Expansion joints or compressor air seals
