Armoloy®
TDC is a low-temperature, multi-stage metal finishing process
improved from chrome-plating technology.
Unlike
conventional chrome-plating processes, Armoloy®
utilizes proprietary chemical solutions and unique application
techniques that are carefully monitored to produce its TDC
(thin dense chromium) coating which follows the exact contours
of the basis metal with accurate deposit thicknesses.
Value-added
benefits of Armoloy® TDC Coating:
- Reduced
wear and friction of moving parts
- Enhanced
corrosion resistance
- No
chipping, cracking or peeling from the basis metal
- Improved
release characteristics on plastic molds
- Reduced
maintenance and machinery replacement costs
- Smoother,
faster and quieter running equipment
- 78
Rc surface hardness
-
Vickers Diamond measurements produce a 1020-1100
hardness rating.
- Complies
to AMS-2438a (10/98) -
And Others
Low
Friction Coefficient:
Armoloy® is a low friction
coating due to special techniques used in its application.
The low coefficient of friction is invaluable especially in
situations where extreme temperatures are involved.

Normal
proven average deposits are in the .0001/.0003" per side
range.
Less
Hydrogen Exposure:
Armoloy's® unique processing
and preprocess surface preparation minimizes a parts exposure
to hydrogen. (Original conditions may not, necessarily, be
removed.)
Resists
Corrosion:
Armoloy® resists attacks by most organic
and inorganic compounds with the exception of sulfuric and
hydrochloric acids.
Of
course, base metal porosity, surface hardness and other imperfections
affect basic corrosion-resistant properties.
Conforms
to ASTM-B117 and others.
Armoloy®
Takes the Heat:
Armoloy® withstands temperatures of -400º
to 1600º F.
At
elevated temperatures above 1200º F it will react with carbon
monoxide, sulfur vapor and phosphorous. At bright red heat,
oxidation occurs in steam or alkali hydroxide atmospheres.
Hardness
and wear resistance will be reduced, to some degree, at temperatures
above 1200º F.
Safety
First:
With Armoloy's®
strength also comes safety.
USDA/FDA
compliant for use on food processing equipment and pharmaceutical
applications. |
