SilcoTekSurface Treatments
We offer surface treatments that enhance
performance inmany applications:
A corrosion resistant
layer that increases the lifetime of system
components in acidic environments.
Greatly reduces
outgassing from components of ultra-high
vacuum systems.
A general-purpose
passivation layer for steel and stainless steel.
The ultimate
passivation for treated components, from
glass to high nickel alloys of steel.A required
treatment formetal componentswhen
analyzing for parts-per-billion levels of
organo-sulfur compounds.
Dramatically reduces
carbon buildup on stainless steel components.

Coatings
Pathways in semiconductor process
systems require high corrosion
resistance, lowmoisture content, and
highpurity. The current substrate of
choice in semiconductormanufactur-
ing, electropolishedVIM/VAR
(vacuum inductionmelt/vacuumarcmelt)
316L stainless steel, fails toperform
inmany demandingprocess environ-
ments. The result is increasedperiodic
maintenance, prolonged equilibration
times, system contamination, and
inaccurate analytical results.
SilcoTek’s patented non-line-of-sight
chemical vapor deposition (CVD)
processes produce a highpurity, #ex-
ible, amorphous silicon layer, diffused
into thebasemetal lattice. The layer
will conform to themost intricate sur-
face. TheSilcoTek
®
surfacewill deform
with tubing surfaces, allowing radius
bends and leak-free seals.

1000 treatment improves
corrosion resistanceby up to 10x over
untreated 316L stainless steel (Figure

Improve reliabilitywhile reducing
costsby up to 65%!
316Lgas delivery systems exposed to
corrosive environments typically are
replacedwithin5 years of installation.
Substituting a highperformance alloy
for 316L stainless steel can increase
the cost of the systemby asmuch as
$ve-fold.

By improving the corrosion resistance
of 316L stainless steel by up to 10x,
Silcolloy1000 treatment reduces
costlymaintenance and $eld failures
due to system corrosion. Figure 2
compares the cost of Silcolloy1000
treatment versusHastelloy™C22

ery system. Silcolloy1000 treatment
demonstrates signi$cant life-cycle
cost savings, compared tounprotected
stainless steel or stainless steel alloys.
