1000 is a proprietary (U.S. Patent #7,070,833), multilayer sili-
con, chemical vapor-deposited (CVD) coating, specifically designed to
improve the corrosion resistance of steel, stainless steel, alloys, glass,
and ceramics. The unique non line-of-sight CVDprocess produces a
flexible amorphous silicon layer that diffuses into themetal lattice. The
layer will conform to themost intricate surfacewhilemaintaining high
dimensional tolerances. Silcolloy1000will deformwith tubing surfaces,
allowing leak-free seals or radius bends.
Methods available to control industrial corrosion are limited to
corrosion-resistant alloys, barrier coatings, cathodic protection, and
corrosion inhibitors.When properly applied, eachmethod can be
effective in slowing corrosion, but each has limitations aswell.
For example, some coatings are inexpensive, but require rigorous
inspection and/or frequent reapplication. Corrosion-resistant alloys
can provide exceptional protection, but can be prohibitively expensive.
Some alloys require significant process redesign, increase operating
cost, or generate hazardouswaste. Silcolloy1000 is the solution to
high cost corrosion issues.
Independent LaboratoryTesting
Silcolloy 1000offers an order of magnitude ormore improvement in
corrosion resistance relative to existingprocesses.
Corrosion testing of Silcolloy 1000 treated 316L stainless steel and
untreated316L steel according toASTMG48, MethodB2 (72-hour
ferric chloride pitting and crevice corrosion testing), show corrosion
of the treated stainless steel is reducedby an order of magnitude, as
measuredbyweight loss (Figures 1 and 2). 1
