High Temperature Coatings

Protect Equipment and Improve Reliabilty 

Maintain Process Performance and Stability Even at High Temperatures

SilcoTek® offers CVD coating solutions engineered for demanding high temperature environments. Our coatings help components withstand elevated temperatures while resisting oxidation, corrosion, chemical attack, and fouling that can reduce performance and shorten equipment life. Get the right coating solution for your application and operating conditions.
 
SilcoTek's coating process bonds a thin, uniform barrier to the surface of stainless steel and other alloys. Unlike conventional coatings that can chip or flake, SilcoTek coatings become part of the surface, providing long-lasting protection and reliable performance in applications where high heat is an ongoing challenge.

High Temperature Stability

The Silcolloy® 2000 process allows customers to experience high-temperature stability in their applications. The amorphous silicon layer avoids oxidation at high temperatures to improve and prolong performance. 

  • Better coating adhesion and performance at high temperatures 
  • Excellent thermal stability 
  • Prevents oxidation at elevated temperatures 
  • Helps maintain clean surfaces in semiconductor, energy, and chemical processing equipment

Uncoated vs. Silcolloy 2000-coated 316L SS coupons were thermally exposed to 600, 700, and 800°C for 6 hours in air first, followed by coating strip to reveal the SS substrate. The oxygen content listed under each sample was obtained via EDS analysis; BDL stands for "below detection limit" which is 0.1% for the EDS analysis. The SL2000-coating SS maintained its original silver sheen whereas the uncoated SS oxidized heavily, highlighting the exceptional oxidation resistance of SL2000.

High Temperature Performance

SilcoTek's coatings increase performance in high-temperature environments. Using our coatings you can expect: 

  • Maintains consistent process performance at elevated temperatures
  • Improves equipment reliability in demanding thermal environments
  • Reduces oxidation-related process variability
  • Helps minimize fouling and carbon buildup
  • Preserves corrosion resistance during high temperature operation
  • Extends service life of critical components
  • Reduces downtime caused by heat related surface degradation
See The Data
The anti-coking properties of SilcoTek coatings allow for continued performance long after uncoated parts would have failed.
