(Physical Vapor Deposition)

Specialty thin films and optical coatingsfor erosion protection and durable anti-reflective coatings

Sputtering and other types of physical vapor deposition are a mainstay of our business. We consistently produce our own sputtering targets and deposit films on numerous substrate materials. A large portion of our work in the sputter deposition realm supports programs for DoD prime contractors and other DoD entities.

Our sputter deposition processing capabilities include:

  • DC and Bipolar Pulsed DC Magnetron Sputtering
  • Low (45kHz) and Medium Frequency (400kHz) AC Magnetron Sputtering
  • RF (2.0 & 13.56 MHz) Magnetron Sputtering
  • Ion Assisted Deposition; DC and AC Substrate Biasing
  • Sample Heating with Various Types of Motion (linear, rotary, etc.)
  • Etch and Sputter Coating of Parts up to 36” Diameter


  • Oxidation Protection of Carbon-Carbon and the Refractory Metals
  • Tailored Electromagnetic Materials
  • Cryogenic Cooler (Rare Earth) Materials Development
  • Laser & Directed Energy Weapon (DEW) Hardening of Composites
  • Functionally Graded Coatings via Co-Sputtering
  • Wear-Resistant Coatings
  • Optical Coatings
    • Anti-reflection
    • Rain erosion protection
  • Electrically conductive coatings
  • Coating of particulate and granular substrates
  • High temperature and corrosion resistant coatings


“I have worked with Exothermics and have known Steve for over 15 years. He was trained as a metallurgist, but has considerably broadened his knowledge to encompass additional spheres of materials including ceramics, ceramic composites, carbon-carbon composites, and associated coatings. He is one of the smartest materials scientists I have had the pleasure of knowing – he is always learning, digs into the literature of the past, and is creative in developing new materials and fabrication approaches.”
