DVTI: Coating technology for the future

Our vision

Directed Vapor Technologies International, Inc. (DVTI) uses the unique properties of Directed Vapor Deposition (DVD) to create newly possible coatings solutions, thus enabling our customers to extend the potential of their core technologies.

DVTI continues to advance the potential of directed vapor deposition and usher in a new generation of coatings and coating applications. The DVD technology has the capability to deposit thin and thick films, using controlled compositions and architectures, at a high rate onto complex components. The result is a low cost processing approach for creating engineered surface coatings that are often difficult or impractical to produce with conventional techniques.



DVTI's state of the art 3 generation DVD coater

The DVD III is a production capable coater whose vacuum chamber measures 3ft x 3ft x 6ft, with the potential to easily coat complex objects up to 15in x 15in x 15in. Specialty objects such as tubular structures as well as reel-to-reel tapes exceeding 15 in. can be accommodated with adjustments. DVD III is intended to evaluate production techniques and prove customer specific concepts. It is also designed for production operations. The source material is melted in three 1" diameter actively cooled copper crucibles by the continuous mode 60KW electron gun capable of multisource beam scanning. Other melt pool designs are available with a minor reconfiguration. The high operating voltage of 75KV allows the beam to work at high chamber pressures, further increasing the available deposition parameter space. The fully computer controlled operation allows for repeatable deposition campaigns at a low cost per run.
