Our Technology

The EPVD® process improves components, making them less susceptible to wear and more tolerant to heat and corrosion. This technology has been awarded numerous US and InternationalPatents and is sustained by unique know-how established over a period of over 30 years. EPVD® is the world’s only industrial technology that replaces galvanic Chrome, and efficiently protects internal surfaces of cylindrical components with proprietary alloys. This environmentally benign technology improves performance, longevity and precision of parts. It allows utilization of a hotter and more energetic operating environment – an obstacle that Cr plating will never be able to conquer. The EPVD® process is suitable for bore diameters ranging from 1/4 inch to 20 inches at lengths of up to 40 feet.

The EPVD deposits any desired materials, including alloys and multi-layered/multi-compositional recipes. Application rates with EPVD® are substantially accelerated, reaching speeds unachieved by any other vacuum-based technology in the world. Most importantly, the EPVD® process is environmentally friendly.

The EPVD® process is a cost-effective process that is quickly replacing past coating methods. Our most important clients are, and will continue to be, government organizations and multinational OGP corporations who require leading edge research, development and engineering services in the most critical areas of production.

We focus on clients
with the following requirements:

System Performance Improvement

Material Replacement

Operating Cost Savings



Wear and corrosion, in their different forms, are the two major and cost bearing side effects in today’s severe operating environment. Aerospace applications are no exception to this decree and a lot of effort is exhausted due to the inability of the aerospace industry to comprehensively deal with these critical elements.

Applications where existing material technologies are no longer capable of meeting ever increasing performance requirements provide the greatest opportunity for improvements via alternative solutions such as coatings. Improvement of conventional technologies and development of alternative coating techniques and materials has always been of great importance to PST. This is especially true for unique applications where traditional approaches have been exhausted.

The industry is in constant need of materials that will replace galvanic chrome and cadmium; as well as industrially sound techniques to apply these new materials to critical internal surfaces of complex-shaped components. Developed and engineered exclusively by Paradigm Shift Technologies Inc., the EPVD™ technology has been exposed to vigorous testing and is currently being engineered for unique use on Landing Gear components of military aircrafts.


The employment of high temperatures and a corrosive environment when processing ethane, nafta and other petrochemical products requires the use of specialized alloy materials compatible within the stringent operating conditions of erosion, oxidation and wear.

Chemical reactions occurring on the inner diameter of the tubulars create an irreparable impact on the metal surface, damaging the material and thus, decreasing the production rates of petrochemical plants. The coating of these tubes introduces a significant performance increase. Engineered EPVD® coatings applied to the inner diameter of tubulars protect the exposed metal surfaces from high temperature and corrosion and increase the throughput of the installation, which transforms into a significant saving if applied industry-wide. The process forms high quality diffusion coatings of multiple materials and/or alloys for extreme chemical environments in upwards of 1200° C.

Surface Engineering for the Ethylene Industry Coking is a large and growing problem in the Ethylene Industry. Coking damages tubes and reduces furnace performance. CoatAlloy™ is an engineered coating system which provides the necessary surface characteristics to mitigate catalytic coke formation. CoatAlloy™ is:

  • Inert top layer
  • Continuous and adherent surface oxide
  • Able to regenerate under pyrolysis conditions
  • Stable at high temperatures
  • Impervious to carbon

CoatAlloy™ coating materials have been strategically coupled with the EPVD® process and employed by PST in its exclusive partnership with Manoir Industries for the use in Steam cracking ethylene furnaces (both gas and liquid) and Process gas heaters of the direct reduction of iron plants.

Tube inner surface coated with CoatAlloy™ utilizing the EPVD® process satisfies the demands of Ethylene service by providing a continuous, adherent inert surface that mitigates catalytic coke formation.

The CoatAlloy™ coatings resist carburization which brings about changes in creep strength, ductility and toughness. They are self healing and have sufficient hardness and toughness to resist erosion by coke particles; they also withstand the thermal shock and cycling inherent in decoking.


PST has been providing its coating expertise to the defense industry by supplying environmentally safe and economically advantageous coating solutions for the improvement of weapons systems.

While working in close collaboration with OEMs and end-users, PST is currently addressing two main areas for the defense industry:

  • Performance improvement of undercarriage components for military aircrafts
  • Life increase in small, medium and large caliber weapon systems
We are a project-oriented company

Each project can involve:

We provide clients with superior service accompanied by state-of-the-art hardware capabilities. We implement a quality assurance and control program for all projects. All project information is tracked using an integrated database management system.

Another important aspect of our services is reassigning developed technical data-packages to our clients; these data-packages are to be used at their respective facilities as an essential part of their manufacturing procedure. Developed coating procedures are licensed and implemented as a sequential step in the overall production process replacing currently utilized techniques.
