[ OUR TECHNOLOGY ]
[ Performance & Characteristics ]
By utilizing controlled plasma, the Al2TEO process remelts the surface of soft valve metal into corundum, instantly 'quenching' it in the electrolyte. The resulting dense crystal lattice of the alpha-phase, paired with an ultra-fine grain structure, provides the coating with its signature diamond-like hardness.

We have conducted a series of rigorous stress and impact tests on the Al2TEO coating — evaluating its resistance to impact, abrasion, and wear — to clearly demonstrate the limits of its durability. The test results prove that our technological solutions provide maximum protection for components and assemblies where conventional materials fail.

TECHNOLOGY IS BEING USED IN AEROSPACE PROGRAM
Our subsidiaries operate as autonomous centers of excellence, transforming scientific breakthroughs into market-ready products. Today, the Group is represented across three core technological sectors:
[ our projects ]
[ pyrohgen group ]
HEALTHMONITOR
High-tech gas analyzing device, conducts a quick test on human body status by measuring the concentration of gases in exhaled air.
Pyrohgen
The first mass production of ultra-high purity graphene nanomodifiers (CNO). The synthesis technology ensures economic benefits for large-scale implementation in the real sector.
Al2TEO
The AL2TEO® technology is an innovative method for forming ultra-hard protective ceramic (corundum) coatings using thermoelectrochemical oxidation (TEO). This coating is applied to so-called "valve" metals, which include aluminum, titanium, and magnesium alloys.
We offer flexible engagement models — ranging from low-risk initial testing to full-scale production deployment:
Custom Coating Services.
The customer sends a batch of parts — we apply the coating using our operating equipment and ship them back. This is the lowest-risk format to evaluate the technology in action.
Pilot Production Line.
A compact system designed to refine and validate production parameters for a specific customer product — for instance, a single piston component line or a specific part size.
Turnkey Industrial Line.
Delivery of a mass-production line complete with commissioning, staff training, process recipe transfers, and a five-year warranty.
Localized Assembly under Supervision.
A portion of the equipment is assembled at the customer's site or by a local partner to reduce costs. Critical components, including the power supply and software, are supplied and maintained exclusively by us.
[ Partnership formats ]
[ Testing Phase ]
Core concept
You send a batch of your parts, we apply the corundum coating using our operational production equipment, and return them to you.
Advantages
This is the lowest-risk format, allowing you to evaluate the technology and conduct real-world lifecycle testing of the parts without upfront capital expenditures.
Timeline
The testing phase typically takes 4 to 8 weeks.
[ Coating as a Service ]
[ Premium orders ]
Core concept
A format designed to optimize and reduce overall project costs. Parts of the standard equipment and infrastructure are assembled directly at your facility or by a local partner according to our specifications.
Technology Control
The most critical and technologically complex components (the power source and software) are exclusively supplied, configured, and maintained by us.
[ Localized Assembly ]
[ compact installation ]
Core concept
We supply a compact installation (approximately 100 kW capacity) to refine the production process for a specific customer product (e.g., a single piston size).
Specifications
The maximum load area is ~10 dm², requiring a facility space of at least 80 m², and is operated by 1 employee per shift.
Purpose and Timeline
The pilot phase lasts 3 to 6 months. It is designed for processing a batch of parts, conducting lifecycle testing on your end, and developing an accurate economic justification before scaling.
[ Pilot Production Line ]
[ serial production line ]
Core concept
Complete delivery of a serial production line, which includes an integrated hardware-software complex with its own power source. All technological modes tailored to your products are pre-configured by our engineers and hardcoded into proprietary software.
Configurations
Available in basic (320 kW, load ~32 dm²), medium (500 kW, load ~50 dm²), and specialized factory (600 kW for long-length products) setups.
What is included
Transfer of technological know-how, commissioning, personnel training, a 5-year warranty, and long-term scientific support.
Timeline
Contracting and design take 2 to 3 months; manufacturing, delivery, and launch take an additional 6 to 9 months.
[ Turnkey Industrial Line ]
[ Exclusive Engagement ]
Core concept
Deeper integration models, which can include the establishment of joint ventures or acquiring licenses to replicate production lines across multiple locations.
Conditions
These strategic formats are discussed individually during the later stages of collaboration, strictly following the successful completion of a pilot program.
