SEO TEC

Equipment and technologies for electron-beam and ion-plasma treatment of materials

The production and commercial company Sumy Electron Optics (SEO) works in the field of creating research equipment and vacuum technology for various fields of science and technology.

Using the modern equipment, new technologies and proprietary software products, the SEO firm carries out the following activities:

Using the modern equipment, new technologies and proprietary software products, the SEO firm carries out the following activities:
Designing and manufacturing of vacuum ion-plasma coating plants by various methods: electron beam (EB-PVD), arc-arc (Arc-PVD), magnetron sputtering (MS), ion beam (IBAD according to customer's specification).
Designing and manufacturing of vacuum installations for ion-plasma nitriding of machine parts. Modernization of industrial installations НШВ-28.7 / 6-И1, НШВ-9.18 / 6-И2, etc.
Design and manufacture of vacuum installations for the application of optical coatings (antireflection, interference, etc.).
Modernization of vacuum ion-plasma equipment (electric arc and magnetron sputtering plants) - Bulat-6, Bulat-3, NNV-6.6, MAP-1, VU-2M, VU-2MBS, etc.
Manufacture of units for vacuum ion-plasma deposition plants (cathode nodes, magnetrons, ion sources, gas leakage, etc.)

Vacuum installations of ion-plasma coating provide the application of functional wear, heat, erosion, cavitation and corrosion-resistant coatings on machine parts, application of nanostructured wear-resistant coatings on the tool: cutters, drills, including small ones (∅up to 1 mm), punches, dies, plungers and the like.

The manufactured vacuum equipment is designed and manufactured in full compliance with modern requirements for industrial vacuum installations. This is a modern element base and the most complete realization of technological capabilities of equipment due to automation of the process technology.

The ability to adapt to customer requirements is an important virtue of our company. We are ready to offer solutions that exactly match the customer's specifications, including unique engineering developments.

Almost any solution for the formation of thin films and coatings can be integrated into our equipment, while we can use the best components from market leaders, be they automation devices or vacuum components. The choice of equipment - for the customer.

All vacuum units are equipped with an automated process control system (ASUTP), which has undergone many years of industrial testing in the conditions of various serial productions. This allows us to solve typical tasks of the automated process control system - process technology for a given program, equipment diagnostics, emergency situations, creation and archiving of working protocols, and also to work in "manual mode".

The application of this system ensures the stability and repeatability of the properties and characteristics of the sprayed coatings and nitrided products from batch to batch meeting the current world level.

Especially it should be noted that we ourselves are developing software for our installations. If the majority of competitors order software on the side, which slows down its debugging and refinement and raises the cost, then we always equip the equipment with optimal software reliability and functionality.

In the case of equipment modernization, we perform not just a restoration, but a deep modernization of the spraying plants. Obsolete and exhausted components are replaced, including electronics, electrical equipment, separate technological modules. From the old installation, in fact, only the frame remains.

The equipment is equipped with modern software, and in terms of its capabilities, it is almost as good as new models of the same class, while the savings for the customer are very significant: the cost of the restored equipment can be 2 to 3 times lower than the new one with comparable characteristics. Restored plants are guaranteed.

The delivery of the equipment may include services for training the Customer's personnel and technological support of the equipment.

Below in the appendix the information illustrating some developments of installations of ion-plasma and electron-beam spraying is given.
