  1. Innovations in Microarc Discharge Oxidizingtechnologies Prof. Boris L. Krit K.E. Tsyolkovsky «MATI» - Russian State TechnologicalUniversity Technologies of Materials Treatment by High Energy Flows Department www.tompve.ru tel: +7-495-3538334, fax: +7-495-3538372, e-mail: tompve-2005@yandex.ru

  2. Microarc Discharge Oxidizing (MDO) Modification by nano-ceramic synthesis on metal surface

  3. Metal’s behavior in electrolytes Valve metals (Al, Mg, Ti, Ta, Nb, Zr, Be, Hf, W, Bi, Sb, U)exhibitsthe valve effectwith forming AOF in metal-oxide-electrolyte system a – non-valve metals processes on the anode Chemical-thermal treatment b – valve metals Anodizing & MDO

  4. Anodic-cathodic MDO process A C High temperature and pressure in discharge channels, rapid cooling T2000-8000 К P106Pa, v106 К/с E l e c t r o l y t e An- Am- OH- O2- . E l e c t r o l y t e H+ Men+ Men+ Mem+ M e t a l M e t a l A – anodic half-period C – cathodic half-period

  5. Structureof MDO- proceedingsurfaces Multylayered composite material: 1 – transitive layer 2 – functional layer 3 – technological layer 3 2 Surface of metal before MDO 1

  6. Comparative indicators of MDO Technology: *ГОСТ 27597-88 (Russian state standard)

  7. Scheme of the MDO equip and proceeding Flow diagram under MDO Object of proceeding 1 – electrolyte bath;2 –water cooling;3 – bubbler; 4 – electrolyte;5, 6, 9 – valves; 7 –filter; 8 –water pump; 10 –heat exchanger (cooler); 11 – object of proceeding; 12 – air compressor; 13 –exhaust umbrella; 14 –exhaust fan; 15 – technological power supply Preliminary cleaning (washing to degreasing) MDO Rinse after treatment Drying Ready made products

  8. Experience of the equipment implementation • Moscow State Industrial University, Russia (60 kW) • Joint-stock company «ENA», Russia (100 kW) • R&D company «Orion», Russia (200 kW) • Penza polytechnic institute, Russia (60 kW) • Beijing central R&D institute of Mining and Metallurgy • «BCRIMM», China (100 kW) • Beijing XIN OU Science & Technology Development • Co., Ltd., China (100 kW) • Hauzer Techno Coating, Netherlands (100 kW) • HPB, International Water Technology, Austria (100 kW) • Belgorod State University, Russia (60 kW) • Joint-stock company Cryogenmash», Russia (100 kW) • National Research Centre«Kurchatov Institute», • Russia (60 kW) • Gebze Institute of Technology (GYTE), Turkey (100 kW) • MOFRA group, France (60 kW) • Saratov electro instrument-making factory name by • Sergo Ordzhonikidze, Russia (100 kW) • FSUE «Ufa Device Production Association», • Russia (100 kW) Technological power supply (TPS) Electrolyte bath (reactor) Automated TPS Automated technological line

  9. Fields of MDOapplications

  10. Parts of water and vacuum pumps Microarc oxidizing of fast-rotating parts for immersed water and oil-free lamellar vacuum pumps

  11. Lapped end - face consolidation for compressors Parts of disintegrators (mills)

  12. Flowmeters and metering devices of liquids and gases Engine pistons

  13. Details of aerospace devices

  14. Pneumatic/hydraulic systems for aerospace craft

  15. Parts of textile machines

  16. Construction, build industry and devices’ cases

  17. Results of the Mg-base alloy bike frame corrosion testing Changes caused by corrosion in external and internal surfaces of magnesium raw material Changes caused by corrosion in external and internal surfaces of MDO-treated supporting fork NSS testaccording ISO 3768, «AGMI Material Testing and Quality Control Co.» (Hungary)

  18. Medical applications Coxofemoral jointimplants Orthopaedic implants Handle of medical tools Nippers, tweezers

  19. Prospectsof MDO-proceeding & equipment(according to Baker Tilly Audit investigations) Appeal of the target markets Exit barriers on the market

  20. ($ mln)

  21. Many thanks for your attention! Conclusion: Total capacity of surface modifications market ~ $30 bln Promising of the MDO market rising ~19% & of the MDO equipment market rising ~25% till 2015 MDO is at an early stage of industrial development and has the perfect future!
