The results of project work were a developed and patented an active flux for welding. The active flux changes the characteristics of welding arc and weld pool and enables quicker, more productive and cheaper welding. The advantage of developed flux is its friendliness to the environment and human healthcare. Based on the results a company for development, production and commercialisation of the product was established.

COBISS.SI-ID: 13048859Spajanje z gnetenjem je tehnologija, ki se intenzivno razvija od patentiranja leta 1991 na Britanskem inštitutu za varjenje. V industrijski praksi je najbolj razširjena uporaba FSW tehnologije za spajanje gnetnih aluminijevih zlitin. V zadnjem času se raziskave osredotočajo tudi na spajanje dveh različnih zlitin. Spajanje z gnetenjem ima velik potencial tudi v livarski industriji, še posebej pri tlačnem litju. Ta članek opisuje izvedeno eksperimentalno spajanje dveh različnih zlitin. Spojeni sta bili gnetna zlitina AA1050 in livarska zlitina AA413.0. Taki spoji imajo svojo uporabno vrednost pri sestavljenih ulitkih, kjer lahko s spajanjem različnih zlitin z različnimi fizikalnimi lastnostmi dosežemo nehomogene lastnosti sklopa, kjer je to potrebno. S spajanjem tlačnih ulitih delov lahko izdelamo sklope z notranjimi votlimi deli. Lastnosti tako izdelanih sklopov so primerljive z lastnostmi tlačnih ulitkov. V članku so navedene temperature, izmerjene med spajanjem dveh različnih zlitin. Za določitev optimalnih parametrov spajanja je bilo leto izvedeno pri različnih vrtljajih orodja in pri različnih hitrostih spajanja. Spoji so bili mehansko analizirani. Stacionarno temperaturno polje med spajanjem dveh različnih zlitin je bilo izračunano s programom Sysweld z metodo končnih elementov.
F.09 Development of a new technological process or technology
COBISS.SI-ID: 1264991Current work elaborates possibilities for direct conversion of AlMgSi1 aluminium chips into solid billets by solid state recycling. Milling chips from an aluminium alloy were cold compressed in a closed cylindrical die by means of a 2,5 MN hydraulic press. Due to low initial relative density of the chips, several precompressions were needed. In order to establish the influence of chip geometry on the final density of billets different types of chips were cut by using various milling regimes. The influence of a compression regime due to various chip types were followed by load–stroke diagrams. Up to 97 % of density measured at extruded aluminium was attained for one type of chips. Results show that the shapes of the chips and their size (especially thickness) have a considerable influence on the final integrity of compressed billets.

COBISS.SI-ID: 12342299PROTAC 500, an armoured plate for the pose of NATO, represents a world-class product, made of new generation of steel. Its primary purpose is to protect the lives and property of both natural and legal persons or entities. It has excellent mechanical properties, including standard technological characteristics, such as good tensile properties, excellent impact strength at low temperatures, hardness and deflection as well as ballistic testing, where the PROTAC 500 armoured plate is made sccording to NATO standards as it has lower required thickness of protection in comparison to the competition. The reduction of required thickness affects the mass and is of great importance especially for vechicles with an integrated PROTAC 500 plate, as accordingly, it ha san important energetic and environmental aspect. The PROTAC 500 armoured plateh as a good flexibility for bending and may be welded. While developing the steel, only the advanced technology of self-tempered martensite was used, which makes it possible to manufacture the PROTAC 500 armoured plate with a single treatment.
F.06 Development of a new product
COBISS.SI-ID: 1510751Subject of the invention is a chemical composition of an alloy for electrical contacts and the method for its synthesis. Electrical contacts made from this alloy, according to the invention, are preferentially made for the low-voltage systems or electrical contact assemblies (starters, alternators). The copper-based high performance alloy for electrical contacts and the method for its manufacture is ecologically safe and includes the processes of continuous casting, crystallization, homogenization, quenching, and subsequent precipitation annealing in a protective atmosphere of inert gas (argon). The alloy of the invention has less than 0.01% by weight of the impurities and the amount of chemical elements by weight: 0.4-0.8% Ni; 0.2-0.4% Fe; 0.1-0.3% P; the rest copper, reach hardness of ) 140 HV and has a specific electric conductivity of )73% IACS.
