IDEA #97DNYO Materials For Electrical Contacts And Electrodes, Which Uncontents Of Noble Metals

SCIENTIFIC INNOVATIVE PROJECTS FROM ACADEMY OF TECHNOLOGICAL SCIENCES OF UKRAINE MATERIALS FOR ELECTRICAL CONTACTS AND ELECTRODES, WHICH UNCONTENTS OF NOBLE METALS Description Scientific(cid:28)Production Enterprise "GEKONT" was devel(cid:28) oped of industrial electron beam technology of producing of materials for electrical contacts, which have no ana(cid:28) logues in world practice. The materials on a basis Cu and Mo, not containing extremely scarce Ag and W, receive by high(cid:28)speed electron beam evaporation and subsequent condensation of the mixed steam flow in vacuum on the substrate, heated up to determined temperature. Previously put dividing layer provides easy branch con(cid:28) densing of a material from a substrate. The composite materials for electrical contacts also are let out according to TU U20113410.001(cid:28)98. Today "GEKONT" successfully is delivering electrical con(cid:28) tacts for many enterprises of Ukraine, Russia, Southern Korea, China, Czech, Romania, Poland. Innovative Aspects and Main Advantages The new contacts surpass in durability known on Ag base (W(cid:28)Ag, Ag(cid:28)CdO, Ag(cid:28)Sn) in 1.5…3 times and at the same time they in 2.2…2.5 times is cheaper. – increasing terms of durability of contacts; – decreasing of contact's cost; – decreasing of contact's service's term; – possible to repair old contacts. Areas of Application Electrical contacts of devices (relay, contactors, actuators, shuters etc.), electrodes of machines contact welding, spring electrocontacts and membranes. Stage of Development Materials was patented (Patents of Ukraine № 34875, # 17204А) and certificated (TU U20113410001(cid:28)98,TU U31.2(cid:28)20113410(cid:28)003(cid:28)2002) Already on the market, commercialized. (made more then 1.5 mln. electrocontacts). Contact Details: Academy of Tehnological Sciences of Ukraine Contact person: Dr. N.
