Information × Registration Number 0210U007210, 0108U010829 , R & D reports Title Design of technology producing powders of Cu-Fe-Cr-C and influence of its characteristic properties on creating and properties of electrotechnical and tribotechnical materials. popup.stage_title Head Kirievsky B.A., Registration Date 02-11-2010 Organization Physico-technological institute of metals and alloys National academy of Sciences of Ukraine popup.description2 The purpose (target) of work - research of an opportunity of use of powders from monotectical of alloys on the basis of copper (materials of system Cu - Cr - Fe - С) for manufacturing products electrotechnical assignment for operation in conditions of dry friction, erosion -corrosion of wear process etc. Methods of research: methods optical netalloqraph and electronic microscopy, rengenostructure the analysis. Is shown, that the increase of quantity entered in ligued of pig-iron with 4 up to 8 % increases (its) hardness, the durability wear regigtence at friction in pair with bronze, bulk density of powders grows also. Morphology, distribution of components and the properties regearchine of powders essentially improve their ability to be deformed and to be condensed, that allows to enter into a mix on the basis of this powder more carbon& Because of essential improvement compact copper strenghtening of a powder in structure of a material of plates it is possible to enter up to 10 % of firm greasing as graphite, that it was not possible to make at use of serial copper powders. Alloys the containing powders with the additives Cr - Fe , had on 10 - 15 % above indexes of mechanical properties in comparison with similar materials containing copper powders of the mark ПМС-1. Tests of contact plates made of a copper powder, strengthening hingcromiut by the pig-iron which has been carried out(spent) ОАО ВНИИЖТ, /@. Moscow / have shown their significant superiority under the antifrictional characteristics in comparison with materials ВЖЗП and НЖ2ПБ on an iron base.
