Information × Registration Number 0204U006964, 0103U003511 , R & D reports Title Investigation of manufacturing and wear resistance of porous slide bearings made from materials produced in Ukraine popup.stage_title Head Laptev A.M., Registration Date 11-01-2005 Organization Donbass State Engineering Academy popup.description2 The subject of investigation is sintered powder bearings of iron - copper - graphite system. The goal of work is the determination of influence of copper powder type on technological parameters of production and wear-resistivity of slide bearings. The influence of usage of different copper powders on shrinkage of compacts during sintering was investigated. The influence of copper powder type and porosity of compacts on quality of oil impregnation was determined. The influence of copper powder type on microstructure and phase composition of sintered parts was investigated. The influence of copper powder type on hardness and wear resistance of powder bearings was studied. Recommendations on replacement of foreign copper powders by Ukrainian ones were formulated Product Description popup.authors popup.nrat_date 2020-04-02 Close
