| Summary: | Title screen Hypereutectic silumin is aluminum-silicon alloy. It is widely used as the material for producing pistons and sliding bearings. The samples were obtained in Belorussian State University and in the Physical-Technical Institute of the National Academy of Sciences. The percentage of silicon is 18-20 wt.%. The structure has a large number of pores and cracks. The size of pores is 100 [mu]m. The method of modification have been carried out in two steps. The first step is ion-plasma deposition ZrTiCu coating. The second step is melting the coating into the substrate. After modification microhardness is 3.2 GPa, wear resistance is 1.8 times less than in the untreated samples. The crystallites size is 0,2-0,4 [mu]m. Thus, this method allows to obtain alloys in the near-surface layer, grinding the structure and increasing mechanical characteristics. Режим доступа: по договору с организацией-держателем ресурса |
