【 摘 要 】
In this paper a study is conducted on the abrasion wear behavior of iron matrix composite materials, testing of samples obtained by sintering was made for different values of the applied load as for the relative speed of sliding. Starting from the studied literature, recipes of sintered sintered metal composite materials having iron matrix have been developed which have been tested for their physico-chemical and tribological properties. The prepared powders were dosed according to the formulations (Fe 68%, Cu 13%, Ni 5-7%, Graphite 6%, SiC 8%, SiO 2 8%), and the resulting mixtures were homogenized to achieve homogeneous mixtures to ensure, finally, a good reproducibility of the physico-mechanical properties of the sintered material. For forming, a cylindrical die having a surface area of 2cm2 was used. Working pressures ranged from 5000 ÷ 6000daN/cm2. The densities obtained for the compressed samples were determined by weighing the METTLER analytical balance and measured with the micrometer for the volume calculation. The values of raw" densities range from 5.12 to 6.3g/cm3.【 预 览 】
