摘要

In order to study the resistance mechanism of materials having high resistance to impact-abrasion, synergistic effect of subordinate phases of 2.20 wt%C-3.45 wt%Cr-3.06 wt%Mn-1.32 wt%Si-0.51 wt%Cu-0.31 wt%Ni-0.002 wt%B cast iron was investigated under dry impact-abrasion. Subordinate phases consist of graphite, secondary precipitates and retained austenite. Results show that the synergistic effect of above subordinate phases can prevent matrix and carbide from peeling off, and minimize the damage of carbide to matrix. This effect reduces the depth and width of groove from 7 to 1.2 mu m and from 14 to 2.5 mu m respectively. Above significant improvement is owing that: (1) Graphite can disperse external/internal stress, and fill carbide peeling pits. (2) Secondary precipitates, such as [Fe, Ni] and [Cr, Ni], can disperse the concentrated stress of carbide, inhibiting peeling. (3) Retained austenite can disperse the internal concentrated stress which is transferred from the carbide and fine precipitates to matrix. Graphic
