SURFACE-ALLOYED CYLINDRICAL, PARTIALLY CYLINDRICAL OR HOLLOW CYLINDRICAL COMPONENT |
摘要 |
A surface-alloyed cylindrical, partly cylindrical or hollow cylindrical component consists of an aluminium matrix casting alloy (1) and a precipitation area (3) extending as far as the surface of the component (3) and consisting of an aluminium base alloy with precipitated hard phases. A eutectic area (2) (hereafter: "transition area") which is supersaturated by primary hard phases is present between the matrix (1) and the precipitation area (3) and the increase in hardness from the matrix (1) to the component surface (3) is gradual. |
