Summary: | In this paper layered and gradient structures of Ni-Al SHS system were
adopted to manufacture Ni-Al/diamond composites. The effect of the layered
and the diamond mesh gradient structures of Ni-Al/diamond on the SHS process
and the microstructure of the composites were investigated. It is found that
with the increasing of the number of layers, the combustion wave velocity is
decreased. The combustion wave velocity for diamond mesh size gradient
structure of Ni-Al SHS is faster than that for the layered structure. A well
bonding can be formed between diamond and the matrix in layered and gradient
structure Ni-Al/diamond composites due to the melt of Ni-Cr brazing alloy. |
