Summary

A series of producing process of a functionally gradient material (FGM) by self-propagating high-temperature synthesis (SHS) process have been developed and TiB2-Cu based FGM was fabricated by the process. Using the automatic powder spraying and stacking device, raw material powders were sprayed and stacked on Cu substrate so that the compositional profile can be graded as non-linear as fitting the material design after synthesis. This stacked body was compressed and vacuum-sealed into the capsule for the synthesis. The FGM sample was ignited and compressed with synthesizing simultaneously under high-hydro pressure of 58 MPa. As a result of this process, TiB2Cu based FGM of 1 mm thickness and 30 mm diameter can be produced on Cu substrate.
