Application of SHS in the Manufacture of (NiAl/Ni3Al)/TiB2 Composite

Abstract

Abstract The aim of this study was to demonstrate the advantages and the method of application of the SHS process in the manufacture of (NiAl/Ni 3 Al)/TiB 2 composites. A comparison was made between sinters manufactured by FAST/SPS using two different routes to process the substrates, which formed the composite matrix. The evaluation criteria were based on measurements of selected physical, mechanical, and tribological properties, and on microstructure examinations. The evaluation has indicated a preferable method for the manufacture of composites, where the SHS reaction takes place during compaction of the powder mixture. This produces a sinter characterized not only by the high degree of sintering, and high values of the Young’s modulus and HV1 hardness, but also by the satisfactory resistance to tribological wear. Additionally, the use of this process saves energy and reduces product-making cost, owing to a less expensive technique of making individual substrates.
