초록
The objective of the present study is to investigate the increase in the functional characteristics of asubstrate by the formation of a thin coating layer. Thin coating layers of Ti5Si3 have high potential because Ti5Si3exhibits high hardness. Shock induced reaction synthesis is an attractive fabrication technique to synthesize uni-5Si3 using shock induced reactionsynthesis, were mixed using high-energy ball mill into small scale. The positive effect of this technique is highlyfunctional coating layer on the substrate due to ultra fine substructure, which improves the bonding strength.These materials are in great demand as heat resisting, structural and corrosion resistant materials. Thin Ti5Si3 coat-ing layer was successfully recovered and showed high Vickers hardness (Hv=1183). Characterization studies onmicrostructure revealed a fairly uniform distribution of powders with good interfacial integrity between the pow-ders and the substrate.
