Abstract

Micro particles of mild steel, silicon carbide, magnesia and bentonite were employed as input materials in the development of ceramic composites by powder metallurgy method. Varied formulations were used in producing the samples and they were characterised. The samples demonstrated desirable characteristics. Sample D containing 12 wt. % of mild steel particles exhibited density of 1.78 g/cm3, water absorption of 0.3 %, hardness of 137.15 BHN, compressive strength of 146.38 MPa, and impact energy of 6.64 J. Proper blending of constituent materials and strong bonding enhanced the characteristics of the composites. The results indicated the suitability of the composite for use in fields that require high compressive strength and hardness.
