Effect of Mild Steel Particles on the Thermal, Frictional and Wear Characteristics of Ceramic Matrix Composites

Abstract

Micro particles of mild steel, silicon carbide, magnesia and bentonite were employed as input materials in the production of ceramic matrix composites by powder metallurgy. The composites were characterised and they demonstrated desirable characteristics. Sample D containing 12 wt. % of mild steel particles exhibited a very good thermal stability in the temperature range of 0 – 800 0C, high coefficient of friction of 0.59 and reduced wear rate of 2.228 x 10-5 g/m which implies high resistance to wear. 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 resistance to thermal decomposition and wear.
