Abstract
Efforts at utilizing ceramic materials with their undeniably interesting range of properties in automobile manufacture, has persisted for many years. The corrosion resistance, the resistance to oxidation at high temperatures, the capacity of its resistance to wear and the low relative density of these materials make them especially attractive candidates for use in the automotive engine block production. The limitations of ceramics materials in the area of low fracture toughness can be assuaged by using various methods of grain and boundary size strengthening. This paper presents a critical survey of some of the existing materials used in the production of automotive engine block, the existing methods of toughening and strengthening of ceramic composite materials with emphasis on methodologies, strengths and weaknesses.
