Abstract: High chromium cast irons are widely used in many engineering practices where wearresistance is required. This paper studies the effect of titanium concentration on thewear behaviour of slightly hypoeutectic high chromium white cast iron. Otherapproach was investigated by adding other carbide forming elements such asmanganese and molybdenum as a combination of two and three elements. The aimis mainly to see the influence of these elements on the toughness of the matrix, thesmoothness of the structure as well as the wear properties of this kind of cast iron.Results, discussed in terms of the wear behaviour, shows that lower volume loss isseen for the sample having higher titanium content (3% Ti). This explains thattitanium proeutectic carbide is the first phase precipitation during solidification whichcontributes to a reinforcement of the matrix. The formation of these carbidesconsumes parts of the carbon present in the alloy so that during eutectic solidificationthe volume of eutectic carbides diminished. The addition of manganese andmolybdenum gives less important results.
