Tantalum carbide (TaC) gradient composites were fabricated via in-situ fabrication method from the tantalum plate and gray cast iron. The morphology, phase constituents, micro-hardness, and relative abrasion resistance of the composites were analyzed by scanning electron microscopy (SEM), X-ray diffraction (XRD), micro-hardness tester and abrasive wear testing machine. The surface layer, which was ~160μm thick, was dense ceramic layer composed by ~90% submicron TaC particulates. The highest micro-hardness value of the dense ceramic layer was 13.84 GPa. In the sub-layer, the gradient distribution of TaC particulates reflected in the volume fraction decreased from 90% to 0%. While the micro-hardness value decreased from 10.81 GPa to 4.10 GPa. The metallurgical combination of the interface between the composites and matrix was perfect. The wear resistance of TaC reinforced iron matrix surface gradient composites increased significantly.

TiC particulates reinforced iron matrix surface composite was produced by cast technique and in-situ synthesis technique. The surface composite was investigated from thermodynamics, microstructure, wear-resistance and oxidation-resistance. The results show TiC particles whose volume fraction is about 40% exhibit fine size in iron matrix on the surface composite. An excellent metallurgy-bond is observed between the surface composite and the gray iron. Fe-TiC surface composite shows good oxidation-resistance at 900°C and great wear-resistance under condition of dry sliding.

Ceramic particles with high hardness and thermal stability can be used to fabricate in situ carbide particulate-reinforced iron-matrix surface composites with high macro-hardness while retaining high toughness. This paper describes a general process by which in situ carbide particulate-reinforced iron-matrix surface composites with hard ceramic particles are readily formed by a novel in situ synthesis process that combines an infiltration casting process with subsequent heat treatment. The basis of our approach is integrating selected plates of different alloys that can form carbide easily into a metal matrix with a certain amount of carbon such as gray or ductile cast iron by casting to form alloy plates reinforced iron-matrix surface composites. Subsequent thermal treatment of resulting composites leads to alloy elements of plate reacting to the carbon in the matrix to form carbide particles. This approach is applicable to a wide range of materials and morphologies, and can be used in composites and machining tools, as well as in the wear-resistant component industry.
