Abstract
Microstructures and properties of TiC metal matrix
composites produced by two different ways were studied.
SHS reaction was utilized in both methods. The casting
material and the coating produced by conventional SHS
reaction was cast bonded together or in-situ reactive
cast bonding was used. In the first method preheating of
coating was used. In the second method exothermic heat of
the TiC formation bonded the coating and cast material
together. It was found that the control of heat and
temperature are in an essential role. In the conventional
cast bonding preheating temperature can cause uneven
contact between the coating and the cast material. In the
reactive cast bonding too much heat from the reaction
makes cast bonding unstable but too low heat cause
insufficient melting and porosity. By careful selection
of the materials and production set-up good quality
coatings were achieved.
