Summary

Titanium diboride fiber which is capable of reinforcing metal matrices at high temperatures has been developed by chemical vapor deposition method on tungsten core. A thermodynamic analysis of the TiCl4 + BCl3 + H2 system has been carried out to determine the operating conditions for the highest equilibrium yield of TiBτ The optimum experimental conditions for deposition are obtained. Surface morphologies of the deposits obtained were studied as functions of substrate surface temperature and concentration of reactants. Crystal orientation was determined by different analytical methods. Effect of thermal stresses on the deposit and a remedy to improve its effect were thoroughly studied. The resultant fibers showed reasonably good properties.
