Abstract

In this study, TiC /Ti powder functionally graded materials (FGMs) were prepared to be used in general engineering applications, such as space and aerospace industries , biomedical, electrical ,etc. A traditional powder technology has been used successfully in producing these materials.
Thermal conductivity, hardness and wear resistance are evaluated for each set of materials that produced in this work. The hardness numbers variation proves the gradation of properties across the layers of each type of FGMs.
It was found that, Brinell hardness numbers are changed in each layer of produced FGMs according to the percentage of the harder constituent (TiC) where the result shown that the value of Brinall hardness for sample A face (2) which contain 7.5 Ti & 92.5 % TiC (332.62) and (254.77) for face (1) which contain 18% Ti & 82% TiC , either sample B face (2) which contain 20 % Ti & 80 % TiC (290.84) and (167.51) for face (1) which contain 40% Ti & 60 TiC . Wear resistance was improved also according to the increasing of TiC percentages, where the loss for sample A face (2) has been ( 0.0035 , 0.0019 , 0.0017 ) respectively with time increase, and for face (1) has been (0.0012 , 0.0020 , 0.0021) respectively with time increase, either for sample B face (2) loss weight to was 0.003 , 0.013 , 0.023) and for face(1) ( 0.016 , 0.021 , 0.029) .
