Abstract

Titanium has extraordinary features of any metallic element such as corrosion resistance, strength to density ratioetc. Due to its good features titanium can be used in the composite as a matrix material. Titanium matrixcomposites (TiMCs) can be used in various industries such as automotive, airplanes and especially biomaterials.Today, as carbon reinforcing material carbon nanotube (CNT), graphite and graphene are used as reinforcingmaterials. The graphene has the most remarkable properties in this reinforced material due to its extraordinarymechanical features, low friction and high abrasion resistance. Composite materials produced by using titaniumand graphene may have remarkable mechanical and microstructural properties. This is conspicuous subject inrecent years. In the present study, graphene (Gr) reinforced titanium composites were produced by powdermetallurgy method. The effect of various percentages of graphene (0-0,15-0,30-0,45-0,60 wt.%) on themicrostructure, density, hardness and compressive strength of Ti composites have been investigated. From themechanical tests after sintering at 1100oC for 120min. The highest hardness and the greatest compressivestrength were obtained for 0,30 wt.% Gr reinforced composites (520.2 HV and 1137 MPa) when compared topure titanium (419.8 HV and 780 MPa). The crystal phase and microstructure of the composites were detectedby scanning electron microscopy (SEM) and X-ray diffractometer (XRD). Better mechanical properties wereobserved for Ti-Gr composite materials when compared pure Ti. These kinds of composites promise the futurefor using especially the field of biomaterials.
