Fabricating Graphene-Titanium (<30μm) Composites by Powder Metallurgy Method: Microstructure and Mechanical Properties

Abstract

Titanium has the most useful properties of the metal are corrosion resistance strength-to-density ratio, the highest of any metallic element. In its unalloyed condition, titanium is as strong as some steels but less dense. Due to its good features titanium can be used in the composite as a matrix material. Titanium matrix composites (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 reinforcing materials. The graphene has the most remarkable properties in this reinforced material due to its extraordinary mechanical features, low friction and high abrasion resistance. Composite materials produced by using titanium and graphene may have remarkable mechanical and microstructural properties. This is conspicuous subject in recent years.

In the present study, graphene (Gr) reinforced titanium composites were produced by powder metallurgy method. The effect of various percentages of graphene (0-0,15-0,30-0,45-0,60 wt.%) on the microstructure, density, hardness and compressive strength of Ti composites have been investigated. From the mechanical tests after sintering at 1100oC for 120min. The highest hardness and the greatest compressive strength were obtained for 0,30 wt.% Gr reinforced composites (520.2 HV and 1137 MPa) when compared to pure titanium (419.8 HV and 780 MPa). The crystal phase and microstructure of the composites were detected by scanning electron microscopy (SEM) and X-ray diffractometer (XRD). Better mechanical properties were observed for Ti-Gr composite materials when compared pure Ti. These kinds of composites promise the future for using especially the field of biomaterials.
