Tribological Properties of TiAl Matrix Self-Lubricating Composites Containing Multilayer Graphene and Ti3SiC2at High Temperatures

“…On the one hand, MLG is believed to be an ideal reinforcement phase to enhance the load carrying capacity of composites due to its outstanding mechanical properties [9,11,13], thus improving the wear resistance of TiAl-MLG and leading to slighter surface damages, as shown in Fig.8. On the other hand, MLG can enhance the thermal conductivity of composites due to its extremely high thermal conductivity [10,25,26], thus resulting in the improvement of the oxidation resistance and the reduction in the amount of oxides on the worn surface of TiAl-MLG, as seen in Fig.8 Detailed microscopic and Raman studies of the worn surfaces for TiAl-MLG after tests are exhibited in Fig.9 and Fig.10 respectively. It can be concluded from Fig.9(a) and Fig.10 MLG-rich films on the worn surface, which is consistent with the above EPMA studies (Fig.6(c)).…”

The improved thermal oxidative stability of silicone rubber by incorporating reduced graphene oxide: Impact factors and action mechanism

“…The thermal stability of polymers such as PP , epoxy composites , and natural rubber , was also investigated, and significant enhancement was observed. However, despite noticeable thermal stability advances made for graphene/polymer nanocomposites, there were few studies involving the use of graphene in silicone rubber material .…”

“…Recently, graphene nanoribbon (GNR) was incorporated into silicone rubber to improve the thermal stability of GNR/SR nanocomposite. As a result, significant improvement was attained due to the homogeneous dispersion of GNR and strong interaction between GNR and SR . Although there are some reports involving the thermal stability of graphene/SR nanocomposites, the improvement was ascribed to the interaction between SR and graphene.…”

Atmospheric chemical vapor deposition of graphene on molybdenum foil at different growth temperatures

“…This material has attracted the interest of many scientists due to its desirable characteristics, including its excellent chemical inertness, atomic smoothness, high mechanical stability, high carrier mobility, current capabilities, and thermal conductivity [1][2][3][4]. A variety of methods have been used to prepare graphene, such as mechanical exfoliation of graphite, epitaxial growth on SiC, reduction of graphene oxide, unzipping of carbon nanotubes (CNTs), and chemical vapor deposition (CVD).…”

“…This method is particularly appealing because it is the most scalable and inexpensive deposition technique [5,6]. Graphene has been deposited via CVD on different transition metals (e.g., Pt [7], Pd [8], Re [9], Ni [10], Cu [3], Ru [11], Ir [12], Co [13], Rh [14], and W [15]), but very few groups have investigated the role of molybdenum (Mo) as a catalyst for graphene synthesis, despite that early studies showed that Mo may act as an effective catalyst for CNTs [16]. Also, using CVD, iron-Mo can act as a very efficient catalyst for the synthesis of single-walled and multi-walled CNTs [17].…”
