Achieving superior tribological properties of GNPs reinforced Ti6Al4V composites via interface structure design

The severe interface reaction, which has been a challenging problem in graphene nano -platelets (GNPs) reinforced Ti6Al4V (TC4) matrix composites, results in poor mechanical and tribological properties. Herein, GNPs/TC4 composites exhibited excellent wear resis-tance by introducing the in-situ TiB whiskers (TiBw) on the interface between GNPs and matrix. This work highlights the mechanical and tribological properties of GNPs/TC4 composites by diminishing the interface reaction and strengthening the interface bonding through the in-situ formed TiBw.(c) 2023 Published by Elsevier B.V.
