Abstract
In this work, the feasibility of ZrC-W composite used as a tool of friction stir welding was investigated by first-principle calculation and mechanical test. A theoretical calculation (including interfacial atomic structure, the work of adhesion of interfaces, density of states and interfacial charge distribution) was performed on ZrC (100)/W (100) interfaces based on the method of the density function theory, and the results show that a strong C-W bond is formed at the interface and ZrC/W interfaces exhibit a mixture of covalent, metallic and ionic characteristic. Furthermore, ZrC–W composite was produced by powder metallurgy method. The composite had a Vickers hardness of 1290HV, and a mass loss rate of 0.046 g/h at 600 ℃, which indicates that ZrC-W has an excellent wear resistance. The calculated and experiment results gained in this study can provide an evidence that the application of ZrC-W composite used as a tool material of friction stir welding is feasible.
