Tungsten alloy application in civil industry including mechanical industry, instrument industry, electricity industry, metallurgy, oil and chemical industry, sport industry, radiation shielding in medical and nuclear industry.

In recent years, nanometered-scale tungsten and its compounds have attracted much focus because of their superior physical and mechanical properties. A wide variety of methods such as mechanical alloying, combustion synthesis, physical vapor deposition (WD), electric wire explosion etc. have been used to synthesize nanostructured tungsten. Among these techniques, mechanical alloying and mechanochemical synthesis (CS) are very attractive. Simple and inexpensive equipments are required, and it can be conducted at ambient temperature. Indeed MCS uses mechanical energy to active chemical reactions.

The welding method of copper bonded tungsten copper electrode is silver brazing, which is the most popular method in our workshop. The silver welding material is used, so that the electricity conductivity can be maintained.

Recently, two-dimensional (2D) nanomaterials has attract a great attention due to its unknown physical, chemical, electrical and optical properties. For instance, graphene nanosheets mechanically exfoliated from graphite show very high carrier mobility, excellent thermal conductivity and optical properties, which inspires lots of other 2D materials such as graphene oxide (GO) , hexagonal boron nitride (h-BN), transition metal carbides and carbonitrides (MXenes), as well as graphitic carbon nitride (g-C3N4) 161 are well studied.
