In the work, the characterization of 1mm W coating on copper alloys by means of vacuum plasma spraying technology was investigated, which included microstructure, thermal properties, mechanical properties and the chemical composition. W coating shows the low porosity of 7.6% and the thermal conductivity of 79.7W/mK at RT. The bonding strength of about 45MPa was obtained. These results are interesting for plasma spraying W coating used as plasma facing material. Besides, the gas desorption property of W coating was performed. H2 was the gas species with the largest desorption rate, then H2O. The gas desorption rate remarkably decreased after baking for 4 hours at 300oC, and it became not much change after further baking. Therefore, it can be concluded that tungsten coating used as plasma facing material is feasible.
