Investigation on Interface Characteristic of W/Cu Plasma Facing Component
Tungsten coating was fabricated on copper alloy by plasma spraying and its interface characteristic was investigated.The results show that the compliant layers(W/Cu,NiCrAl and Ti) are helpful to reduce W/Cu interface thermal stress,but the most possibility failure position of W/Cu plasma facing component is still in the interface.W/Cu adaptation layer can effectively enhance the bonding strength between tungsten coating and copper substrate by 30%.
