Ti film could be deposited on the CoSb3 substrate by magnetron sputtering.
No crack was found at the region of Ti/CoSb3 interface in the coated CoSb3 sample after accelerated thermal aging test.
The bonding of Ti coating with CoSb3 substrate was well after accelerated thermal duration test.
Ti coating could suppress the sublimation of Sb in CoSb3 at high temperature effectively.
