LIU Rui, WANG Hong, TANG Jun, et al. Study on mechanical properties of Ni-W alloy films in micro-electro-mechanical system[J]. 2009, 28(8): 46-48. DOI: 10.13873/j.1000-97872009.08.005.
The mechanical properties of Ni-W alloy films electrodeposited in the system of citrate amine-HEDP are sdudied.The testing chip is fabricated with UV-LIGA technology and measured by uniaxial micro-tensile system.The gauge section of Ni-W thin film specimen is 5μm×50μm×100μm.The results show that the Young’s modulus of Ni-W film is about 100.4GPa
tensile strength is about 1.96GPa and strain is about 3.6%
