| Summary: | A Micro-electro-mechanical system (MEMS) gas turbine generator is currently under development. This device uses electrodeposited NisoFezo (thin film) as a structural material in the high speed rotating micro-generator used to convert mechanical energy to electrical energy. For structural applications, the materials' mechanical properties are vital for the design. However, for electrodeposited NisoFezo, currently, there is not any published data regarding its mechanical Properties. Therefore, the goal of this research is to model the mechanical properties of electrodeposited Ni80Fe20 as a function of three critical electrolytes variables: agitation, current density, and temperature. In achieving this goal, a typical off-the- shelf nickel iron electroplating solution was used to fabricate the Ni80Fe2~ test specimens. A 2k Factorial Analysis and Design of Experiments was used to identify the critical variables and boundary conditions, and a new Micro/Nano Testing System was designed and developed to measure the mechanical properties. Finally, a linear regression analysis was conducted to model Young's Modulus and Ultimate Strength as a function of the three critical electrolytes variables. |
