The Stress Analysis of ZrO2/Ni Symmetrical Functionally Graded Materials
Based on the classical lamination theory and thermo-elastic mechanic to overcome the tendency toward microcracking during preparation process, the thermal stress relaxation design and structure optimization of ZrO2/Ni symmetrical FGM with and without stainless steel substance are carried out in this paper. The results show that it is very difficult for us to fabricate thick non-crack ZrO2/Ni FGM coating/stainless steel substance workpiece. And just non-crack the ZrO2/Ni symmetrical FGM without stainless steel substance can be fabricated while the compositional distribution exponent n and the thickness of pure Ni layer is more than 3.6 and 2/3, respectively. And the pure Ni layer is the weakness of the ZrO2/Ni symmetrical FGM. This suggests that it is a suitable way to improve the performance of ZrO2/Ni symmetrical FGM and to make it possible to fabricate ZrO2/Ni symmetrical FGM with stainless steel substance by means of improving the properties of Ni exist in FGM.
