The powder materials for spraying were Ni-22Cr-10Al-lY used for the bond coats and ZrO2-8Y2O3 for the ceramic coats.
For conventional materials, the grain boundary contribution to phonon scattering is thought to be small.
It was found that the thermal conductivity is drastically reduced for fine grained materials, particularly when the grain size is of nanometer dimensions.

INBAR and Hunan University have donated 70 and 50 bamboo structure seismic houses separately [2], which use bamboo plywood as materials for wall.
Considering the impact of non-uniform section, the equivalent area is calculated according to the following formula: (1) Single section’s useful area (1) Where: — the sum of all materials’ sectional area; — sectional area of the nth material

But as a special material, its mechanical characters such as Young’s modulus (E) and Hardness (H) have not gotten much focus on.
Nanoindentation technique is now widely used in evaluating the mechanical properties of small volume materials including thin films for MEMS (micro-electromechanical system) applications [7-9].

Fig.2 shows the influence of lapping load and pad rotation velocity on the workpiece material removal rate.
The two above factors heighten the workpiece material removal rate.

Direct manufacturing cost includes material cost, energy cost and salary cost.
Then, purchase cost () can be expressed as: (3) 3) Relation model between purchase cost and reliability Since direct manufacturing cost (planning, design, test and raw materials) increases as reliability improves, they are closely related with reliability and can be expressed by the function of reliability.
However, limited by technologies and materials, the developed EMU may achieve a maximum reliability () instead of absolute reliability.
