In this work, we have investigated the influence of underlying materials on the formation of bubbles of a-Si.
An inserting layer of SiO2 was introduced in between SiN and a-Si to improve the density of the lower layer material and the adhesion between the two materials.
Two materials, i.e., PECVD-SiN and PECVD-SiO2, are selected as the underlying materials deposited on Si substrates.

For the same hard machining materials, the tool life, the axial distance for cutting and the material removal amount were adopted for the orthogonal test.
Introduction With the advance of science and technology, more and more new materials which include titanium alloy, surfacing material, and ceramics and so on come into applications in cutting edge area[1-3].
The materials for cutting were made by build-up welding, whose hardness is 30HRC.
It is true for materials removing to rough machining.

The crack tip field in functionally graded piezoelectric materials (FGPMs) under mechanical and electrical loadings is studied.
Different from previous analyses, all material properties of the functionally graded piezoelectric materials are assumed to be linear function of y perpendicular to the crack.
Introduction Functionally graded piezoelectric materials (FGPMs) are composites with continuously varying properties that have significant advantages over discretely layered materials.
