In China, Tianjin University, Hunan Institute of physics, and Chinese Academy of Sciences Institute of acoustics have all developed mature products in film thickness measurement with a larger scale (above 1mm) has developed a mature product.
Among the layers and plates, the upper plate can be produced by iron nickel alloy material with low temperature coefficient, while the material of inner and outer insulating layers on measuring head is chosen as PTFE, the thickness of which should be as small as possible under the processing conditions permit.
This kind of sensor can be used for the detection of thin non-metallic material thickness, and in dynamic measurement and the static measurement applications.Through precise capacitance calculation, it has been found that additional capacitance caused by the edge effect is large, which has the very big relationships with plate distance and plate thickness.

They still hold the position of one of the most important materials for engineering applications.
With high hardness accompanied by satisfactory toughness [1, 2], WC-Co cermets have been favorable materials against various severe conditions such as wear, erosion, corrosion, etc. [2, 3].
For example, Wentzel et al. [4] and Souza et al. [5] indicated that a Ni binder provides better corrosive resistance than a Co binder for WC materials.

Due to its low density (about 4.5) [1, 2, 3, 4], related with good mechanical properties, titanium and its alloys are superior to other metallic materials [1, 2, 5].

In recent decades the main methods of toughening to ceramic materials are: particle dispersion toughening, fiber toughening and whisker toughening.
Grain boundary and the composition, shape, scale, structure of phase boundary has a great and even decisive influence to the properties of materials.
Compared with metals, the structure, function and theory of grain boundaries and phase boundaries to the ceramic materials is more complex.
