Product Description
Alumina ceramic components / relay ceramic assemblies / ceramic - metal brazed contactor
1. Description:
We have proposed an optical method that can be applied to in-process or in situ measurement of the microsurface profile. The present method is based on optically performed spectral analysis and the phase retrieval technique. Spectral information of a surface profile is obtained by measuring the Fraunhofer diffraction intensity. The phase retrieval technique is used to reconstruct the surface profile from the measured spectrum. We have developed an instrument on the basis of the general principles of the present method, and measured the surface of a reference standard having rectangular pockets 44 nm deep at intervals of 10 μm.

In order to select the appropriate material for your application, there are several questions that you should consider.
1) Are the mechanical properties important?
2) Will the part be exposed to wear/friction/impacts?
3) How many pieces are you looking to have made in your first batch?
4) What type of atmosphere will the part be operating in; inert or oxidizing?
5) What is the maximum operating temperature of the component?
6) Will the component experience any thermal shock?
7) Is electrical insulation important?
8) Is thermal conductivity important?
9) How important are tolerances and surface finish?
