The influences of thicknesses of the TiC interface layer and diamond coating on the field emission properties are primarily explored and the ideal combination of annealing temperature and coating thickness is decided.
Carbon coating thickness has evident effects on the mechanical properties of the composites. When the carbon coating thickness was 0 35 μm, the flexural strength was 231 9 MPa. When the carbon coating thickness was 0 55 μm, the fracture toughness was 10 4 MPa·m 1/2 .
To test by gold plate, the measuring deviation is<0.10m, when the thickness of gold membrance and coating is t<0. 3μm. The method is simple and convenient for the controlling production of the coating thickness.
The influences of substrate hardness, coatisng hardne,ss, coating thickness, loading rate, scratch speed and the, friction i state between the indenter ( scratcher) and coatings on critical, load,which cha-
Methods Film coating thickness of Compound Danshen Dropping Pills was scanned by NIRS instrument,the pretreatment methods and wavenumber selection of NIRS were discussed in detail. Partial least squares regress(PLSR) was utilized to build the quantitive calibration model.
Objective Near-infrared spectroscopy(NIRS) and chemometrics were used to develop a nondestructive method for fast detection of Compound Danshen Dropping Pills′ film coating thickness in pharmaceutical process.
For thincoating and thick coating, the coating thickness may be deviate from the real thicknesswhen low diffraction angle peak are used in substrate XRD method, we should use thehigh diffraction angle peak in substrate XRD method;
The carbon steel used in the mixed salt bath which is the mixture of broax and neutral salt for vanadinizing. The purpose is to research the effect that carbon content and holding time do for the coating thickness.
The effect of the coating thickness, the ambient pressure and the temperature of the material on the relative pressure difference is investigated.
Chronopotentiometric study of copper dissolution revealed that the optimum concentration of NH4NO3in the working solution should be in a range from 100 to 200 g/l for reliable coulometric measurements of the copper coating thickness.
The optimization of the electroplating process in drum electrolyzers to minimize the standard deviation of the coating thickness is considered.
A dependence of the shelf life of the material on the coating thickness was established.
