Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This revised standard adopts ISO 9220. 1988 "metallic coating thickness measurement scanning electron microscope."
This standard and ISO 9220. 1988 main technical differences are as follows.
--- Control ISO 9220. 1988 (9.2.1.2), this standard uses photographic imaging output. Due to technical development, the Standard is a modified meter
Computer disk record store the image and calibration. ISO standard relates to video signal waveforms present device is not used, this
Standard with a resolution higher EDS line scan technology.
--- Normative references Replace the corresponding country standards, and increases the GB/T 27788-2011 of reference.
The standard proposed by China Machinery Industry Federation.
This standard layer Standardization Technical Committee (SAC/TC57) administered by the National Metal and non-metal cover.

Metallic coating thickness measurement
Scanning electron microscopy
1 Scope
This standard specifies the detection of metallic cross-sectional sample local thickness by a scanning electron microscope (SEM) metal coating thickness measurement mode
Methods degrees. It is usually a destructive detection methods, uncertainty of less than 10%, or 0.1μm. This measurement method can also be used
Measuring a few millimeters thick coatings, but is recommended for such thick coatings optical microscopy (GB/T 6462) were measured.

3.1
Local thickness localthickness
Within a specified area of \u200b\u200bthe coating multiple measurements, averaging the resulting thickness value.
[GB/T 12334-2001,3.4]
Principle 4
The sample coating direction perpendicular to the horizontal cutting, grinding and polishing and carefully prepare metallographic sample, placed in a scanning electron microscope
The testing. Measured by conventional coating microscopic cross section images to obtain the coating thickness.
5 Instruments
5.1 Scanning electron microscope (SEM)
Resolution should be better than 50nm.
5.2 SEM tai micrometer scale
Used to calibrate magnification scanning electron microscope, the error value of the uncertainty should be less than 5%.
