X-ray fluorescence thickness gauge is a coating thickness measuring instrument based on X-ray fluorescence principle. The following steps are used to test the coating thickness with an X-ray fluorescence thickness gauge:
Preparatory work:
Take out the X-ray fluorescence thickness gauge, make sure that the instrument is fully charged or connected to the power supply, and check whether the instrument is in good condition.
Clean the surface of the sample to be tested to ensure that the surface is clean and smooth without impurities, dust and oil stains.
Set measurement parameters:
Turn on the power switch of the X-ray fluorescence thickness gauge and enter the measurement mode.
According to the type and thickness range of the coating to be measured, appropriate measurement parameters, such as elemental spectrum, voltage and current, are selected.
Take measurements:
Place the measuring probe of X-ray fluorescence thickness gauge near the surface of the coating to be measured, and ensure that the probe is in close contact with the surface of the coating without obvious gap.
Press the measurement button, the instrument will automatically measure the X-ray fluorescence and record the thickness data of the coating.
Read results:
The display screen of X-ray fluorescence thickness gauge will display the measurement results, including coating thickness, measurement unit, measurement error and other information. Records and data processing can be carried out as required.
End measurement:
After the measurement is completed, turn off the power switch of the X-ray fluorescence thickness gauge, remove the measuring probe, tidy up the instrument and accessories, and store them in the designated location.
When testing the coating thickness with X-ray fluorescence thickness gauge, the following points should be noted:
Cleaning the sample surface: In order to ensure the accuracy of measurement, the sample surface must be clean, flat and free of impurities, dust or oil stains.
Selection of appropriate measurement parameters: according to the type and thickness range of the coating to be measured, select appropriate measurement parameters, such as elemental spectral lines, voltage and current.
Maintain stable measurement conditions: During the measurement, the measuring probe should keep stable contact with the coating surface to avoid inaccurate measurement results due to the probe moving or uneven stress.
Regular calibration and maintenance of instruments: In order to ensure the accuracy and stability of instruments, it is necessary to conduct regular calibration and maintenance of instruments.
In a word, when using X-ray fluorescence thickness gauge to measure the coating thickness, it is necessary to choose the appropriate measurement method and parameters according to the specific measurement requirements and sample characteristics. At the same time, pay attention to keep the instrument clean and stable in working condition, so as to obtain accurate measurement results.
