Our company's coating software has a base material correction function. As long as the unplated base material is tested and used as a standard data to participate in the calibration of the working curve, the interference of base material changes can be reduced.
Yes, if the binary alloy and the ternary alloy do not contain elements in the substrate or other coatings, their thickness and content can be tested. If it is contained, its thickness value can only be obtained when its percentage content is stable.
Preventing damage to an instrument preserves its performance and accuracy. Here are some suggestions:
Avoid exposing the instrument to severe vibrations, bumps or excessive stress.
When not in use, store the instrument in a safe location away from objects or conditions that could cause damage.
Follow the correct use method and operation guide to avoid damage caused by wrong operation.
Yes, regular calibration is essential to ensure accurate measurements. Calibration corrects for instrument bias and compares to known standards. Here are related suggestions:
Calibrate the instrument at regular intervals according to the manufacturer's recommendations and instructions for use.
Calibration can be performed by the manufacturer, or you can send the instrument to an accredited calibration laboratory for calibration.
Record calibration dates and results for traceability and reference
If the analyzer won't start up or connect to a computer or other device, you can try the following steps:
Check power supply: Make sure the analyzer is properly connected to a power source, and check that the battery is fully charged (if using battery power).
Connection check: Check the connection between the instrument and the computer or other equipment to ensure that the plug and socket are well connected.
Drivers and software: Make sure you have the correct drivers and measurement software installed and follow the manufacturer's instructions.
Reboot: Try restarting the analyzer and associated equipment, sometimes this can resolve temporary connection issues.
Contact Support: If the problem persists, contact the manufacturer of the thickness analyzer or the technical support team for further assistance and support.
Here are some suggestions for maintaining your coating thickness analyzer:
Storage conditions: Thickness measuring instruments should be stored in a dry and clean environment, avoiding excessively high or low temperature and humidity, to ensure accurate measurement results. Pay attention to waterproof and electricity, and avoid collisions.
Cleaning: When dirty, wipe with a clean soft cloth, avoid using solvents containing acidic or corrosive ingredients.
Periodic Calibration: Periodically calibrate the thickness analyzer according to the manufacturer's recommendations. Calibration ensures that the instrument provides accurate measurements.
Prevent Damage: Avoid exposing the thickness analyzer to severe vibration, bumps or excessive pressure to prevent damage to the instrument or accessories.
Most coating thickness analyzer offer unit switching. You can find the unit option in the instrument's settings menu and select the appropriate unit, such as millimeters (mm), micrometers (μm), nanometers (nm), etc.
Measurement results can be affected by:
Surface preparation: The coating thickness analyzer has strict requirements on surface preparation to ensure that the surface is smooth, free of impurities, and free of corrosion. Measurements may be inaccurate if the surface is not adequately prepared.
Calibration: Make sure the coating analyzer is properly calibrated to provide accurate test result. Regular calibration is critical.
Effect of coating structure: For multi-layer coating structure, it is necessary to ensure that the coating structure is consistent with the coating method, which means the order of the coating elements corresponds to the method, otherwise the accuracy of the test results will be affected.
Measurement Technique: When using coating analyzer, make sure to properly select the proper measuring technique and settings to accommodate different types of coatings.
Measurement location: The area of the coating thickness measurement location is limited, and different locations will be affected by the coating technology, and there will be unevenness. It is recommended to take the average value of the thickness of different locations in the actual test.
Thickness measurement range: XRF test coating thickness, for different structures, there are different theoretical test thicknesses, If the actual coating sample thickness exceeds the theoretical test thickness, the test results have no reference value.
Instrument failure: If the above steps have been carried out correctly, but there is still a deviation, there may be a problem with the coating analyzer itself. In such cases, it may be necessary to inspect the instrument and repair or replace it.
It is not generated immediately, and there is about a delay of femtosecond (ps) level. Because according to the mechanism generated by Raman, after the incident photon interacts with the molecule, the molecule is excited and forms a short-lived virtual state, which is unstable. The photon is quickly re-emitted.
1. The Raman spectrum is a molecular spectrum, and metals are atomic structures, so metals do not have a Raman spectrum.
2. There is no molecular vibration in metals, of course there is no Raman spectrum.
3. Many substances composed of atoms have Raman signals, such as the 520 wave number line of silicon. Raman measures the vibration energy level, phonon energy, reflects the size of the quantized energy of the lattice vibration. Plasma has a strong absorption of light (which is also related to the high reflective properties of metals), so that the laser cannot interact with the internal atoms, so it is difficult to see Raman lines.
