Measuring thin film coating thickness is very important as it ensures the protective performance and quality of the coating. If the film coating thickness is insufficient, the coating surface is susceptible to corrosion, oxidation, etc., which can lead to substrate failure. However, if the film coating thickness is too thick, it will increase the coating cost and may cause problems such as cracking or peeling. Therefore, measuring thin-film coating thickness can help ensure that the protective properties of the coating meet design specifications and strike a balance between protection and cost. In addition, if the film coating thickness is measured during construction, construction quality problems can be found in time and adjustments can be made to ensure the quality and stability of the coating.
Coating Thickness Gauges can be used to measure the thickness of thin film coatings, such as optical films, electroplating films, chemical evaporation films, physical evaporation films, ion plating films, etc., as well as other thin film layer thickness measurements.
The operation steps are as follows:
Preparations: Check the battery power of the coating Thickness Gauge and whether the instrument is normal.
Calibration: The coating Thickness Gauge is calibrated using a standard reference block. Calibration should be performed before use to ensure the accuracy of the measurement results.
Measurement: Put the coating Thickness Gauge close to the surface of the object to be measured, and press the button to measure. When measuring, place the probe of the coating Thickness Gauge on the surface of the measured object so that it is perpendicular to the surface to ensure that the probe covers the largest area of the measured coating.
Repeated measurements: To ensure the accuracy of the results, it is recommended to take multiple measurements and calculate the average value.
Record measurement results: record the measurement results in the measurement record sheet for subsequent use and analysis.
When measuring the thickness of thin film coatings, NBCHAO reminds you to use a coating Thickness Gauge with a small probe size as much as possible, and choose different probes according to the different shapes and curvatures of the surface of the measured object. In addition, vibration and movement of the coating Thickness Gauge should also be avoided during the measurement process to ensure the accuracy of the measurement results.
