The testing of cemented carbide is an important process to ensure the performance of cemented carbide material, including the testing of cemented carbide material properties and the testing of tungsten carbide products’ specifications and dimensions.
Last week when we test 100% qualified products and ship them to our customer, feedback was received that the dimensions are out of tolerance during their inspection process, but after we remind them and they find that the materials are qualified. The situation happens,Why is this? Because the inspection of cemented carbide is prone to deviations, in metal material inspection, accuracy control is the key to ensuring the accuracy of test results.
The accuracy of metal material testing is affected by many factors, including operator skills, accuracy of testing instruments, stability of the testing environment, etc. In order to control errors and improve test accuracy, the following aspects need to be paid attention to:
1. Instruments calibration: To choose appropriate instruments for different measurements. Regular calibration of test instruments is a key step to ensure accurate test results. According to the instrument instruction, regular calibration and verification are performed to ensure the accuracy and stability of the test instrument.
2. Sample preparation: Before conducting testing, ensure that the surface of the sample is smooth and free of defects. Improper specimen preparation can affect the accuracy of test results. The surface of the specimen should be ensured to be clean and oxides, grease, etc. should be removed to avoid affecting the testing process.
3. Test operation: When conducting tests, the operator should be familiar with the use of test instruments and perform correct operations according to test requirements. During the test, the test environment should be kept stable to avoid the influence of temperature, humidity and other factors on the test results.
1. Multiple tests: In order to improve the accuracy of test results, you can conduct multiple tests and average multiple data. Multiple tests can reduce errors caused by human errors and test instrument accuracy, and improve the reliability of test results.
In order to obtain accurate and reliable test results, we need to pay attention to the influence of these factors and take corresponding measures to reduce deviations. Only in this way can we better evaluate the hardness of materials and provide accurate data support for related engineering and scientific research.
