The destructive test means that the sample will be destroyed during the test, and the sample no longer has the original value of use after the test is completed. For example, during the test, the sample is dissolved, cut, or the lock layer is removed, and the sample is bent. Therefore, when the sample is a product or the value of the sample is high, the destructive test method is generally not used. When a product is not suitable for destructive test and data of such destructive test is needed, it is necessary to make an alternative test piece. At this time, it is necessary to take the same material as the tested product to make a test piece convenient for testing. Let it go through the same electric lock process as the tested product, and then conduct a destructive test on this substitute test piece, so as to obtain parameters for reference. When the performance of the base material does not affect the locking layer or has no impact on the test, a base material different from the original product can also be used.
Non-destructive test means that the test process does not cause any damage to the sample. After the test is completed, the state of the sample does not change. When the sample is a product or a spare part, its function will not be affected after , so it is suitable for Testing of product samples. However, the methods of non- destructive testing are often limited, and the cost of some non-destructive testing will be higher.
Therefore, in many occasions, the electroplating test still uses a destructive test method. This is because the parameters of the test can be obtained more intuitively and directly by destroying the sample. The parameters of the simulation test sometimes deviate greatly from the real process. Of course, another reason is that the electroplating manufacturing industry has always retained the agreement on production process losses, so the samples used for process tests are often included in the process losses, so that the field tests in the electroplating industry often directly use the actual product as the test sample. , even for destructive tests. From the perspective of resource conservation, it is still necessary to increase the level of simulation tests and reduce the number of destructive tests using products .
