Problems solved by technology

At present, my country does not have the independent intellectual property rights of the above-mentioned technologies. In addition, there is no commercialized micro-nano indentation / scratch testing instrument in China, and the instruments used rely on foreign imports. A test instrument integrating scratch test, scratch test and in-situ observation is imminent
