Before hardness detection, it is usually necessary to grind off the attached dirt or paint on the surface to improve the detection accuracy. When performing flaw detection, it is usually necessary to apply a coupling agent to reduce the energy loss of the flaw detection signal during propagation to improve the detection accuracy.
