GK PDC for rock cutting picks manufacturers tell you that at present, the use of composite boards is becoming more and more extensive, and the corresponding detection methods must also meet the requirements. The manufacturer of GK PDC for rock cutting picks tells you that with the research on the inspection method of the composite plate, the requirements for its various properties are getting higher and higher in the actual use process, and its development has the following trends. Then, let's learn about diamond composite Film performance and testing!

1. Wear resistance. The manufacturer of GK PDC for rock cutting picks tells you that the wear resistance test is carried out from the microstructure of the composite sheet, which can not only accurately measure the wear resistance of the composite plate, but also find out the internal reasons that affect the wear resistance and improve the wear resistance.
2. Thermal stability. At present, the study of thermal stability of composite panels inevitably involves the concept of thermal damage, which can understand the shape, degree and characteristics of damage, which refers to the damage of PDC caused by heat. The advantage of observing the composite sheet before and after heat treatment is that it can analyze the cause of damage to the composite sheet and find a solution. This method can be used to judge the thermal stability of the composite sheet and improve the thermal stability of the composite sheet accordingly.
3. Impact performance. The manufacturer of GK PDC for rock cutting picks tells you that the composite sheet is damaged by impact in actual use, which is generally divided into two types: multiple impact damage and sudden large impact damage. Therefore, when testing the impact performance of the composite sheet, it is necessary to simultaneously test the maximum impact resistance and impact toughness. Due to the characteristics of the composite plate itself, the maximum impact energy is largely determined, that is, the fatigue test, but the obvious disadvantage of the fatigue test is that it is easy to produce errors. Therefore, the requirements for the required equipment and instruments are very high, so generally only the impact toughness of the composite board is tested, and the impact resistance testing method will be developed in the direction of large impact force and high precision.
4. Residual stress check. The manufacturer of GK PDC for rock cutting picks tells you that the residual stress inside the composite sheet is characterized by neutron diffraction method. The residual stress inside the diamond composite sheet affects the thermal stability and impact resistance of the composite sheet, and is mainly based on thermal residual stress. Specific values ​​can be obtained.
It has been applied to a certain extent in the country
1. Fundamentals. The steel ball is allowed to fall freely at a certain height. During the test, the impact ball is made to collide with the edge part of the PDC in turn (one impact energy is generally 0.2 J), and the potential energy of the steel ball is converted into kinetic energy (impact energy), so that the energy and Test specimen collision. The impact energy obtained when visible cracks or breakage occur on the surface of the sample is used as a quantitative index for measuring impact resistance, and is expressed as impact energy.
2. Disadvantages. It is completely feasible in principle, and the test error can also meet the requirements.
