Teflon spraying strengthening on the surface of metal samples

       Metal thermal spraying technology can not only be applied to the surface of damaged workpieces, but also can be used to strengthen the surface of new workpieces, such as small shafts, bushings, plungers and other workpieces. Before use, a layer of metal coating can be prepared on the surface. , in order to achieve the effect of enhancing the performance of the surface. This is one of the reasons why the thermal spray process continues to grow in the field of additive manufacturing.



While repairing damaged workpieces, wococarbide.com is also constantly researching and preparing new functional coatings, and actively seeking cooperation to prepare higher performance protective coatings. During the test process of wococarbide.com, one of the processes is to use the supersonic spraying process to spray the Teflon coating on the surface of the sample. Properties such as pressure and spraying speed are strictly controlled to ensure coating quality. The sample selected this time is about 0.4 square meters, and the supersonic spraying process is used to spray Teflon coating on the surface. The thickness of the finished coating is required to be > 0.15 mm, and the hardness is > HV900. At the same time, it is necessary to ensure that the coating is well bonded and free of blisters and pores. , peeling, etc.



The significance of the thermal spraying process is that it can not only repair the surface performance of damaged workpieces, but also add new protective clothing to new workpieces. Therefore, as a kind of metal surface strengthening, thermal spraying technology will be more and more widely used.
