Background
In the thermal spraying process, in order to ensure the reliability of the sprayed process parameters, before the coating spraying of the parts in different batches, the coating spraying of the parts is required to be carried out by using test pieces, and corresponding tests such as a hardness test, a tensile test, a bending test, a metallographic test and the like are carried out on the test pieces, and the parts can be sprayed only after the required coating tests are qualified. According to the requirements of different tests, the specifications of the test pieces mainly comprise rectangular thin sheets (about 100mm multiplied by 20mm multiplied by 1.5 mm) which are mainly used for bending tests, metallographic tests, hardness tests and the like, and round cakes (about phi 25mm multiplied by 10 mm) test pieces are mainly used for tensile tests, hardness tests and the like. When spraying test pieces for various tests, the test pieces are arranged on a turntable with fixed outer diameter for spraying, the outer circle (inner circle) diameter of the part to be sprayed area is consistent with the outer diameter of the turntable, the difference between the outer circle (inner circle) diameter of the part to be sprayed area and the spraying position of an actual part is large under other conditions, the spraying position of the test pieces is different from the spraying position of the part, and the spraying of the part is performed through the process parameters determined by the spraying of the test pieces, so that the spraying of the part is not very strict. Therefore, the spraying of the test piece is used to reflect a certain deviation of the spraying of the parts, and the deviation sometimes has serious quality influence on high-end industrial parts (such as aviation and aerospace industries) with increasingly improved processing precision.
How can the spray position of the test strip be made to coincide with the spray position of the part so that its spray parameters can be used as a reference for the spraying of the part? And selecting a solid part as a test part to perform test spraying, and starting to spray the formal part after the test is qualified. Although this method is feasible, the cost is too high, and it is necessary to destroy, cut and sample the solid parts, and then perform various tests and tests, which are obviously not the best method for the parts made of various expensive materials (such as titanium alloy, superalloy, etc.), and the process is too complicated, which is also unfavorable for improving the efficiency in the production process.
