Description

technical field [0001] The invention relates to a copper alloy surface coating structure, device and method based on rare earth nanoparticles. Background technique [0002] Copper alloy is a very important industrial production material, which is used in many technical fields. For example it can be used for cables in power transmission. In addition, it can be used for motor manufacturing. Furthermore, it also has very important applications in vacuum devices, printed circuits, integrated circuits, etc. in the electronics industry. [0003] However, in some relatively high-end or confidential occasions, due to the inherent properties of the surface of the copper alloy, it is easy to leave fingerprints or traces after human touch, which will cause problems for the use of some occasions . [0004] In order to solve this technical problem, attempts have been made in the prior art to coat the surface of the copper alloy with nanoparticles in order to improve the surface prope...

AI Technical Summary

Problems solved by technology

However, on the one hand, there is no suitable nanoparticle material in the prior art that can better solve the above problems; on the other hand, for the spraying action of large quantities of copper alloy structures, especially for continuous operations In general, in order to save space distance and improve work efficiency, multi-layer transmission platforms are placed at different heights, and each layer of the platform can be used as the transmission function of the copper alloy plate, and the copper alloy plate of this multi-layer platform needs to pass through Spray structure to complete the spray action

However, in the actual work process, it is found that the adjustment of the placement position of the sprayed structure of the copper alloy plate on the multi-layer platform is relatively independent, that is, the spraying distance of the sprayed structure on each layer of the platform is independently adjusted, and if each layer of the platform When the spraying distance of the spraying structure is inconsistent, it is easy to cause the inhomogeneity of the layer thickness of the product spraying, which will lead to the decline of product quality

In addition, if the height position of the spraying structure on the first-floor platform is adjusted separately, the work will be complicated and the entire workload will be increased.
