Microstructure of coating prepared by particle jet electrodeposition

Abstract Now,machinery and equipment, vehicle engineering, oilfield equipment corrosion and a lot of useless scrap parts phenomenon is people have paid attention to the problem, and in recent years, lots of experiments and reported that the equipment of protective coating and is a feasible and effective method of scrap parts repair, save cost, effectively turning waste into treasure。

This design through the method of particle jet electrodeposition coating was prepared, by method of control variables that control two parameters unchanged, transform a parameter to get the coating microstructure。 And by scanning electron microscopy coatings was observed, comparative analysis of relationship between organizational structure and process。 Observation on organizational structure reflects the effects of process parameters on the performance of the organization so as to improve the process parameters。

In this experiment, to delay the passivation of the tool or scrap, scrap parts repair, parts corrosion protection has a very important significance。 This graduate design thesis is under the guidance of a teacher after a lot of experiments and the experimental results under the scanning electron microscope to coating do the most rigorous data analysis, obtained the experimental results。
