Abstract:

The phenomena of abrasion and corrosion often appear during the working process of the spare parts of agricultural equipments, which lead the spare parts to lose efficacy earlier. According to the research at home and abroad, the magnetic field can enhance the dispersibility and coverage of the electroplating solution as well as have strong effects on the microstructure and morphology of the electroplating plating. The static magnetic field vertical to the depositing orientation of the cation was introduced in this experiment to improve the plating properties of spare parts of agricultural equipments .By the light microscope, the morphology of the Ni-Co alloy was observed, and the properties of the plating was tested by the microhardness tester. The results showed that the Ni-Co alloy becomes smooth and fine with the depositing state of the cation changed by the magnetic field, the hardness of the plating prepared with the static magnetic field was raised by 38 HV as that without the magnetic field applied. This study provided a simple and practical method for improving the plating properties of spare parts of agricultural equipments, and offers a reference for further study.
