Effect of dispersion method on microstructure and properties of Ni-P–Al2O3 (sol)-PTFE composite coating
Abstract
In order to alleviate the agglomeration of nanoparticles in the plating solution, the dispersion effect of binary nanoparticles in Ni–P–Al2O3–PTFE composite coating was studied by physical and chemical dispersion methods. The effects of different dispersion methods on the microstructure, hardness and friction coefficient of the composite coating were discussed. Through the performance evaluation of the composite coating, it is found that the effect of using appropriate dispersant and ultrasonic dispersion process is good, which can make the nanoparticles fully dispersed in the solution and evenly distributed in the coating, the composite amount of nanoparticles in the deposition layer is also high. The results show that it has a good effect on improving the wear-resisting and antifriction properties of the composite coatings.
