Mechanical Milling Prepared Ultrafine Al₂O₃ Particles Utilized in Brush Plating Ni-P-Al₂O₃ Coatings and Influence of Heat Treatment to the Performance of the Coatings

Abstract:

In this paper, ultrafine Al₂O₃ particles were prepared by mechanical milling, and Ni-P-Al₂O₃composite coatings were plated on Q235 steel substrates by brush-plating, which plating solutions were containing different concentrations Al₂O₃ particles. The morphology, phase and particle size distribution of the as-prepared Al₂O₃ particles, and the properties of the coatings after heat treatment were investigated. The results show that, the morphology of the as-prepared Al₂O₃ particles were spherical and almost size under 200nm, the coatings were uniformly thickness and the Al₂O₃particles were uniformly dispersed in the coatings. Heat treatment could improve the performances of the brush-plating Ni-P-Al₂O₃ layers. After 1 hour heat treatment in 400°C, the layer which phosphoric content about 2.3wt% had high rigidity, good abrasion-resistance and adhesion strength, and the layer which phosphoric content about 10.1wt% has good erosion-resistance after 1h heat treatment in 600°C.
