Abstract

In order to obtain the composite coatings of abrasion resistance and anti-corrosion, experiments of Ni-P-Al2O3-SiO2 chemical composite plating were carried out by electroless composite plating technology, and then the added amount of composite particles influenced coatings performance were investigated. After experiments, the metallographic structure, the micro-hardness, bonding strength, thickness and anti-corrosion of composite coatings were characterized by using a XJZ-6A type metalloscope and a HVS1000 type micro-hardometer, respectively. The results show that the composite coatings have bright surface appearance and the properties of bath are stable. Besides having a higher hardness, a higher thickness and a lower porosity, composite coatings combine well with the matrix and the abrasion resistance is better when the amount of Al2O3-SiO2 composite particles were added correctly. These composite particles should be treated by ultrasonic vibration firstly.
