电泳共沉积法制备金刚石/Al2O3/玻璃复合涂层的工艺
Preparation of Diamond/Al2O3/Glass Composite Coating by Electrophoretic Co-Deposition Method
摘要
Abstract
Diamond/A12O3/glass composite coating was prepared by electrophoretic co-deposition method on 304 stainless steel substrate,and curing of the coating on the substrate was realized through sintering method.The influence of suspension compositions,deposition voltage,deposition time and mass fraction of Al3+on the coating properties during the electrophoretic co-deposition process was investigated.Microstructure character-ization and mechanical property testing of the prepared coating were carried out,and polishing discs were pre-pared using this process for polishing sapphire substrate.The results showed that smooth and uniform dia-mond/Al2O3/glass composite coating was obtained when the deposition voltage was 50 V,the deposition time was 6 min and Al3+with mass fraction of 0.10％was added.The composite coating had a dense and uniform surface with a hardness of 521 HV after being sintered at 450 ℃ for 3 h,it also exhibited excellent abrasion re-sistance and bond strength with the substrate.The surface roughness of sapphire substrate was reduced by 90.2％after polishing using the prepared polishing discs.关键词
