Insulating anti-corrosion composite ceramic coating as well as preparation method and application thereof
The invention discloses an insulating anti-corrosion composite ceramic coating and a preparation method and application thereof, and belongs to the technical field of metal surface corrosion prevention, the insulating anti-corrosion composite ceramic coating comprises Al2O3, ZrO2 and SiO2, ZrO2 accounts for 1/3-1/10 of the mass of Al2O3, and SiO2 accounts for 2-5% of the sum of the mass of Al2O3 and ZrO2. The preparation method comprises the following steps: preparing uniformly mixed composite ceramic powder, pretreating the surface of a base material, performing thermal spraying on the base material by taking the mixed powder as a spraying raw material, and performing laser remelting post-treatment on the coating, thereby obtaining the composite ceramic coating with high density, high bonding strength, better mechanical property, corrosion resistance and insulating property. The problems that an aluminum oxide coating is brittle, cracks are prone to being generated, the bonding strength with a metal base material is not enough, the coating density is not enough and the process is tedious due to the fact that an alloy transition layer is needed are solved, and the method has important application value for meeting the anti-corrosion requirement of offshore wind power equipment.
本发明公开了一种绝缘防腐复合陶瓷涂层及其制备方法与应用，属于金属表面防腐技术领域，其组分包括：Al2O3、ZrO2、SiO2，ZrO2占Al2O3质量的1/3～1/10，SiO2占Al2O3和ZrO2质量之和的2％～5％。通过制备混合均匀的复合陶瓷粉体、基材表面预处理、混合粉体为喷涂原料对基材进行热喷涂、涂层进行激光重熔后处理得到具有高致密度、高结合强度、更好的力学性能、耐腐蚀性能和绝缘性能的复合陶瓷涂层，解决了氧化铝涂层脆性、易产生裂纹、与金属基材结合强度不够、涂层致密度不够的性能不足的问题及需要合金过渡层导致的工艺繁琐的问题，对于满足海上风电设备的防腐蚀需求具有重要的应用价值。
