Method for preparing ceramic coating on metal matrix
The invention relates to the technical field of coating materials, in particular to a method for preparing a ceramic coating on a metal matrix, which comprises the following steps of: preparing the ceramic coating on the metal matrix by adopting a sol-gel method, putting the metal matrix into silicon oxide sol, silicon oxide-titanium oxide composite sol or silicon oxide hybrid sol, soaking for 1-1.5 minutes, and drying to obtain the ceramic coating on the metal matrix. And vertically pulling out from the sol at a constant speed of 0.8-1mm/s, airing at room temperature until the surface is dry, drying in a drying oven at the temperature of 100-110 DEG C for 20-30 minutes, performing heat treatment, and then performing air cooling, thereby obtaining the ceramic coating on the metal substrate. Wherein when the sol is silicon oxide sol or silicon oxide-titanium oxide composite sol, the heat treatment is performed for 1-2 hours at the temperature of 200-300 DEG C; and when the sol is the silicon oxide hybrid sol, the heat treatment is carried out at 100-150 DEG C for 1-2 hours. The ceramic coating can enhance the hardness and wear resistance of the metal matrix.
本发明涉及涂层材料技术领域，尤其涉及一种在金属基体上制备陶瓷涂层的方法，该方法采用溶胶‑凝胶法在金属基体上制备陶瓷涂层，将金属基体放入氧化硅溶胶、氧化硅‑氧化钛复合溶胶或氧化硅杂化溶胶中，浸泡1～1.5min后，从溶胶中以0.8～1mm/s的速度匀速垂直提拉出来，室温晾晒至表面干燥后，放入100～110℃的烘箱中烘干20～30min，再进行热处理，然后空冷，即在所述金属基体上制得所述陶瓷涂层；其中，当所述溶胶为氧化硅溶胶或氧化硅‑氧化钛复合溶胶时，所述热处理为在200～300℃下热处理1～2h；当所述溶胶为氧化硅杂化溶胶时，所述热处理为在100～150℃下热处理1～2h。该陶瓷涂层能够增强金属基体的硬度和耐磨性。
