Material for enhancing surface toughness of hard and brittle material and preparation method thereof
The invention relates to the technical field of hard and brittle material processing, in particular to a material for enhancing the surface toughness of a hard and brittle material and a preparation method thereof. The method comprises the following steps: (1) adding calcium stearate micro powder and nano graphite oxide powder into an ethanol water solution, and carrying out ultrasonic dispersion to obtain a suspension; and (2) the suspension liquid obtained in the step (1) is brushed to the surface of a to-be-machined hard and brittle material workpiece, and a self-repairing layer is formed on the surface of the workpiece after the ethanol water solution in the suspension liquid volatilizes. And (3) spraying an acrylate solution on the surface of the workpiece in the step (2), and then heating and curing the workpiece to form an acrylate film layer on the surface of the workpiece. The suspension prepared from the calcium stearate micro powder and the nano graphite oxide powder is used for preparing a self-repairing layer on the surface of the hard and brittle material workpiece, and the self-repairing layer can automatically repair the problem of micro cracks generated by grinding when the surface of the hard and brittle material workpiece is ground, so that the problem of breakage is reduced.
本发明涉及硬脆材料加工技术领域，尤其涉及一种增强硬脆材料表面韧性的材料及其制备方法。所述方法包括如下步骤：(1)将硬脂酸钙微粉和纳米氧化石墨粉加入乙醇水溶液中进行超声分散，得悬浮液。(2)将步骤(1)得到的悬浮液涂刷到待加工的硬脆材料工件表面，待悬浮液中乙醇水溶液挥发后在工件表面形成自修复层。(3)在步骤(2)工件表面喷洒将丙烯酸酯溶液，然后将工件加热固化处理，使工件表面形成丙烯酸酯膜层，即得。本发明以硬脂酸钙微粉和纳米氧化石墨粉制备的悬浮液在硬脆材料工件表面制备了一层自修复层，其可以在对硬脆材料工件表面磨削加工时起到自动修复磨削产生的微裂纹的问题，从而减少崩碎问题的发生。
