Description

一种旋耕机用高强耐磨旋耕刀
技术领域
本发明涉及金属表面处理工艺技术领域，具体涉及一种旋耕机用高强耐磨旋耕刀。
背景技术
旋耕机是与拖拉机配套完成耕、耙作业的耕耘机械，因其具有碎土能力强、耕后地表平坦等特点，而得到了广泛的应用；同时能够切碎埋在地表以下的根茬，便于播种机作业，为后期播种提供良好种床。目前旋耕机多用于开垦灌木地、沼泽地和草荒地，干湿条件下均可操作，适用范围广。旋耕刀为旋耕机重要组件，在工作时，通过动力输出轴使得旋耕刀片插入土层中所需深度，然后进行旋转翻耕，由于旋耕机的高强度和高适性操作，旋耕刀常常磨损消耗严重，容易锈蚀，使用周期较短，增大了成本支出。因此，为了适应旋耕机的高强度和高适性操作，需要对旋耕刀进行强化处理，提高其耐磨蚀和强韧性。
发明内容
针对上述存在的问题，本发明提出了一种旋耕机用高强耐磨旋耕刀，具有优异的耐磨防腐性，硬度可达520HV以上，磨损量小于15mg/h，疲劳强度375MPa(107循环周次)，抗拉强度大于528.6MPa，屈服强度大于431MPa。
为了实现上述的目的，本发明采用以下的技术方案：
一种旋耕机用高强耐磨旋耕刀，包括合金刀体、离子渗镀层和防腐涂层，所述合金刀体为B-Zr-Y-Nb掺杂铸铁件，所述离子渗镀层为采用双层辉光技术渗镀AlN/TiN/FeS，所述防腐层为改性树脂涂层。
优选的，所述合金刀体由以下百分含量组分制成：C 3.15-3.28％、Si 1.36-1.57％、Mn 1.84-1.96％、B 0.58-0.9％、Zr 1.3-2.6％、Y 0.05-0.23％、Nb 0.4-0.75％、余量为Fe和不可避免的杂质。
优选的，所述离子渗镀层厚度为0.12-0.14mm，由合金刀体向防腐层依次为TiN层、FeS层和AlN层。
优选的，所述离子渗镀层中各镀层厚度占总厚度比为TiN层20-40％、FeS层10-15％、剩余为AlN层。
优选的，所述改性树脂涂层厚度为0.15-0.2mm。
优选的，所述改性树脂涂层具体为纳米中孔氧化铝复合改性环氧丙烯酸树脂。
优选的，所述纳米中孔氧化铝添加量为改性树脂涂层总量的8-16％。
由于采用上述的技术方案，本发明的有益效果是：本发明采用合理的元素配比对铸铁件本体进行掺杂改性，提高了合金刀体的综合机械性能，配合合金刀体外层的离子渗镀层，耐磨性提高了3倍以上，且以TiN层与合金刀体相触、AlN层与防腐层相触，不仅有益于提高内层本体的掺杂性，提高耐磨强度，同时配合外层纳米中孔氧化铝有利于增强涂层粘接性能，提高了粘结力。本发明制得的产品具有优异的耐磨防腐性，硬度可达520HV以上，磨损量小于15mg/h，疲劳强度375MPa(107循环周次)，抗拉强度大于528.6MPa，屈服强度大于431MPa。
