Dredger reamer tooth with high wear resistance
The invention relates to the technical field of reamer teeth for dredging, and particularly discloses a high-wear-resistance dredger reamer tooth which comprises a reamer tooth body and a wear-resistant layer, and the wear-resistant layer is formed by mixing hard alloy particles and a base material; the wear-resistant layer is attached to the surface of the reamer tooth body through heating; wherein the heating temperature ranges from 950 DEG C to 980 DEG C; according to the invention, on one hand, the hard alloy particles are directly added into the wear-resistant layer, so that the WC content in the wear-resistant layer can be effectively improved, and the hardness of the wear-resistant layer can be effectively improved; and on the other hand, the wear-resisting layer is attached to the surface of the reamer tooth body through heating, the limitation of a traditional laser cladding and flame welding machining technology is broken through, the wear-resisting layer can be effectively prevented from cracking, the thickness of the wear-resisting layer is increased, the binding force between the reamer tooth body and the wear-resisting layer can be improved, and the wear-resisting layer is prevented from falling off.
本发明涉及用于挖泥的绞刀齿的技术领域，具体而言，公开了一种高耐磨性能挖泥船绞刀齿包括绞刀齿本体和耐磨层，耐磨层由硬质合金颗粒和基体材料混合而成；耐磨层通过加热附着于绞刀齿本体的表面上；其中，加热温度在950‑980℃；在本发明中，一方面，在耐磨层内直接加入有硬质合金颗粒，能够有效提高耐磨层内的WC含量，能够有效提高耐磨层的硬度；另一方面，通过加热升温来将耐磨层附着于绞刀齿本体的表面上，突破了传统激光熔覆和火焰焊接的加工工艺的限制，能够有效防止耐磨层开裂，并提升耐磨层的厚度，还能够提升绞刀齿本体和耐磨层之间的结合力，防止耐磨层脱落。
