| 摘 要： | 采用Al2O3和NiCr-Cr3C2复合粉末两种材料作为填充材料制备了曲轴表面改性用金属陶瓷喷涂药芯丝.分析了涂层显微组织,测试了涂层结合强度和耐磨性能.结果表明,采用Al2O3作为填充材料的药芯丝制备出的涂层中陶瓷相含量高,涂层和基体结合良好.涂层和基体结合强度达到21.23 MPa,抗剪强度达到31.27 MPa.涂层耐磨性好,相同摩擦磨损条件下,磨损失重仅为灰口铸铁试样的1/4.Ni3Al和石墨的加入是涂层结合强度高的主要原因.

| Abstract: | Cored-wires with Al_2O_3 and NiCr-Cr_3C_2 as filler materials for surface modification of cranshaft were produced.Microstructures,bonding strength and wear-resistance of coatings produced with these two cored-wires were tested.The results showed that,with Al_2O_3 as filler material of the cored-wire,content of ceramic phase in the coating was high,and the coating was fairly bonded to the substrate.Aahesive strength was as high as 21.23 MPa,and the shear strength of the coating was 31.27 MPa.Resistance to wear of the coating was good.With same wear conditions,the wear loss of mass was only one-fourth of that of the cast iron sample.Addition of Ni_3Al and graghite was the most important reason for high adhesive strength. |
