| 中文摘要: |
| 分别用高温涂料保护熔覆和感应熔覆两种方法在45钢表面制备了Ni60自熔性合金涂层,并用金相显微镜、XRD、SEM和显微硬度计等分析仪器对这2种熔覆层的组织结构和性能进行了分析比较。试验结果表明:在高温涂料保护熔覆过程中,高温保护涂料能够对基体和熔覆层起到很好的防氧化保护作用,熔覆层表面平整、组织致密、与基体之间结合牢固。通过对高温涂料保护熔覆后的试样进行正火处理,可以改善基体的组织和性能,消除因高温熔覆对基体材料带来的不利影响。与感应熔覆相比,高温涂料保护熔覆层质量好,熔覆设备投资少,可以对各种形状的零件表面进行熔覆处理,是一种高效节能的熔覆处理新技术。 |
| 英文摘要: |
| The clad layers of Ni60 self-fluxing alloy were prepared on 45 steel by high-temperature protective coating cladding and induction melting respectively. The microstructures, compositions and microhardness of the cladding layers were analyzed and compared by OPM,SEM,XRD and microhardness testing. The experimental results show that the high-temperature protective coating cladding can prevent the Ni60 alloy powder and matrix from oxidizing and a uniform,adherent and non-dilution cladding layer can be obtained. The adverse effects of high temperature on the matrix material can be overcome by means of the normalizing treatment after the high-temperature protective coating cladding. Compared with the induction melting, the high-temperature protective coating cladding has many advantages, such as high cladding quality, low cladding cost, and various shape cladding. |
