中文摘要:
      采用高频感应熔覆的方法,制备了两种熔覆加热时间不同的 Ni45 B 合金涂层,并分析了涂层的显微组织结构和主要成分。 结果表明:延长加热时间,可以增强涂层元素与基体元素的相互扩散,使过渡层宽度增加,还可以使涂层中各种元素的分布更加均匀;加热时间短的涂层中分布着大量白斑,这是铬元素在涂层中发生聚集而形成的,随着加热时间的延长,铬元素均匀地分散到涂层中,白斑消失;加热时间长的涂层,由于杂质和气泡有充足的时间上浮,因此缺陷明显较少。
英文摘要:
      Two kinds of Ni45 B alloy coatings were prepared by high frequency induction cladding in case of different cladding heating time. The microstructure and main ingredient of the coating were observed. The results show that when the heating time increases, mutual diffusion of elements will be increased, so that the buffer layer width increases and the distribution of the various elements in the coating is more uniform. There are a lot of white spots in the coating when the heating time is short , this is due to the aggregation of the chromium elements in the coating. Along with the extension of the heating time, the chromium elements disperse in the coating uniformly and the white spots disappear. The coating with long heating time has a long time in melt state, which make it have enough time to separate the impurity and bubble, so the defects in the coating reduces significantly.
