| 摘 要： | 采用高能球磨及化学镀镍技术来改善B4C颗粒的粒度、分布及其表面状态，制备了热喷涂用Ni60／（Ni／B4C）团聚粉和Ni60-B4C（包覆Ni）复合粉，采用亚音速热喷涂技术制备了其耐磨涂层，在自制的销盘式磨损试验机上进行涂层的磨粒磨损实验，结果表明：Ni60-B4C（包覆Ni）涂层与Ni60／（Ni／B4C）涂层相比更耐磨。

| Abstract: | Ni60/(Ni/B_4C) reunion powder and Ni60-B_4C(wrapped Ni)composite powder were made for thermal spraying. Using high energy ball milling and electroless nickel technologies, we reformed B_4C particles grain size, distribution and surface state to improve theirs wear resistance, and prepared wear-resistance coatings with subsonic speed flame spraying technology. We carried out the grit wearing experiment of the coating in the type of pin-dish-wearing machine made by ourselves. The results show that the wear-resistance of the coating of Ni60-B_4C(wrapped Ni) is better than that of Ni60/(Ni/B_4C) coating. |
