| 摘 要： | 在45钢基体表面等离子弧喷涂制备了掺杂不同含量CeO2纳米ZrO2涂层，运用XRD，SEM对涂层的组织结构进行了分析，测试了涂层的结合强度和显微硬度，考察了涂层与铝青铜对磨时的摩擦磨损性能．结果表明，CeO2增加了ZrO2涂层的致密性、结合强度和显微硬度．纳米ZrO2涂层中加入CeO2后，增加了ZrO2涂层／铝青铜摩擦副的摩擦系数，增强了纳米ZrO2涂层，耐磨能力．涂层与铝青铜对磨时，随着CeO2含量的增加，ZrO2涂层粘着磨损形式增强，而涂层脆性断裂脱落的趋势减轻．

| Abstract: | Nano zirconia coatings doped different CeO2 content on 45 steel matrix were successfully fabricated by atmospheric plasma spraying.The microstructure of coatings was characterized by XRD and SEM.The adhesive strength and micro-hardness were tested, and the friction and wear properties of zirconia coatings were investigated.The results indicate the density, adhesive strength and micro-hardness of coatings are inproved with doped cerium oxide.With the cerium oxide increasing, the friction coefficients and wear resistance of zirconia coatings against aluminium bronze increase.The adhesive wear of zirconia coatings increases, while the brittle fracture of zirconia coatings decrease. |
