| 目的 通过研究镁硼硅晶膜改性技术对镍-磷复合镀层组织性能的影响，开发并提升工业应用价值较高的非晶态镍-磷镀层。方法 采用镁硼硅晶膜改性处理技术，在45#钢基材上制备Ni-P化学镀层，通过扫描电子显微镜等设备，检测处理后镀层的微观形貌、组织结构和耐磨耐蚀性能，结合镁硼硅水体活化表征，分析镁硼硅晶膜改性技术对镍-磷镀层的强化机理。结果 相比传统的Ni-P镀层，镁硼硅改性晶膜处理的Ni-P镀层表面平整，分布均匀，表面致密度明显提升，摩擦因数减小了约32%，腐蚀电位正移221 mV，腐蚀电流为原来的1/2，腐蚀质量损失速率明显较低，耐腐蚀性能更为优异。经过镁硼硅改性晶膜处理的水体分子团明显减小，活性提升，这说明经过处理后的水体易于溶解来自复合陶瓷中的硅石和硼素等物质，在Ni-P镀层形成致密的晶膜，提高镀层的综合防护性能。结论 经过镁硼硅晶膜改性处理后，Ni-P镀层表面致密度和耐磨耐蚀性能有了明显的提升，具有更为宽广的工业应用价值。 |

| The work aims to design and prepare amorphous nickel-Phosphorus coatings with high industrial application value by studying the influence of the modification technology of magnesium boron silicon crystal film on the microstructure and properties of nickel-phosphorus composite coatings. The magnesium boron silicon crystal film was prepared on the Ni-P chemical coating. The micro-morphology and corrosion properties of the coatings were studied by scanning electron microscope and other equipment. Combined with the water activation characterization, the strengthening mechanism of the Ni-P coating by the modification technology of magnesium boron silicon crystal film was analyzed. Compared with the traditional Ni-P coating, the Ni-P coating treated by the modification technology of magnesium boron silicon crystal film had a great surface density and uniform distribution. After treatment, the corrosion potential was shifted by 65.6 mV, the corrosion current was half of the original, and the corrosion weight loss rate was significantly lower. In addition, the size of Water cluster treated by modification technology of magnesium boron silicon crystal film were significantly reduced and the activity was improved, which indicated that the treated water was easy to dissolve materials such as silica and boron from composite ceramics, forming a dense crystal film in the Ni-P coating and improving the comprehensive protection performance of the coating. After the treatment of magnesium boron silicon crystal film modification technology, the surface density and wear resistance of Ni-P coating have been improved obviously, which has broader industrial application value. |
