中文摘要:
      目的 提高镁合金表面的耐蚀耐磨性。 方法 采用冷喷涂与化学气相沉积(CVD)相结合的方法在镁合金表面制备出 Cu/ W 复合涂层,并对复合涂层的结构、成分、组织形貌、耐磨性、耐蚀性、结合力进行分析。 结果 镁合金基体沉积 Cu/ W 复合涂层后,表面硬度提高了 687. 1HV,磨损率从 0. 032% 降到 0. 020% ,腐蚀电位正移了 1. 3 V,临界载荷相比直接化学气相沉积 W 涂层提高了 120. 5 N。 结论Cu/ W 复合涂层显著提高了镁基体的耐磨、耐蚀性,涂层与基体结合力较高。
英文摘要:
      Objective To improve the corrosion properties and wear resistance of magnesium alloy surface. Methods Cu/ W composite coatings were prepared successfully on magnesium alloy surface by cold spray and chemical vapor deposition (CVD). The microstructure, chemical components, morphology, wear resistance, corrosion properties of composite coatings and the binding force of composite coatings were studied. Results The surface hardness of Cu/ W composite coatings increased by 687. 1 HV compared to magnesium alloy matrix, the wear rate fell to 0. 020% from 0. 032% , the corrosion potential increased by 1. 3 V and the critical load of composite coatings improved by 120. 5 N compared to W layer directly prepared by CVD. Conclusion Preparation of Cu/ W composite coatings significantly increased wear resistance, corrosion properties and greatly improved the coating adhesion.
