摘要:
针对海洋装备常用的Q235钢材料，为解决其腐蚀失效的问题，采用等离子浸没沉积(PIID)的空心阴极放电技术制备了3组类金刚石涂层(DLC)，研究了Si和Cu元素掺杂对DLC涂层结构和耐蚀性能的影响。结果表明：Si掺杂(Si-DLC)涂层为非晶结构，Cu掺杂(Cu-DLC)涂层和Si、Cu双掺杂(Si/Cu-DLC)涂层均为纳米Cu晶粒镶嵌在非晶碳基体上的复合结构。3组涂层的结合性能从高到低依次为Si-DLC(18.5 N)＞Si(Cu)-DLC(13.9 N)＞Cu-DLC(9.4 N)。Si-DLC涂层的腐蚀电位最高(?0.76 V)，腐蚀电流密度最小，为2.98×106 A/cm 2。Cu-DLC涂层腐蚀电位最低(?0.87 V)，腐蚀电流密度最大，为8.15×106 A/cm 2。针对海洋服役环境，双掺杂的Si/Cu-DLC兼具防腐和抗菌性能，可有效保护海洋装备设施，值得在海洋环境中应用推广。
Abstract:
Aiming at the Q235 steel commonly used in Marine equipment, in order to solve the problem of its corrosion failure, three groups of diamond-like carbon (DLC) coatings were prepared by the hollow cathode discharge technology of plasma immersion deposition (PIID), and the influence of Si and Cu element doping on the structure and corrosion resistance of DLC coatings was studied. Results show that the Si doped (Si-DLC) coating exhibits an amorphous structure, whereas both Cu doped (Cu-DLC) and Si/Cu co-doped (Si/Cu-DLC) coatings demonstrate composite architectures with nano-Cu crystalline phases embedded in an amorphous carbon matrix. Adhesion testing show a descending bonding strength order with Si-DLC(18.5 N)>Si/Cu-DLC(13.9 N)>Cu-DLC(9.4 N). Electrochemical measurements indicate that Si-DLC achieve the most noble corrosion potential (Ecorr) with the lowest current density (2.98×106 A/cm?), while Cu-DLC display the least favorable performance ( Ecorr= ?0.87 V, Jcorr=8.15×106 A/cm?). The co-doped Si/Cu-DLC coating demonstrate dual functionality, combining enhance corrosion resistance with inherent antibacterial properties attributed to copper incorporation. These results show that the Si/Cu-DLC system is particular promise for marine applications where synergistic resistance to chloride-induced corrosion and microbial attack is critical for equipment protection
