为提高304不锈钢的耐腐蚀性能,采用料浆法在其表面制备片径为3μm与300nm的氮化硼纳米片(boron nitride nanoplate,BNNP)增强氧化铝胶黏陶瓷涂层。通过扫描电子显微镜(SEM)和光学接触角测量仪分析含不同片径BNNP涂层的微观形貌及表面疏水性能,并利用电化学工作站分析涂层在模拟海水介质下的电化学阻抗与极化曲线,研究BNNP片径和含量对涂层微观形貌与防腐蚀性能的影响及其作用机制。结果表明:涂层疏水性随着BNNP含量的增加而提高,且两种片径的涂层均在BNNP含量达到1.0%(质量分数)时展现出优异的疏水性能,其中添加片径为300nm BNNP的涂层性能提升更为显著,使涂层表面润湿角由38°提升至96.972°;其低频阻抗和自腐蚀电位分别达到最高值22500Ω·cm~2和0.344V,自腐蚀电流密度达到最低值1.12×10~(-7) A/cm~2,表明添加片径为300nm BNNP的涂层具有更好的隔绝腐蚀介质效果和耐腐蚀性能。 |

To improve the corrosion resistance of 304stainless steel,boron nitride nanoplatelet (BNNP)reinforced chemically bonded ceramic coatings with lateral sizes of 3μm and 300nm were prepared on the substrate surface by the slurry method.The surface hydrophobic properties of BNNP coatings with different lateral sizes were characterized by SEM and optical contact angle measurement. The corrosion behavior of the coatings under simulated seawater solution was revealed by an electrochemical workstation.The effects of BNNP lateral size and content on the coatings' microscopic morphology and corrosion protection properties and their mechanisms were investigated. The results show that the surface wetting angle of the coatings increases with the addition of BNNP, the coatings of both lateral sizes have excellent hydrophobicity at 1.0%(mass fraction,the same below)BNNP,and the coatings with 300nm BNNP have significant improvement,which increase the surface wetting angle of the coatings from 38°to 96.972°.The addition of BNNP improves the coating quality,fills the pores and cracks inside the coatings,and BNNP has good hydrophobicity,which actively contributes to the improvement of the hydrophobicity of the coatings.And 300nm BNNP has a better sealing effect,creating more nuclei and filling the voids between alumina particles and the adhesive.The coatings with the addition of 300nm BNNP at 1.0% have the highest low-frequency impedance and corrosion potential of 22500Ω·cm~2 and 0.344V,respectively,and the corrosion current density reaches the lowest value of 1.12×10~(-7) A/cm~2.The coatings prepared on the surface of the substrate create a physical barrier that effectively hinders the intrusion of corrosive media into the substrate.Compared with the original coatings,the surface morphology of the coatings with BNNP is denser after corrosion,reducing the defects such as pores and cracks in the coatings.BNNP is chemically stable and has good corrosion resistance,which can further delay and retart the corrosion reaction in the coatings and prevent the contact of the substrate with the corrosive medium.The addition of 300nm BNNP has smaller lateral sizes and a wider distribution range,thus better impeding the expansion of corrosion paths.There are fewer defects such as corrosion pits and holes on the surface.Therefore,the coatings with the addition of 300nm BNNP have a better effect on hindering the expansion of corrosion paths. |
