Abstract

Composite electrochemical coatings (CECs) based on zinc, modified with carbon nanotubes (CNTs) from an alkaline electrolyte in a pulsed electrolysis mode have been obtained. The microstructure and tribological properties of these CECs are investigated. It was found that the introduction of the dispersed CNT phase into the alkaline galvanizing electrolyte reduces the sliding friction coefficient of the forming coatings by a factor of 1.30–1.45. The corrosion–electrochemical behavior of zinc–CNT CECs in 0.5 M solution of H₂SO₄ has been described.

碱性电解质对碳纳米管修饰的锌基复合涂层的电化学沉积

摘要

已经获得了基于锌的复合电化学涂层（CEC），该复合涂层由碱性电解质以脉冲电解方式用碳纳米管（CNT）改性。研究了这些CEC的微观结构和摩擦学性能。结果发现，将分散的CNT相引入碱性镀锌电解液中，可将成形涂层的滑动摩擦系数降低1.30-1.45倍。已经描述了0.5M的H ₂ SO ₄溶液中锌-碳纳米管的腐蚀-电化学行为。
