摘要

本研究通过在3.5% % NaCl溶液中检测Cr/CrN多层涂层的局部表面电子性能、纳米力学行为和电化学活性，详细了解了沉积在钢上的Cr/CrN多层涂层的微观结构和形态特征与腐蚀行为的相关性。研究的重点是物理化学表面演变对Cr/CrN涂层纳米力学性能的影响。这是通过将电化学阻抗谱（EIS）的电化学数据与x射线光电子能谱（XPS）和纳米压痕分析的结果相关联来研究的。综合方法揭示了涂层的物理化学演变及其在苛刻环境中的耐腐蚀性。

A combined microstructural, electrochemical and nanomechanical study of the corrosion and passivation properties of a Cr/CrN multilayer coating

This research provides detailed insights into the correlation of microstructural and morphological characteristics of a Cr/CrN multilayer coating deposited onto steel and its corrosion behavior, by examining its local surface electronic properties, nanomechanical behavior, and electrochemical activity in a 3.5 % NaCl solution. A key focus of the study is the influence of physicochemical surface evolution on nano-mechanical properties of Cr/CrN coating. This is investigated by correlating electrochemical data from electrochemical impedance spectroscopy (EIS) with findings from X-ray photoelectron spectroscopy (XPS) and nanoindentation analysis. The integrated approach shed light on physicochemical evolution of the coating, and its resistance to corrosion in demanding environments.
