The relationships between composition, microstructure and electrochemical properties are of fundamental importance in understanding the corrosion of multiphase materials and thus in aiding in the design of new materials. A local electrochemical test system which combines a capillary device with a photolithographic mask has been developed to investigate the local electrochemical properties of a predefined micron-sized area with greater reliability and versatility than existing approaches. Independent electrochemical measurements were conducted on the different phases of a 2205 duplex stainless steel in NaCl solution, demonstrating the feasibility of the developed test system.

结合光刻和毛细管技术进行局部电化学性能测量

组成，微观结构和电化学性能之间的关系对于理解多相材料的腐蚀并因此有助于新材料的设计至关重要。已经开发了将毛细管装置与光刻掩模相结合的局部电化学测试系统，以比现有方法具有更高的可靠性和多功能性来研究预定微米级区域的局部电化学性质。在NaCl溶液中对2205双相不锈钢的不同相进行了独立的电化学测量，证明了开发的测试系统的可行性。
