Abstract

The work aims to explore the influence of activating elements on the electrochemical performance of zinc alloy sacrificial anodes to meet the cathodic protection requirements of high-strength steel materials for deep diving equipment. A new type of zinc alloy sacrificial anode was prepared according to the alloying design method to control the activation elements. Through conventional electrochemical performance tests, electrochemical tests, scanning Kelvin probe test data, and microstructure characterization results, the influence of activation elements on the microstructure and comprehensive properties of zinc alloy sacrificial anodes was comprehensively analyzed, and the changes in the performance of low driving potential zinc alloy sacrificial anodes were explored. The surface dissolution morphology of the sacrificial anode added with Ga, Mn, Sn, and Cd activation elements was relatively uniform, and the anode potential underwent different degrees of positive shift. When used for cathodic protection, the driving potential was reduced, and its working potential was basically within the range of -1.02~-0.8 V (vs. Ag/AgCl). The sacrificial sample showed a trend of decreased surface dissolution activity and slower dissolution rate. By adding various activating elements, the sacrificial anode performance of zinc alloy is optimized and improved to varying degrees. Cd element can increase the surface disorder of the anode sample, and the grain size of the sacrificial anode sample is refined to a certain extent with the increase of Sn and Mn content. Among them, the Zn-0.5Mn series sacrificial anode better meets the cathodic protection requirements of high-strength steel, with a working potential of -0.95~-0.84 V (vs. Ag/AgCl) and a uniform distribution of surface active sites. Further development of new sacrificial anodes suitable for cathodic protection of high-strength steel structural materials is possible.
