# The Galvanic Corrosion of AM60B Coupled with DC01 in Simulated Environments with Varying Water Salinity

## TL;DR

This study examines how AM60B magnesium alloy corrodes when paired with DC01 steel in salty water environments.

## Contribution

The study reveals how salt concentration affects the corrosion rate and behavior of AM60B when coupled with DC01.

## Key findings

- DC01 significantly accelerates the corrosion rate of AM60B.
- Higher salt concentration intensifies the deterioration of AM60B.
- Mg(OH)2 formed during corrosion offers minimal protection to AM60B.

## Abstract

The galvanic corrosion performance of AM60B coupled to DC01 was characterized in simulated environments with varying water salinity. The results showed that the coupled DC01 effectively accelerated the corrosion rate of AM60B, and the increased salt concentration had a significant effect on the deterioration process. The corrosion of AM60B mainly exhibits metal dissolution, and the formed Mg(OH)2 has weak a protective effect on the alloy substrate. Furthermore, the distributions of the corrosion potential and the corrosion current density of the AM60B/DC01 couple were simulated and intensively discussed.
