Overview

Indoor tests reveal corrosion mechanisms and protective coating performance in bolts exposed to mine water, suggesting better longevity strategies.

Key Points

  • Investigate corrosion mechanisms and protective strategies for anchor bolts in mine water environments.
  • Developed a corrosion test device and method using mine water as medium.
  • Analyzed electrochemical corrosion behavior of bolts in a controlled setting.
  • Compared the performance of various anti-corrosion coatings under accelerated corrosion conditions.
  • Corrosion process governed by dynamic rust layer evolution with phases of protection and eventual high rates of corrosion.
  • Surface changes include pits and cracks leading to reduced bolt durability and performance.
  • Chromium coating shows the best long-term corrosion resistance, while fluorocarbon and zinc coatings have varying effectiveness.
