What is corrosion fatigue in rock drilling components?
Corrosion fatigue is a common failure mechanism in rock drilling components and many other mechanical parts subjected to cyclic loads in corrosive environments.
What is the purpose of the corrosion-fatigue testing method?
The present work was performed with the purpose of designing a corrosion-fatigue testing method that would allow the designer to compare the performance of different materials exposed to corrosion fatigue, permitting also the comparison with results from dry fatigue testing. The method was designed for rotating-bending machines.
