Abstract:
Processes for protecting steel chains from corrosion and steel chains thus protected are provided. The process includes using finite element analysis to determine stress levels within links of a steel chain having a plurality of connected links. Regions of each link of the chain corresponding to high stress levels are identified. Target areas corresponding to the regions identified are indicated for coating each link of the chain with a sacrificial coating. Thermally sprayed alumina can be used as the sacrificial coating.
