Large gear components can be offered in many applications such as in marine, wind power, steel rolling
mills, power plants, transportation, railroad, aircraft, cement crushers, mining and oil industry applications.
There are three important surface hardening methods used to improve and expand the technical use of
gear components. Design and material engineers must decide which hardening method to use. Case
hardening is normally the first choice because of the highest load capacity. But, case hardening also
poses challenges that must be acknowledged. Therefore, it is good to know that there are three options
for very large components.
