Case Carburising is a process in which austenised ferrous metal is brought into contact with an environment of sufficient carbon potential to cause absorption of carbon at the surface, and by diffusion, to create a carbon concentration gradient between the surface and interior of the metal. The addition of carbon referen-tially to the surface layers of the steels followed by proper heat treatment develops the hard abrasive, wear resistant surface and as the core remains comparatively soft and tough the component as a whole shows high impact strength. Due to the residual stress pattern developed during the process the fatigue strength also improves.
