Cementing is the process of mixing a slurry of cement, cement additives and water and pumping it down through casing to critical points in the annulus around the casing or in the open hole below the casing string. The two principal functions of the cementing process are: To restrict fluid movement between the formations.

The cementation is a unique process that allows the hardening of steel surfaces without losing the ductility of the core part One of the most old process for hardening of steel surface, but largely applied for axles and cams, it can be used in brass and copper, but its more common in steel Parts made of steel with medium or high percentage of carbon that will suffer severe bending operations
