Cementation Analysis by Eddy Current Method

Increase the hardness, the endurance and the life time of material can be realised by surface treatments and remetallings, the electromagnetic properties of steels depend on their composition, their microstructures and constraints applied. We can use the electric and magnetic parameters to evaluate their microstructure. The object of this work is the characterization of cementation by the nondestructive methods and the determination of physicochemical parameters. Samples of low carbon tenor steel were cemented with different alternatives. We studied these samples by eddy current method. The treatment of these results will be able to inform us about the cementation parameters. This work allow to determine the surface layers by NDT methods.
