Laser surface treatment-transformation hardening, Mechanical Engineering

Transformation Hardening

The main features of the laser as a heat source for transformation hardening are:

(A) Clean energy source.

(B) Energy is localised: no heat spillage.

(C) Only surface layer heated: core properties are unaltered.

(D) Low heat input: therefore low thermal distortion.

(E) Fast process: therefore no oxidation. The process can be a final operation.

(F) Self quenching: no water or oil sprays.

(G) Easily automated: the laser fits naturally into a numerically controlled system with time sharing between work stations.
