Laser Hardening (LH)
Laser hardening is a method of the surface modification by rapidly heating the treatment zone above the phase transition temperature and then cooling by heat removal into the internal volumes of the material.
Purpose:
- surface strengthening of parts operating at high loads and subject to rapid wear;
- increase of surface resistance to friction, corrosion, wear due to change of chemical and mechanical properties of part surface;
- growing volumetric parts.
Advantages:
- no need to use long-term heating furnaces;
- no deformation;
- complete control of the geometrical parameters of the treated surface zone and the degree of material strengthening;
- automated process control system, which enables to achieve high stability of part hardening parameters;
- the hardening process occurs due to intensive heat removal deep into the metal.
Application:
- mechanical engineering;
- oil and gas;
- chemistry and recycling;
- metallurgy;
- energy.
