Technological complexes MLS-XXX are designed for surface laser-thermal hardening of end, flat and radial surfaces of rotation parts, as well as any curved surfaces, including involute engagement. The complex strengthens the inner and outer cylindrical surfaces, splines.

Laser surface thermal hardening of metal parts is a promising technological process that increases the service life of machine parts and tools.
Laser hardening is carried out by treating the part with a defocused laser beam, which causes high-speed heating of the surface layer, while the product itself remains practically cold. After the termination of the action of radiation, heat is transferred at high speed deep into the metal, and the surface layer is quenched. As a result of laser exposure on the surface of steel or cast iron, specific structures are formed with increased hardness and wear resistance, which cannot be obtained by traditional methods of heat treatment. Having processed the wear surface of the part or the cutting edge of a stamping or cutting tool with a laser beam, their hardness can be significantly increased to 60-70 HRC. The depth of the hardened layer reaches 0.4 - 0.6 mm. Herewith, the wear resistance of cast iron parts hardened by a laser beam increases by 5-8 times. and the rest - by 2-4 times in comparison with traditional methods of heat treatment in chemical-thermal treatment, the resistance of stamping and cutting tools increases by 1.5 - 3 times.
Compared to traditional heat treatment methods, laser hardening is characterized by low specific energy consumption, the possibility of local hardening of the surface area of ​​the required size and hard-to-reach spots, provides minimal warpage, the absence of quenching media and harmful waste, and a high level of automation.
Laser hardening is recommended for hardening the wearing surfaces of new and reconditioned parts in automotive and mechanical engineering.
