microhardness of deposited P2M8 high-speed steel subjected to gas-laser cutting are …

Laser surface hardening of very low carbon steel of~ 1 mm thickness containing 0.05% and
0.07% carbon was carried out with a high power fiber laser. The microhardness increased …

A study of the laser surface hardening process of low carbon steel has been carried out. A
tiny lath martensite can be obtained in hardened zone and it can increase the hardness of …

Heat treating the surface of medium carbon steels to produce a hardened layer whilst
retaining a tough core is widespread throughout general engineering and may be …

The problems of surface hardening of high-carbon steels by alloying using laser radiation
are considered. The effect of the laser treatment parameters on the thickness, the structure …

An experimental investigation with Nd: YAG laser system was carried out to study the effects
of laser hardening process parameters on the microstructure and hardness during laser …

A CO2 continuous wave laser producing up to 2 kW continuous power over an area down to
2· 0 mm2 was used as a surface heater. The surface hardening of certain steels is possible …

Case hardening of a carbon steel, Armco Iron, an alloyed steel and a high-speed steel was
carried out with a CO 2 laser beam. The indispensibility of an absorptive coating in the laser …
