The state of laser transformation hardening in surface modification of steel and its alloys is
reported in this review paper. The laser hardening process involves the use of high-intensity …

Laser surface hardening (LSH) is one of the most widely used surface hardening process
which can be applied to almost the whole range of metallic materials in today's applications …

This paper presents a laser surface modification process of AISI H13 tool steel using 0.09,
0.2 and 0.4 mm size of laser spot with an aim to increase hardness properties. A Rofin DC …

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 …

This research work is focused on both experimental and numerical analysis of laser surface
hardening of AISI M2 high speed tool steel. Experimental analysis aims at clarifying effect of …

Laser surface heat treatments comprise a wide variety of techniques by which hard and
wear-resistant layers can be obtained on surface without affecting the bulk material. It is …

Defining and controlling the absorption of the laser beam is important since all of the heating
energy is brought to the material through absorption. Even small variations in the absorption …
