Laser surface hardening makes use of the rapid and cooling cycles produced on metals
surfaces exposed to a scanning laser beam without affecting the bulk of the sample …

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 …

In this research, a systematic investigation on laser transformation hardening (LTH) process
is carried out on high-strength low-alloy medium carbon steel, EN25 using design of …

The paper presents a modelling of the laser hardening process by a high-power diode laser
(HPDL). Through numerical implementation into the finite element method (FEM) code …

A 3-D numerical model for pulsed laser transformation hardening (LTH) is developed using
the finite element method. In this model, laser spatial and temporal intensity distribution …

This paper presents an experimental investigation of laser surface transformation hardening
(LSTH) of 4340 steel spur gears using regression analysis. The experimental work is …

In gas heaters and other plasma devices that use tubular electrodes, the arc is rotated in
order to spread the heat load to the electrodes and to reduce their erosion. A method to …

The present paper is a contribution to the definition of optimal laser hardening conditions
with production rate as the main goal. When the part to be treated is given, the optimization …
