The artificial neural network methodology has been developed for the virtual simulation of the laser surface hardening process for blanket dies.

The quality of laser surface hardening ( LSH) is depended strongly on the intensity distribution.

The paper mainly deals with the decisive factors influencing hardening quality in surface hardening treatment with laser.

Study on the laser surface hardening technology of 4Cr13 stainless steel;

Effects of laser surface hardening on microstructure and hardness of high Ni-Cr indefinite chill cast iron roll

In the paper, the surface treating technologies are divided into three classes, and then the technologies such as NQN compound reinforcement, rare earth surface hardening, laser surface hardening, electro spark deposition of ceramet, chemical compound plating, etc.

Microstructure and property of TiC/Ti composite coating by laser surface alloying;

Research development of laser surface alloying on ferrous substrate;

The Study of the Crack on Laser Surface Alloying;

Proceed in the point of riew to make the hardfacing alloy's absorptivity of Laser beam in -crease and make the total input of heat to them de-crease, the dielectrics act characteristics and its re-strainning role to the hot cracks in high temperaturealloy's laser hardfacing is studied.
