Grinding hardening,the technology of hardening steel piece surface with grinding heat instead of high or medium frequency induction hardening heat,can integrate grinding surface hardening.

Study on the Surface Strengthening Technique of Fast-growing Pinus massoniana Lumber;

Microstructure and properties of electrospark surface strengthening layers;

Application of plasma surface strengthening technique in tool and die;

With good performance of rigidity,wear resistance,self-lubrication and high-temperature resistance,the nanometer coatings and films are prosperous surface treatment technology in surface reinforcement of die & mould.

The application of the wearproof surfacing welding technology with the tungsten-carbide rod melted by oxygen-acetylene flame to dies' surface reinforcement was introduced.

With good performances of wear-resistance, self-lubrication and high-temperature-resistance, the nano compound coating is a prosperous surface treatment technology in surface reinforcement of injection moulds.

　In this paper, research progresses on Laser-concerned surface modification is reviewed, which include:①Technology and factors control.
