The coatings deposited on the surface of a substrate of a material in powder form, by injection in a laser beam, they could have important advantages opposite coatings deposited with other technical. These advantages are a very important decrease of the porosity, an interval of thickness of wide covering, a higher coating hardness, treatment in located areas, etc. In this paper our investigation group presents the problems found utilising this technique: inadequate speed of the particles, unstableness of the powder flow rate, effect of the angle of injection and alterations on the powder flow caused by the protective gas of the laser focusing head. We also present the adopted solutions and the improvements that these solutions have supposed for the properties of the coatings. The influence of the laser processing parameters in the dilution and in the characteristics of the coating is also studied (height of the track, penetration, etc.). Our final objective is to contribute to the knowledge of this technique.
