Abstract

Laser Direct Materials Deposition(LDMD) is one of new emerging techniques of Rapid Manufacturing(RM) supported by CAD/CAM in recent years. Although LDMD shows great potential for many industrial applications, low powder efficiency about 30% due to canying gas increases cost of production and limits its application. In this paper, based on the Beer-Lambert law, the concentration ofpowder and the beam attenuation in co-axial feed powder laser cladding are researched. The relationship of the attenuation and laser cladding parameters, such as the laser power. a new co-axial powder feeder without carrying gas for LDMD was developed. Preliminary research on LDMD was achieved by non-carrying gas powder feeder.
