The invention discloses a
laser-induction
hybrid melting direct forming method and device. The
laser-induction
hybrid melting direct forming method comprises the following steps of: generating a three-dimensional model of a part through CAD (Computer-Aided Design)
software, and then
slicing the three-dimensional model and generating a
G code to drive a
numerical control system and a base body to move; and melting synchronously fed
metal or
metal /
ceramic hybrid powder through a high-power
laser beam and an induction heat source, and depositing the three-dimensional part in a designed shape layer by layer, wherein a temperature controller is used for monitoring and controlling the temperature of the base body in the
processing process. The device for realizing the laser-induction hybrid melting direct forming method comprises a laser, a light
path system, an
induction heating and
temperature control system, a
powder feed
system and the
numerical control system. The device can be used for directly generating large and medium size three-dimensional parts on various
metal base bodies, has the advantages of high
processing efficiency, compact part structure, fine crystalline grain, excellent
mechanical property, less
residual stress without deformation or
cracking phenomenon, high
processing flexibility without tools and moulds, high material utilization ratio, cleanness without
pollution and capability of designing the components of a metal-
ceramic hybrid layer as required and even changing the components in a gradient manner.
