ADDITIVE MANUFACTURING METHOD AND DEVICE FOR CERAMIC AND COMPOSITE THEREOF
The present invention belongs to the field of additive manufacturing (AM) of high-melting-point materials, and particularly discloses an AM method and device for a ceramic and a composite thereof. The method includes: S1: slicing a three-dimensional (3D) computer-aided design (CAD) model of a workpiece to be formed into layers; S2: generating computer numeral control (CNC) codes for forming the slice layers; S3: preheating a substrate, and performing spraying deposition layer by layer according to the CNC codes of the slice layers; at the same time, heating a spray area till the spraying deposition of all slice layers is completed, and obtaining a formed part; and S4: subjecting a formed part to surface modification treatment by using a laser shock peening (LSP) method. The present invention obtains a formed part with stable microstructure and performance and high manufacturing accuracy, and is therefore particularly suitable for the AM of high-melting-point materials such as ceramics and ceramic-metal composites.
