Abstract: A method provides a device having a feeder vessel, a building vessel with a bottom and a fabrication plate that is movable in vertical translation, a transfer system suitable for depositing powder from the feeder vessel to the building vessel as a powder layer of constant thickness, and a high energy beam optical system suitable for scanning the surface of the deposited powder layer. A powder is placed in the feeder vessel. A first series of powder layers is deposited on the fabrication plate. The particles of powder are melted or sintered to form a plurality of columns of material that are separated from one another by particles of powder. A second series of layers of powder is deposited on the first series of layers of powder particles to form a single-piece element. A thermal insulation platform is formed between the fabrication plate and said single-piece element.

Abstract: A low-temperature stainless steel carburization method comprises steps: providing a stainless steel material; placing the stainless steel material in a halogen-free reducing environment and maintaining the stainless steel at a first temperature ranging 1,050 to 1,400° C.; and placing the stainless steel material in a carbon-bearing atmosphere and maintaining the stainless steel material at a second temperature lower than 600° C. to implant carbon atoms into the stainless steel material to form a carburized layer on the surface of the stainless steel material. A halide-bearing gas or solution is not to be applied to activate the passivation layer, so the fabrication cost would be reduced and the safety of carburization process would be enhanced. Besides, the environment can be prevented from halide pollution.
