CARBIDE POWDER PRODUCTION METHOD AND CARBIDE POWDER PRODUCTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a carbide powder production method by which a carbide powder having a sufficiently increased content percentage of carbon can be obtained.;SOLUTION: A carbide powder production method includes: a forming step of forming a thin layer 104 of a raw material powder; and a carbonizing step of applying an AC voltage to the thin layer 104 formed in the forming step to generate plasma in an atmosphere containing carbon with reduced oxygen so as to carbonize the raw material powder of the thin layer 104. By the method, a carbide powder having an increased content percentage of carbon can be obtained; and for example, hardness of a molded object molded by powder bed melt-binding technology using the above carbide powder can be increased.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
