Title:
PRODUCTION METHOD AND PRODUCTION DEVICE FOR A COMPOSITE METAL POWDER USING THE GAS SPRAYING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/074720
Kind Code:
A1
Abstract:
The present invention relates to a production method and a production device for a composite metal powder using the gas spraying method, and more specifically to a production method for a composite metal powder using the gas spraying method, comprising the steps of: introducing a matrix phase into a chamber; providing a reinforcing phase in the chamber; forming a melt pool by melting the matrix phase which was introduced; adding the reinforcing phase to the melt pool; forming a mixed melt pool by stirring the melt pool into which the reinforcing phase was added; forming a composite metal powder which contains the reinforcing phase by spraying a gas together with the mixed melt pool; and recovering the composite metal powder so formed; and relates to a production device for a composite metal powder using the gas spraying method, comprising: an upper chamber on the inside of which is provided a crucible where the matrix phase is introduced and melted; an introduction means provided above the crucible on the inside of the chamber, so as to allow the reinforcing phase to be selectively introduced into the crucible; a stirring means for stirring the melt pool formed by heating the inside of the crucible and the reinforcing phase introduced into the crucible via the introduction means; a spraying nozzle for producing a powder by spraying a gas together with the mixed melt pool formed by using the stirring means to stir the melt pool and the reinforcing phase; and a lower chamber constituting a recovery area for the composite metal powder produced by means of the spraying nozzle; and also relates to a production method for a composite metal powder using the gas spraying method, comprising the steps of: (Step 1) either producing a melt pool by heating and so melting an aluminium ingot or an Al-Si based alloy comprising the reinforcing phase and then adding a metal ingot, alloy ingot or aluminium-reinforcing phase powder and stirring, or producing a melt pool by subjecting an aluminium/reinforcing phase powder to Al-foiling and then charging at the bottom end of an aluminium parent material and heating and stirring; and (Step 2) producing a composite metal powder by spraying a gas together with the melt pool produced in Step 1.
