METHOD FOR CARBON COATING CARBIDE-METAL CERMET POWDER |
摘要 |
The method according to the present invention consists of step mixing the carbide-metal cermet powder and wax which is a polymer of carbon-hydrogen, step heating primarily the mixed material from the atmosphere temperature to 200-400 deg.C for 0.5 - 1 hours, step heating secondary it to 400-800 deg.C under the inert or reduce gas condition. The method according to the present invention control the carbon amount into not more than 3% and improve the quality of the wear endurance part.
