절삭공구용 초경합금의 성형체 및 소결체의 강도에 미치는 성형조건의 영향
Effect of the Forming Condition on Flexural Strength of Green and Sintered Bodies of Tungsten Carbide for Cutting Tool
초록
The effects of forming presure, organic binder content and moisture on flexural strength were investigated. As moisture content increased in the granules during compaction, the density and strength of the green body were increased. Green strengths were found to improve more strongly with increasing forming pressure in the case of using the granules of higher organic content. The sintered strength was the highest with the organic content of 0.2wt% under all forming pressures.
