- 粉末冶金における積層造形法による焼結体の製造方法であって、原料粉末に溶媒と第一の成形助剤を添加して、必要により混合粉砕して、スプレードライヤーで乾燥造粒することにより、第一の造粒粉末を得る工程と、第一の造粒粉末を、非酸化性気体の気流中で加熱して脱脂処理を行い、その後続けて仮焼結として加熱処理を行い固相焼結させることにより、第二の造粒粉末を得る工程と、第二の造粒粉末に、第二の成形助剤の粉末を共に固相のまま混合する工程と、この混合した第二の造粒粉末を、造形ステージに均一な薄層として敷詰める工程と、求める形状の積層方向について薄く切った断面形状に、選択的にレーザーを照射して、第二の成形助剤粉末のみを融解させ、その後自然冷却により凝固させる工程を複数回繰返して、求める形状の造形体を得る工程と、この造形体を脱脂処理、真空中または非酸化性雰囲気中で焼結、及びHIP処理を行う工程から構成されており、第一の造粒粉末を脱脂後に仮焼結として加熱する条件が、真空中、または非酸化性雰囲気中で、650℃以上1000℃以下の温度で、10min以上60min以下の保持時間であり、仮焼結による、第一の造粒粉末からの大きさの収縮が10%以内であることにより、造形体の焼結における収縮率を正確に求められるようにした、仮焼結では液相を出さずに固相焼結させるものである、求める形状の焼結体の製造方法。
- 第一の成形助剤は、融点が40℃以上80℃以下のパラフィンであり、原料粉末に対しての添加量が、0mass%以上5mass%以下である、請求項1の焼結体の製造方法。
- 第二の成形助剤は、融点が300℃以下の熱可塑性樹脂粉末、またはパラフィン粉末のいずれか一種類以上であり、第一の造粒粉末に対しての添加量が、5mass%以上10mass%以下である、請求項1または請求項2の焼結体の製造方法。
- 第一及び第二の造粒粉末として、粒度が20μm以上50μm以下の粉末を用いる、請求項1から請求項3のいずれかの焼結体の製造方法。
- 焼結体が、超硬合金、サーメット、タングステン基合金、銅−タングステン合金、または粉末高速度鋼である、請求項1から請求項4のいずれかの焼結体の製造方法。
- 焼結体が、超硬合金であり、粉末調製時の配合組成が、5mass%以上30mass%以下のCoおよび/またはNiと、(Co+Ni)に対して0mass%以上16mass%以下のCr3C2と、残部がWCと不可避不純物から構成される、請求項1から請求項5のいずれかの焼結体の製造方法。
