Abstract
【解決手段】超硬合金10の改質方法は、超硬合金10に摩擦攪拌プロセス用ツール30によって摩擦攪拌プロセスを施し、該超硬合金10に含まれる結合相の結晶粒を微細化するものである。特に、溶射法を用いて金属基材の表面に形成された超硬合金層に摩擦攪拌プロセスを施すことで、効果的に改質を達成することができる。
【選択図】図1
Description
Welding Institute)で考案された接合技術である摩擦攪拌接合法を、金属材の表面改質法として応用したものである。摩擦攪拌接合は高速で回転する円柱状のツールを接合したい領域に圧入(ツール底面にプローブと呼ばれる突起を有しており、該プローブが圧入される)し、摩擦熱によって軟化した被接合材を攪拌しながら接合したい方向に走査することで接合を達成する技術である。回転するツールによって攪拌された領域は一般的に攪拌部と呼ばれ、接合条件によっては材料の均質化および結晶粒径の減少に伴う機械的特性の向上がもたらされる。摩擦攪拌による材料の均質化および結晶粒径の減少に伴う機械的特性の向上を表面改質として用いる技術が摩擦攪拌プロセスであり、近年広く研究の対象になっている。なお、本発明で用いる摩擦攪拌プロセス用ツール30の底面には、必ずしもプローブを有している必要はなく、プローブを有さない所謂フラットツールを用いることができる。
実施例1(溶射超硬合金層の形成)
SKD61板材に対し、高速フレーム溶射法を用いて溶射超硬合金層を形成させた。原料粉末にはガスアトマイズ法で製造された平均粒径40μmのWC−20mass%CrC−7mass%Ni粒子を用いた。
SKD61板材に対し、高速フレーム溶射法を用いて溶射超硬合金層(WC−20mass%CrC−7mass%Ni)を形成させた後、該溶射超硬合金層に対して摩擦攪拌プロセスを施した。摩擦攪拌プロセスには直径が12mmの円柱形状をした超硬合金(WC−Co)製のツールを用い、600rpmの速度で回転する該ツールを3400kgの荷重で溶射超硬合金層に圧入させた。ツールの移動速度は50mm/minとし、アルゴンガスをフローさせることでツールおよび試料の酸化を防止した。
