Description
ここで、本発明者等が行った実験Iを説明する。なお、この実験Iは、前述した脱Si,脱Mn処理工程P4において、温度T(℃)、圧力P(Pa)、保持時間t(分)の条件をそれぞれ変更することによって、そのシャフト10の表層から蒸発するSi、Mn、Crの量を好適に増加させられるすなわちその表層に含まれるSi、Mn、Crの量を好適に低減させられることを検証するための実験である。
y(mass%)=−0.0018×T(℃)+0.0001×P(Pa)−0.0242×t(分)+6.47677 ・・・(1)
ここで、本発明者等が行った実験IIを説明する。なお、この実験IIは、図2に示す製造工程P1乃至P5において脱Si,脱Mn処理工程P4によるシャフト10への影響すなわちそのシャフト10の表層に形成される粒界酸化層Aへの影響を検証するためのものである。なお、上記実験IIでは、シャフト10に形成される粒界酸化層Aによるそのシャフト10の疲労強度への影響も検証した。
