Description
図2は本発明の方法による受歯肉盛部の断面図であり、5の鋼製枠の中に肉盛部6が形成される。7は冷却水用の通路である。使用するに従い、摩耗が少しづつ進行するものであるが、本発明による肉盛溶接法による耐摩耗層は格子状の鋼製枠と併用することにより通常、不可能な厚みの肉盛を可能とすることができ、長期に使用に耐えることができ、極めて、有利なものである。
本実施例では合金粉末を用いたが合金粒でもよい。本発明方法に用いる合金粉末または合金粒は、50μm未満だと、飛散するため歩留りが悪くなり、500μm超だとノズルで供給不良が起こるため、50〜500μmの範囲が望ましい。

- 格子状に鋼製の枠を設けて、該枠内に肉盛溶接により受歯の耐摩耗層を形成した焼結クラッシャー受歯であって、受歯の耐摩耗層を少なくとも2重以上の多重成分層から形成し、該多重成分層はその肉盛溶接中にワイヤー電極とは別に、Cr、Mo,Nb、Vを含有する合金粉末または合金粒を溶接部溶融池に供給して形成されたものであることを特徴とする焼結クラッシャー受歯。
