[実施例2]
ろう付け接合部の分析
Tiと同様、超硬合金に隣接するCが見られない。しかしながら、元素Tiを含む非常に薄い層が見られる。SEM-BSE画像に透明な薄層が見られる。したがって、非常に薄いTiCの第1層が存在する。
第2層は、相当量のNi、CuおよびTiを含有する。しかしながら、層は非常に不均一であり、いくつかの相を含み、画定が不十分である。
超硬合金の最上部にNi欠乏領域が見られない。
Tiと同様、超硬合金に隣接するCが明確に見える。SEM-BSE画像に透明な層が見られる。したがって、TiCの第1層が存在する。
第2層は、相当量のNi、CuおよびTiを含有し、十分に画定される。
超硬合金の最上部に約1μmのNi欠乏領域が見られる。
Tiと同様、超硬合金に隣接するCが明確に見える。SEM-BSE画像に透明な層が見られる。したがって、TiCの第1層が存在する。
第2層は、相当量のNi、CuおよびTiを含有し、十分に画定される。
超硬合金の最上部に約2μmのNi欠乏領域が見られる。
表3
*いくつかの相、画定が不十分な層、平均金属元素含有量および層の厚さの測定が困難である
**金属元素が存在するが、いくつかの相中にあり、平均含有量を測定することが困難である
