A 1050 알루미늄과 SS41 軟鋼과의 브레이징 接合에 關한 硏究 = A Study on the Brazed bonding of A 1050 Aluminum to SS41 Mild Steel

다국어 초록 (Multilingual Abstract)

The Purpose of this study is to investigate the effect of Ni plating layer thickness and lap ratio on the bonding strength of the brazed bonding of Al/SS41.
The brazing was performed under different bonding conditions such as Ni plating thickness and lap ratio. The bonding strength was evaluated by tensile tester and micro-structural analysis at the interlayer was performed by SEM. In order to improve the bonding strength, the metallic plating of Ni on the SS41 surface was used. Using the metallic plating of Ni on the SS41 surface, the wettability between filler metal and base metal was improved, therefore bonding strength was increased.
An optimum lap ratio obtained through the experimental results was 3.0 in case of 10㎛ Ni plating thickness.
