Fracture Surface Analysis of Borosilicate Bonded Stainless Steel

Abstract

Borosilicate glass was bonded to the stainless steel (st.st.) grade 316 by using a technique of oxides growth considered as active filler. Contact angle of oxide to the stainless steel was found 47ᵒ. The bonding strength achieved under ambient condition enriched with oxygen, and is equal to 4 MPa. The good bonding was correlated with new structural phases at the intermediate layer. The bubbles size and their amount were found as important factors play a significant role in bonding borosilicate and stainless steel
