Mechanistic Study of Silane Assisted Rubber to Brass Bonding and the Effect of Alkaline Pre Treatment of Aluminum 2024 T3 on Silane Performance

by Nookala, RamaKrishna

Abstract (Summary)
This thesis explores two independent topics-the effect of silane on adhesion between rubber and brass and the effect of pre-treatment of Al 2024 T3 on silane performance.In the investigation of the effect of a silane mixture on the adhesion between brass and natural rubber, TOFSIMS was used to characterize the brass panels that were subjected to vulcanization in squalene of different formulations. Based on the characterization data it was concluded that the sulfur based silane assisted in the formation of copper sulfides in squalene formulations with low levels of sulfur and cobalt.DCP and XPS techniques were employed to assess the effect of alkaline pretreatment of aluminum on silane performance. Based on the decrease in corrosion current of the silane coated aluminum substrate with decreasing molarity of the pretreatment solution it can concluded that there exists a correlation between aluminum pretreatment and silane performance.
