On characterizing microscopically the adhesion interphase for the adhesion between metal and rubber compound Part II. Effect of copper content for brass-plated steel cord

Abstract

To cite this article: Gyung Soo Jeon (2014) On characterizing microscopically the adhesion interphase for the adhesion between metal and rubber compound Part II. Effect of copper content for brass-plated steel cord, Three brass-plated steel cords with different copper contents from 51.4 to 75.5% were prepared and their adhesion properties to rubber compound were examined. Adhesion properties improved with the decrease in the copper content. The high adhesion of brass-plated steel cord with low copper content to the rubber was obtained after cure and after hostile aging treatments. The stability against humidity aging and the cause for the high adhesion of the brass-plated steel cord with low copper content were discussed in conjunction with the formation and growth of adhesion interphase determined by Auger electron spectroscopy depth profile. The excellent adhesion stability of brass-plated cord with low copper content can be explained by the suppression of the excessive growth of copper sulfide and the inhibition of dezincification due to the low copper content.

Hydrothermal Aging Mechanisms of All-Steel Radial Tire Composites

“…Kenichi et al [ 20 ] studied the degradation of rubber-to-brass adhesion by high-resolution photoelectron spectroscopy in a hydrothermal environment. On the contrary, Jeon et al [ 21 ] stated that the copper plating on the steel wire can react with the rubber to produce sulfide during the vulcanization stage to promote interfacial bonding. To date, the effects of hydrothermal aging on the properties of ASRT composites, for example, the change of cross-link density and interface properties, are still not clear, which limited its applications.…”
