Abstract

The changes in adhesion interface between rubber compound and brass plated steel cord after various aging treatments were studied by using an Auger electron spectrometer and a scanning electron microscope. After thermal aging, partial oxidation and additional growth of adhesion layer were observed. The adhesion layer and brass were partially removed after humid aging. With dynamic aging the adhesion layer was destroyed and the corrosion of steel core was proceeded. The changes in adhesion interface were discussed in terms of the adhesion properties determined from the stress-strain experiments.

열화처리 후 고무와 황동이 피복된 강선코드의 접박계면 변화를 오제 광전자 분광기와 주사 전자현미경으로 조사하였다. 열열화 후에는 접착층의 부분 산화와 추가 성장이, 습윤열화 후에는 접착층과 황동의 부분 소실이, 동적열화 후에는 접착층의 파괴와 철심의 부식이 관찰되었다. 이러한 접착계면의 변화를 인장시험에서 측정된 접착 성질과 관련지어 고찰하였다.
