초록

Decarburized zone of metal tongue which is used in seat belt for automobiles was carbon-restoration quenched and tempered using nitrogen-methanol gaseous atmosphere. The effects of microstructure and mechanical properties of metal tongue on the effectiveness of carbon-restoration during tempering was studied. Metal tongue showed $20{\sim}30{\mu}m$ decarburized zone. However, after carbon-restoration, it has uniform microstructure and thus hardness without decarburized zone. Carbon-restoration quenching and tempering process resulted in better wear and corrosion resistances than quenching and tempering process.
