Mechanical properties of Al-Si galvanic coating and its influence on resistance weldability of 22MnB5 steel
Popis výsledku v původním jazyce
Increase of quality and productivity in the same time are the most important in automotive industry. Use of high-strength steel 22MnB5 allows decrease of sheet metal thickness compared to standard steel. Commonly the steel 22MnB5 is welded with laser [1]. Use of this steel for spot resistance welding is not yet fully described. Steel 22MnB5 is coated with Al-Si galvanic coating for increasing high temperature oxidation resistance [2]. During hot stamping and subsequent heat treatment diffusion layer is created between coating and steel. The thickness of this layer is strongly dependent on temperature and time of heat process [3]. The paper deals with mechanical properties (chemical composition, indentation hardness) of this diffusion layer and Al-Si coating. Different thicknesses of diffusion layers were compared and its influence on weldability was described. Thin thicknesses have negligible effect on weldability, yet large thicknesses very negatively influence the weldability.
