Abstract
Within this research project, basic
methods for an adjustment of mechanical properties via local
carburization have been developed. To accomplish this, the sheets of a
complex phase steel are coated with graphite and subsequently
heat-treated at temperatures between 900 °C and 950 °C. A suitable
process window was identified based on the influencing factors'
carburization time, carburization temperature and sheet thickness.
Afterwards, a detailed characterization of the transition zones between
carburized and non-carburized areas was conducted. Furthermore, this
research project seeked to analyze the additional coating's influence on
the heat transfer coefficient as well as verify the results by applying
them to a model geometry.
