ABSTRACT:
A braking element which has an uninterrupted, unitary structure and is prepared in one step is provided. By coating a molding surface used to mold the braking element with a certain amount of nodularizing agent, the molten iron poured into the mold is transformed into an uninterrupted, unitary structure. The amount of nodularizing agent is such that a ductile iron support surface results from the nodularizing agent inoculating the initially poured iron. However, the amount is also such that a grey iron friction braking surface results from the subsequently poured iron which does not come in contact with the nodularizing agent.
