About the authors

Costel Dorel FLOREA

PhD Eng. with 10 ISI papers and more than 50 citations. Co-organizer of Safety in Industrial field Congres. The main contributions focused on improving the properties of the usual materials used for brake discs by alloying or by deposition of thin ceramic layers on the contact surface. He characterized the classic materials used to make brake discs and improving the mechanical and chemical characteristics of existing materials.
