Energy efficiency in the Friction surfacing of carbon steels

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


The present work addresses a performance analysis study in the friction surfacing of AISI H13, AISI 1045 and AISI 1020 consumable rods over mild steel substrates. The influence of process parameters (forging force, travel and rotation speed) on bonding efficiency and deposition rate were investigated, contributing to establish a realistic comparison with other coating technologies. Power and specific energy consumption were compared for the present material combinations. Coatings were examined by optical microscopy, image processing techniques and hardness testing. Forging force enhances joining efficiency, while faster travel speeds improve deposition rates and overall process efficiency. Coating thickness is influenced by the type of consumable material, as the more resistant alloys yielded thinner layers. Deposition rates varied from 0.5 to 2 g/s. Specific energy consumption reaches around 4, 6 to 8 kJ/g, for the deposition of AISI 1020, AISI 1045 and AISI H13, respectively, as the friction surfacing of tougher carbon steels requires higher mechanical work.
