The friction surfacing method entails the rotation of a filler rod under an axial load applied on a surfacing plate, which in turn gives rise to the generation of heat at the rotational plane and a softened rod metal is deposited as a surfaced metal on the plate. The surfaced metal of fixed thickness is attained during the heating hold process, then the plate moves laterally so that the surfaced metal is continuously deposited on the moving plate just like a bead of the arc welding. This method can be used for repairing local or surface damage of the work. After a detailed observation of the plastic flow at the friction surfacing parts using a tracer, this report revealed that metal at the central part of the filler rod formed the surfaced metal and one at the periphery did the flash. At that time, the central part of the rotational plane was travelling to the filler rod so that the surfaced metal was furishing. Then an author defined this central part of the rotational plane as the real rotational contact plane. The characterists of the real rotational contact plane was also revealed in subsequent experiments that the area of the real rotational contact plane decreased with increasing rotational speed and friction pressure. Calculations for the diameters of the real rotational contact plane were carried out from the mass of the surfaced metal and the length of the consumed rod.
