Infrared (IR) thermography was used to measure thermal profiles in the coating, consumable rod, and substrate during friction surfacing. A sudden raise followed by a steady state in thermal profile was observed and attributed to viscous heat dissipation during plastic deformation. The retreating side of the coating experienced higher temperature compared to the advancing side, indicating that the hot plasticized metal is carried from the advancing side to the retreating side. © 2011 The Minerals, Metals & Materials Society and ASM International.
