Finite difference modeling on the temperature field of consumable-rod in friction surfacing

Friction surfacing is an advanced process of great potential, especially in the field of repair and reclamation of worn and damaged components. The temperature field of consumable-rod in friction surfacing, as a kind of thermal processing technology, is an important factor in the successful implementation of the process. In this paper, the heat source model of consumable-rod in friction surfacing is established, by which the temperature field of consumable-rod during the process is simulated through finite difference method. The results are consistent with experiments, reappearing the temperature field of consumable-rod during friction surfacing, thus providing theoretical guidance in the choice for key technical parameters in engineering practice.
