Finite Difference Modeling on the Temperature Field of Consumable-Rod and Substrate in Friction Surfacing Process

  • V.Pitchi Raju


Friction surfacing is a solid state coating process with applications of wear and corrosion resistance coatings and also used for reclamation and repair of damaged and worn components. Friction surfacing is a kind of thermal processing technology, in which the temperature profile obtained and changes of temperature occurred in consumable rod and substrate are significant factors to obtain high quality of coatings. In the present work, the temperature fields of the consumable rod and substrate during the process are simulated by finite difference modeling method, And also heat source model of the consumable rod and substrate are established in friction surfacing process. The obtained results are consistence with experimental values. Reoccurring of the changes of temperature of both consumable rod and substrate while conducting friction surfacing process, hence furnishing theoretical information for the selection of primary technical factors in industrial engineering applications and which permits additional work for producing quality of coatings in friction surfacing process.
