Process developments in friction surfacing for coatings applications

Abstract

The present work focused on the production of coatings of AISI1024, AISI1045 and AISIH13 overmild steel and AA6082-T6 over AA2024-T3 by friction surfacing. Performance criteria were established to quantify material deposition rate and specific energy consumption aiming to compare friction surfacing with most direct concurrent technologies such as laser and arc welding based cladding. Simple analytical modelswere developed to estimate the rod consumption and the power and energy consumption rates. Friction surfacing is a competitive technology considering energy efficiency and power consumption in comparison with mainstream processes. However, coating processes based on wire or powder feed aremore competitive, since they allowcontinuous feeding of depositedmaterial. The effect of process parameters was also assessed and it was seen they have different impacts on process efficiency and deposition rate for each material combination.
