Abstract
The present work examines the feasibility of getting friction surfaced coatings on different combinations of consumable rods and non-ferrous substrates. Aluminium (AA1050A), Copper, Stainless Steel (AISI 304), Mild Steel were used as substrates and commercially pure Copper and Stainless Steel (AISI 304) were used as consumable rods. Friction surfacing was carried out using these consumable rods and substrate combinations with a conventional universal milling machine FNU2213. The investigation revealed that certain combinations metallurgically bonded coating is formed quickly over the substrate while with certain other combinations, this coating is formed with the assistance of a start-up plate. However, for a certain combination of parameters, no coating is formed whatsoever. The formation of coating is influenced by the coefficient of friction as well as material properties, such as, thermal conductivity and stability at high temperature.
