COMBINATION OF COPPER INTERMEDIATE SX STEEL AND GR5 (Ti6Al4V) TITANIUM BY DIFFUSION WELDING METHOD
Öz
GR5 (Ti6Al4V) is a material commonly used in aerospace and space, biomedical and automobile sectors, consisting of pure titanium at a minimum of 99% purity. Besides being lightweight, GR5 is separate from similar materials with its ability to resist corrosion at high levels and show high strength. SX steel is high silicon-content austenitic stainless steel with the ability of good quality of welding and excellent corrosion resistance in high concentration sulfuric acid and nitric acid. SX is used in areas such as acid coolers, acid piping systems, acid distributors, acid towers and tanks, pumps, nozzles, internals, strainers and mesh pads. With improving technology, the need for steel-titanium materials that are resisted to acid and made with welded joint is increasing. In this study, the effect of GR and SX materials of welding temperature on the connection is examined with diffusion welding method using copper intermediary layer. The material pairs are combined with a pressure of 5 MPa and a fixed welding time of 60 minutes in an argon gas environment in a silicon bar oven at the temperature of 980, 1000 and 1020°C. The SEM-EDS-AFM analysis of the combined samples is performed, the metallographic structure of the intermediary layer in the diffusion-affected region is examined by the optical microscope, and the possible phases are tried to be determined by the XRD analysis. The micro stiffness values of the connection area are analyzed.
