EVALUATION OF WEAR AND CORROSION RESISTANCE OF TITANIUM AND STAINLESS STEEL JOINTS Made OF Al, Cu AND Ni
Journal Title: Tribologia - Year 2018, Vol 282, Issue 6
Abstract
In the present study, commercial pure titanium (Grade 2) was joined to the stainless steel (X5CrNi18-10) by diffusion bonding using aluminium, copper, and nickel as interlayers (100 μm). The investigation focuses on comparing the wear and corrosion resistance of the obtained diffusion joints. The microstructure of the joints was investigated using scanning electron microscopy equipped with an energy dispersive X-ray system (EDS) to determine the chemical composition of joint. The value of friction force and the wear resistance of diffusion bonded joints were carried out by block-on-ring frictional pair, preformed on the tribological tester T-05. The study was carried out under conditions of technically dry friction for the concentrated sliding contact loaded with 300 N. The friction distance for each test was 400 m. The results show that the maximum values of the friction coefficient and mass loss were obtained for joints with a nickel interlayer. The galvanic corrosion tests were carried out in 0.5 M Na2SO4 solution acidified to pH 1 with a sulphuric acid solution. The potentiodynamic polarization curves show that the lowest corrosion current was registered for the joints performed by copper.<br/><br/>
