Aluminum alloy is an non-ferrous materials with excellent mechanical charateristic,which are widely used in modern automobile industry,aerospace industry,the electronic communications industry,computer industry and other fields.However, aluminum have the active chemical properties, low standard electrode potential, and the surface will be easily forming about 1-3nm oxide film in dry air,therefore aluminum alloy have the poor corrosion resistance.In order to overcome the shortcomings,expanding the applications range,improve the useful life of the aluminum alloy,the surface treatment process is very important which can solve or improve the corrosion resistance of aluminum alloy[1].
This research use the mid frequency magnetron sputtering process to deposit the ZrN film on the aluminum alloy surface,using optical profilometer to measure the film thickness,and use the YWX/Q-250 type salt spray device to do the corrosion resistance test in accordance with the national standard GB/T10125-1997.Optimize the process parameters of nitrogen flow rate, sputtering time and sputtering temperature, and get the best corrosion resistance of ZrN film[2,3]. 1 Experimental materials and processes This experiment use 40×60mm,15×30mm aluminum alloy mirror panel as the deposition base which easy to do the corrosion resistance testing and measure the film thickness.Aluminum alloy mirror panels use the ultrasonic wave to clean, inject metal cleaning agent into cleaning agent, the temperature controlled at 50℃.After 10mins washing then use the ionized water to wash for 10 mins,and then use acetone wipe to dry,and finally with alcohol to blow dry.Do not use hands to contact the aluminum
Through the experiment, it obtained the best process of sputtering ZrN film on the aluminum alloy surface.It not only provides experience and technology to improve corrosion resistance of aluminum alloy parts and aluminum alloy products, but also provides a process and method for other poor corrosion resistance material, and has a broad theoretical research value and application value.
