Influence of process parameters of oxygen cold plasma treatment on wettability ageing time of 2024 aluminium alloy

摘要: Abstract 2024 aluminium alloy is widely used in aeronautical applications because it provides a high mechanical strength and low weight. Aeronautical critical environmental conditions cause corrosion on the surface part, due to Cu present Al2024. To solve problems associated with corrosion, commonly covered by paint; important guarantee adhesion of paint coating stability course time. achieve this aim must be prepared before applying protective coating. Cold plasma treatment represents an efficient, non-polluting economical alternative clean activate surfaces. In particular, has been demonstrated that oxygen cold improves wettability Al2024 surface. The work value ageing time surfaces treated plasma. evaluation fundamental step plan insertion process inside industrial process. fact, once determined, possible establish how much pass between activation body, obtained treatment, following
