| Abstract: |
| Aiming at the increasingly serious corrosion situation of all kinds of steel components in the marine environment, the cold spraying was increasingly attracting more and more attention from researchers worldwide in view of the coating defects of traditional hot spraying technology such as high porosity, large thermal stress, etc. that couldn’t be solved. This paper made detailed summarization and discussion on fabricating coatings via cold spraying according to the published literature. Firstly, the advantages and feasibilities of fabricating metallic coatings, nonmetallic coatings and composite coatings were explored in comparison with the technical characteristics of traditional thermal spraying. Meanwhile, the anticorrosion mechanism of metal coatings and composite coatings were revealed from the perspective of electrochemical corrosion, and all kinds of rational analysis of non-metallic coating anticorrosive mechanism were indicated. And then, the fabrications of metallic coatings, nonmetallic coatings and composite coatings were summarized from the coating porosity, electrochemical properties (including the corrosion potential and corrosion current, etc.) and specific application environment of anticorrosion properties characterization of corrosion test and so on. The anti-corrosion coating technology of cold spraying was gradually mature. Furthermore, non-metallic coatings made the transition from laboratory research and development stage to industrial applications compared with metal and composite coatings. Eventually, the present problems and potential applications existing in anticorrosion coatings fabricated by cold spraying were discussed. |
