Abstract:
Based on the fact that cold spraying(CS)was increasingly attracting more and more attention from researchers worldwide,this paper made detailed summarization and discussion on fabricating composite coatings via CS according to the published literature.Firstly,the powder preparation methods prior to spraying and the effects of processing parameters on deposition of composite coatings were explored.And then,the fabrication of metal-metal,metal-ceramic,metal-intermetallics and nano-composite coatings were summarized.Eventually,the present problems and potential applications existing in composite coatings fabricated by CS were discussed.
Key words:cold spraying;composite powder;process parameter;composite coating
