摘要
Metallic magnesium and its alloys,as new types of metallic structural materials,show great application potential in fields such as aerospace,electronics,and biomedicine.However,magnesium is chemically active and highly susceptible to oxidation and corrosion in various environmental conditions,which can compromise its structural integrity and significantly reduce its service life.Therefore,it is of great significance to strengthen the development and application of corrosion protection technology for magnesium materials.At present,the nitridation of magnesium and its alloys is regarded as an effective surface treatment method to enhance corrosion resistance.To create durable nitrided layers on magnesium substrates with long-term stability,it is essential to thoroughly comprehend the influence of various techniques and processing conditions,as well as the resulting layer composition and microstructure.Additionally,a detailed understanding of how these fabricated layers behave in corrosive environments is crucial for optimizing their performance.This paper systematically reviews the research achievements and latest progress in the surface nitridation on magnesium alloys.The principles,advantages,drawbacks of different nitridation process,as well as their applications in enhancing the corrosion resistance of magnesium alloys are discussed.Furthermore,the paper summarizes the main technologies in the fabrication of magnesium nitride films,such as pulsed laser deposition,low-pressure chemical vapor deposition,reactive magnetron sputtering,thermal plasma synthesis,and molecular beam epitaxy,which offers a valuable reference for experimental research on magnesium nitride film.Finally,it also discusses the challenges and prospects of the research on the surface nitriding of magnesium and its alloys.
