| Résumé : |
Vacuum metallization is the process of evaporating metals (most commonly aluminium) inside a vacuum chamber to achieve a uniform 'metallized layer". It is utilized for different applications In automotive industries, as a chrome alternative, for decorative metallic finishes, to create highly reflective coatings, heat shielding, and others. In this review paper concept of vacuum metallization on plastic components is reviewed on basic stages of vacuum metallization on plastic components i.e i) Pretreatment ii) metallization and iii) post-treatment The paper also consists of troubles faced during the vacuum coating of plastic and their remedies to overcome the tribulations. The vacuum deposition process is a physical, rather than electrochemical, method of depositing metals onto a substrate. The deposition takes place within a vacuum chamber where metal is melted and then becomes gaseous when it reaches its vapor point Gas molecules traveling by line of sight then condense on the desired substrate, creating a relatively uniform coating. The vacuum system itself consists ofan airtight chamber where the deposition process occurs. The plastic substrates that work well for vacuum metallization include ABS, polypropylene and styrene etc. |
