Published By | Publication Date | Number of Pages |
BSI | 2005 | 14 |
This British Standard specifies the methods of protection for magnesium and magnesium alloys and specifies the required characteristics for the performance of various protection schemes for magnesium, as well as the quality assurance of the coating obtained.
Two types of protection are produced:
- Type I: Chromating and BS X 38 primer and finish coat;
- Type II: Anodizing and unpigmented BS X 38 sealer and finish coat (optional)
This standard applies to parts in magnesium and magnesium alloys when used in aerospace construction, when reference is made to this standard.
