Abstract
In this paper, through the influence of baking temperature and time on the hydrogen release of silicon carbide particle reinforced aluminum matrix composite (SiCp/Al) base plate, titanium alloy enclosure and its package shell, the hydrogen control process of package shell is proposed. The results show that increasing the dehydrogenation temperature and prolonging the dehydrogenation time can reduce the hydrogen release from the package shell. By using this hydrogen control process, the internal hydrogen release of the package shell under the baking condition of 250℃ and 48 hours cannot be greater than 2000ppm, which can effectively improve the consistency of the hydrogen release of the product, and the impact on the appearance quality, adhesion and weldability of the coating is acceptable, meeting the product use requirements.
