Abstract: A semi-conductor diode base consists of an outer layer of silver or copper, an intermediate sintered layer consisting of by weight (a) 40-70 parts silver powder with 60-30 parts graphite powder, or (b) 38-69 parts copper powder with 62-31 parts graphite powder and an overlying layer of silver or copper. In the preferred method the outer layers of silver or copper are also sintered but these layers may also be flame sprayed on to the sintered intermediate layer. Separate layers of the required powders of minus 325 mesh are placed in a die and compacted together at 10-40 tons p.s.i. and then sintered at 1500 DEG F. in a vacuum or neutral atmosphere. The sintered composite may then be coined at 20-40 tons p.s.i. Alternatively the powder layers may be hot pressed.
Abstract translation: 半导体二极管基座由银或铜的外层组成,中间烧结层由(a)40-70份银粉和60-30份石墨粉组成,或(b)38-69份铜 粉末与62-31份石墨粉末和银或铜的上覆层。 在优选的方法中,银或铜的外层也被烧结,但是这些层也可以被火焰喷涂到烧结的中间层上。 将所需的负325目粉末的各层放置在模具中并以10-40吨p.s.i一起压实在一起。 然后在真空或中性气氛中在1500°F下烧结。 然后烧结复合材料可以在20-40吨p.s.i。 或者粉末层可以被热压。
