Gold plating metallized alumina ceramics
, 1978 Problems with gold plating a metallized ceramic part at the General Electric Neutron Devices Department led to a two-fold study. The first part of the study evaluated the production process and resulted in a temporary solution to the problems. The second in-depth part of the study evaluated methods for surface activation, the plating process and ...

Electroless Copper Plating on PZT Ceramics.
The Journal of Japan Institute for Interconnecting and Packaging Electronic Circuits, 1995 PZTセラミックスは, 圧電性を有するので, 圧力センサやレゾネータ, コンデンサなどの電子部品に利用されている。従来, PZTセラミックス上の電極や回路形成には, 導電性ペーストが利用されてきた。しかし, 電子部品の小型化に伴う微細回路の形成には, 導電性ペーストの適用が困難となってきた。それゆえ, PZTセラミックス上への無電解銅めっきの成膜について検討を行った。通常, セラミックスと無電解銅めっき間の密着性を得るためには, セラミックス表面を酸でエッチングする必要がある。しかし, PZTセラミックスの場合, エッチングを行うと本来持っている電気的特性が著しく低下するため, エッチングレスで無電解銅めっきを成膜する手法が求められている。そこで ...

Fabrication of a Plate-Type Porous Stainless Steel 316L Powder Filter with Different Pore Structures without Use of a Binder [PDF]
Archives of Metallurgy and MaterialsGenerally, when fabricating porous filters using metal powder, about 1 to 2 wt% of a binder is added to increase the formability of the metal powder. If the binder is not completely removed through a debinding and sintering process, however it can cause ...
