Title: Method for preparing polymer surface to provide for later plating and improved metal plated plastic article produced by said method
Inventor: KENIISU POORU ZAANOCHI
IPC: C23C18/30
Filed: 1991-10-23
Abstract: PURPOSE: To disclose a new method which provides the surface of an arom. polymer with a metallic layer having a high adhesion property by chemically reforming this surface.  
     CONSTITUTION: The surface of the arom. polymer, such as polycarbonate, is nitrated by bringing the surface into contact with a nitrating soln., such as a mixture composed of nitric acid and sulfuric acid and is then hydroxylated by bringing the surface into contact with a hydroxylating soln., such as ammonium hydroxide. The surface hydroxylated in such a manner is chemically reformed and is made hydrophilic. The chemically reformed surface is subjected to electroless plating of a primary metallic layer. Next, a secondary metallic layer is applied on the primary metallic layer by electroless plating or electrolytic plating until the metallic layers of a desired thickness are obtd.

Title: Tip member of soldering iron
Inventor: SENOO JUNJI
IPC: B23K3/02
Filed: 1989-11-21
Abstract: PURPOSE:To perform safety operation without generating a short circuiting by contact with a peripheral circuit when an energizing electric circuit is soldered by forming a heat resistant insulating coated layer of a ceramic sintered compact on the peripheral surface of a soldering iron tip member. CONSTITUTION:The heat resistant insulating coated layer 6 of a ceramic sintered compact is formed on the peripheral surface of an iron part 3b other than a solder welding part 3a. Though this metallic coated layer 6, when it is formed, is heated to a high temperature in a soldering time, the iron tip member 3 can be prevented from deteriorating because oxide film is not formed though the surface of the iron tip member 3 reacts on oxygen in the atmosphere. Consequently, the heat resistant insulating coated part 6, together with the oxide film, can be prevented from peeling and the adhesion of the heat resistant insulating layer 6 to the iron tip member 3 is improved.
