TL;DR: In this paper, an electroless nickel plating film was formed on an electrode pattern formed on the surface of a substrate such as of ceramic by baking, etc, of silver or palladium-containing silver through electroless Nickel plating.
Abstract: PURPOSE:To form an excellent electroless nickel plating film only on an electrode pattern formed on the surface of a substrate such as of ceramic by baking, etc, of silver or palladium-containing silver through electroless nickel plating CONSTITUTION:Silver or palladium-containing silver paste is applied to a substrate surface at a silver-pattern printing step 2, and baked at a baking step 3 to form an electrode pattern, the electrode pattern is treated with an acidic liquid at an acidic-liquid treating step 6 and treated with a reducing liquid at a reducing-liquid treating step 8, and an electroless nickel plating film of a uniform thickness is formed onto the electrode pattern at an electroless nickel plating step 9

TL;DR: In this paper, a method for manufacturing powder metallurgy of a helical gear with improved high hardness, wear resistance, lubricating properties, and corrosion resistance in order to be used as a deceleration gear whose rotation number is few but a compressive force is high is presented.
Abstract: The present invention relates to a method for manufacturing powder metallurgy of a helical gear capable of manufacturing a helical gear with powder metallurgy with improved high hardness, wear resistance, lubricating properties, and corrosion resistance in order to be used as a deceleration gear whose rotation number is few but a compressive force is high. Moreover, the method for manufacturing powder metallurgy of a helical gear which is a cylindrical gear for transmitting rotary motion between two parallel shafts, and wherein a teeth of the gear is inclined to one side comprises: a powder mixing step for forming metal powder by mixing an additive including 4.5-5.5 wt% of nickel (Ni), 2.7-3.3 wt% of copper (Cu), 0.7-0.9 wt% of molybdenum (Mo), 0.3-0.5 wt% of manganese (Mn), 0.1-0.3 wt% of silicon (Si), 1.3-1.7 wt% of carbon, and 0.3-0.7 wt% of a lubricant, and a main raw material of other residual iron (Fe); a powder forming step for pressing and forming after inserting the metal powder into a mold having a cavity coupled with the helical gear; a powder sintering step for applying heat to the powder pressed and formed in the form of the helical gear by the mold at a certain temperature for a certain time; a post processing step of post processing a sintered body wherein powder is sintered; and an electroless nickel plating step for electroless nickel plating the surface of the sintered body post processed.

TL;DR: In this paper, a pole plate material of a super-capacitor is used to make a silicon micro-channel, which is then used as a substrate for the micro-electro-mechanical system silicon process.
Abstract: The invention relates to a pole plate material of a super-capacitor, and a preparation method thereof, which are based on the micro-electro-mechanical-system silicon process and belong to the filed of capacitor manufacturing. In the pole plate material of the super-capacitor, a nickel protoxide thin film is wrapped on a silicon micro-channel substrate layer. The preparation method of the material comprises the following steps: an electrochemistry method is used for making a silicon micro-channel which is then taken as a substrate; after surface pretreatment is finished, a nickel layer is deposited in an electroless nickel plating solution; finally, fast thermal annealing is carried out in the atmosphere of oxygen; and nickel protoxide/silicon micro-channel compound material is formed. The pole plate material of the super-capacitor has large specific area and high chemical activity, is beneficial for electrolyte to be in better contact with active materials and can obtain relatively high charge storage capability and better capacitance characteristic; in addition, the combination of the pole plate material with the current micro-electronic processing technique can cause the super-capacitor to be easier for miniaturization and integration.
