摘要： The composition disclosed is an improved black chromium plating bath useful, for example, for solar selective coatings. The bath comprises an aqueous solution of sulphate-free chromic acid containing nitrate, borate and fluorosilicate ions. Such a bath can be employed at room temperature or higher, e.g. in the temperature range 30 DEG C to 50 DEG C, and at a low current density, e.g. 0.07 to 0.28 A/cm , to obtain a good quality black chromium deposit, which is quite coherent and has a high absorptivity to emissivity ratio, e.g. about 8.

摘要： Provided is a steel sheet for cans that has an excellent surface appearance. Also provided is a production method for the steel sheet for cans. The steel sheet for cans has, on the surface thereof, in order from the steel sheet side, a chromium metal layer and a hydrous chromium oxide layer. The chromium metal layer is deposited in an amount of 65-200 mg/m 2 , and the hydrous chromium oxide layer is deposited in an amount of 3-15 mg/m 2 in terms of chromium. The chromium metal layer includes: a flat chromium metal layer that has a thickness of at least 7 nm; and a granular chromium metal layer that includes granular protrusions that are formed on the surface of the flat chromium metal layer. The maximum grain size of the granular protrusions is 100 nm or smaller. The number density of the granular protrusions per unit area is 10/µm 2 or higher.

摘要： The present invention relates to a surface-treated copper foil for a PCB having a fine-circuit pattern and a method of manufacturing the same. The method of manufacturing the surface-treated copper foil for the PCB having the fine-circuit pattern according to the present invention includes a first step of disposing a copper foil as an anode in a plating solution including one or more metallic ions of Co, Ni, Mo, W, Cu, and Fe and forming a metal alloy layer by electrolysis, a second step of forming a roughened layer with a protrusion by roughening the formed metal alloy layer, a third step of forming a Zn coating layer on the roughened layer, a fourth step of forming an electrolytic chromate layer on the coating layer, and a fifth step of forming a silane coupling agent-treated layer on the electrolytic chromate layer.
According to the present invention, the copper foil is surface-treated by forming the metal alloy layer to improve peel strength of the copper foil.摘要翻译： 本发明涉及一种表面处理铜箔用于具有微细电路图案及其制造的方法的PCB。 制造表面处理铜箔具有雅丁微细电路图案对本发明的印刷电路板的方法包括：设置一铜箔作为在电镀液中的阳极包含CO，Ni中的一种或多种金属离子的第一步骤 ,,铜，钼，W，Fe和形成通过电解的金属合金层，通过粗糙化所形成的金属合金层，粗糙化层上形成Zn系镀层的第三步骤形成具有突起的粗糙层的第二步骤 ，在涂布层上电解铬酸盐层的形成的第四步骤，和在形成电解铬酸盐层上形成硅烷偶联剂处理层的第五步骤。 。根据本发明，将铜箔进行表面处理，通过形成金属合金层，以改善铜箔的剥离强度。
