一种镀铂的钛钯合金板及其制备方法
摘要：
本发明公开了属于耐腐蚀电极制备技术领域的一种镀铂的钛钯合金板及其制备方法。在钛钯合金板表面镀一层镍层后电镀铂层，钛钯合金板厚度为2～3mm，镍层厚度为1～1.5μm，铂镀层厚度为5～8μm。钛钯合金板经喷砂、除油和除氧化膜处理，除去表面油污和氧化膜，采用化学镀镍工艺镀镍，镀镍后放入清水中洗净，然后采用电镀铂工艺镀铂，镀铂后放入清水中洗净，置于有氩气保护的真空热处理炉中进行热处理。本发明的镀铂钛钯合金板铂镀层厚度为5～8μm，在钛钯合金板上电镀了一层厚铂层，钛钯合金板基体与铂镀层之间的结合力为22～28MPa，用扫描电镜观察表面状态，放大2500倍以上观察无针孔。
摘要（英）：

The invention discloses a platinum-plated titanium palladium alloy plate and a preparation method thereof, which belong to the technical field of preparation of corrosion resistant electrode. The preparation method comprises: plating a nickel layer on the surface of the titanium palladium alloy plate and plating platinum, wherein the thickness of the titanium palladium alloy plate is 2 to 3 millimeters, the thickness of the nickel layer is 1 to 1.5 micrometers, and the thickness of the platinum plating is 5 to 8 micrometers; and subjecting the titanium palladium alloy plate to sand blast, oil removal and oxide film removal treatment to remove oil stains and oxide films on surface, plating nickel by using a chemical nickel plating process, placing in clean water for washing after nickel plating, plating platinum by using a platinum plating process, placing in clean water for washing after platinum plating, and placing in a vacuum heat treatment furnace in protection of argon to perform heat treatment. In the invention, the thickness of the platinum plating of the platinum-plated titanium palladium alloy plate is 5 to 8 micrometers, a thick platinum layer is plated on the titanium palladium alloy plate, the bonding force between the titanium palladium alloy plate substrate and the platinum plating is 22 to 28MPa, the surface state is observed by a scanning electron microscope, and according to result of observation after amplification by 2,500 times, the platinum plating has no needle holes.
