Platinum coatings are prepared by electroplating platinum on the surface of rare metals. Both alkaline baths and acid baths are employed as the solution system, and main salts include different water-soluble platinum complexes of ammine, hydroxide, chloride and sulfate. The platinum coatings so obtained on rare metals are applied to water disposal, chemical technology, metallurgy, electronic technology, etc.%采用电镀的方法在稀有金属钛、钽、铌、钼表面制备铂涂层。镀铂体系主要有碱性和酸性溶液，镀液主化合物是P盐、羟基络合物、氨(胺)络合物、氯络合物、硫酸盐等。稀有金属镀铂电极主要应用于水处理、化工、冶金、电子行业等领域。
