    摘要: Iron containing substrates are electrically polarized in a pre-plating composition containing one or more sulfonic acids and one or more grain refiners, the pre plating composition activates the surface of the steel substrate to receive thin tin or tin alloy. The thin tin or tin alloy is electroplated onto the activated surface of the steel substrate. The thin tinplate and alloy have reduced amounts of pores in the surface.

    摘要: Indium electroplating compositions containing 2-imidazolidinethione compounds electroplate substantially defect-free uniform layers which have a smooth surface morphology on metal layers. The indium electroplating compositions can be used to electroplate indium metal on metal layers of various substrates such as semiconductor wafers and as thermal interface materials.
