摘要： An electrolyte for use in electrolytic platinum platinum plating that results in reduced Cl, S, or P contaminant production. The bath comprises 0.01 to 320 g/lit of platinum in the form of the platinum salt dinitrodiammine platinum, Pt(NH3)2(NO2)2 or variants thereof and 0.1 to 240 g/lit of alkali metal carbonate M2CO3 or bicarbonate MHCO3 where M is selected from a group comprising lithium (Li), sodium (Na), potassium (K), rubidium (Rb) and cesium (Cs).

摘要： A wear-resistant electrode tip for a spark plug, and a spark plug which incorporates the wear-resistant tip. The wear-resistant tip includes an alloy of platinum, iridium, and tungsten. Surprisingly, by addition of a small amount of tungsten to platinum-iridium alloy, the wear-resistance of a resultant spark plug is greatly improved. The spark plug electrode tip according to the invention is either spherical or rivet-shaped. During manufacture, the spark plug electrode tip is annealed in an annealing furnace. The annealing furnace is preferably either charged with an inert gas such as argon or nitrogen, or is subjected to a vacuum. The electrode tip is, optionally, further externally coated with platinum or a compatible bonding metal alloy before attachment to the electrode. Subsequent to annealing and, where used, to external coating, the spark plug electrode tip is placed in a welding fixture. The tip is then aligned with a spark plug electrode and is resistance welded thereto. Similar procedures are preferably performed on both the center and side electrodes of the spark plug. The annealed spark plug electrode tips using the novel alloys according to the invention have a high resistance to attack by lead and other corrosive elements typically present in the combustion chambers of internal combustion engines. A preferred method of making a wear-resistant spark plug is also disclosed.

The bath comprises 0.01 to 320 g/lit of platinum in the form of the platinum salt dinitrodiammine platinum, Pt(NH3)2(NO2)2 or variants thereof and 0.1 to 240 g/lit of alkali metal carbonate M2CO3 or bicarbonate MHCO3 where M is selected from a group comprising lithium (Li), sodium (Na), potassium (K), rubidium (Rb) and cesium (Cs). A method of improving oxidation resistance of a platinum modified aluminide diffusion coating on a substrate, comprises electroplating the substrate using this electrolyte and then aluminizing the electroplated substrate at an elevated temperature to grow a platinum modified aluminide diffusion coating.
