Definitions
- This invention pertains to an improvement in the electrodeposition of bright zinc from aqueous, acid chloride plating baths. More specifically, this invention relates to the use of an additive which corrects a problem or condition encountered in plating baths using benzylidene acetone as a brightening agent.
- Benzylidene acetone is a very common and very important additive in acid chloride zinc electroplating baths. When used in combination with other ingredients it adds brightness to a very wide current-density range. But most distinctly, it adds a great deal of brightness and luster to very low current-density areas such as deep recesses and threads of bolts and screws.
- This oil stain is caused by an oil-like break-down product that is being formed in the plating bath through electrolysis. This oil cannot be removed by carbon treatment, zinc dust treatment, or filtration.
- the only method of overcoming the staining problem was to emulsify this oil by adding a suitable surfactant to the plating bath.
- the surfactants that are effective in this manner are high foamers and considerable problems are caused in an industrial plating operation. The foam can get so bad that it rolls right out of the plating tank onto the floor and over the equipment. Since the plating bath is corrosive to steel, it is very undesirable to let it come in contact with any expensive equipment.
- the present invention eliminates the oil staining and avoids the above mentioned problems. I have discovered that the careful addition of hydroxylamine or an acid salt of 'hydroxylamine to the plating bath removes this staining elfect immediately. The oil is converted to a nonollensive substance which either precipitates or is eventually removed by electrolysis. By using this corrective method, there is no troublesome foaming and no build up of harmful chemicals in the plating bath.
- This invention relates to the use of an additive comprised of from about 1 to to 100 to 1 parts by weight of hydroxylamine or an acid salt of hydroxylamine for eliminating oil-staining of electrodeposits obtained from aqueous, acid chloride, zinc electroplating baths containing benzylidene acetone as a brightening agent.
- the oxime remaining in solution is not detrimental and is probably removed eventually by electrolysis.
- EXAMPLE II Bath composition Concentration in gms./liter Zinc chloride 60 Ammonium chloride PH-T-O-O.
- the concentration of benzylacetone can conveniently be determined by conventional gas chromatographic techmques.
