Definitions
- Such baths contain the fluorocarbon resin particles in an amount of at least about 1 gram/ liter, and preferably in an amount of about 2 to grams/ liter.
- the fluorocarbon surfactant is desirably present in the bath in an amount of at least about 0.01 grams/ liter and preferably in an amount within the range of about 0.01 to 5 grams/ liter.
- Various fluorocarbon surfactants may be used so long as they are soluble in the plating baths and are not detrimental to the plating of the fluorocarbon resin particles and/or the metal. Examples of some of the fluorocarbon surfactants which may be used to obtain a dense codeposition of the resin particles with the metal are given in Table I.
- the fluorocarbon surface-active agents do not have detergent properties for the usual types of organic contamination (dust, traces of organic materials from vat linings, etc.) that may cause hydrogen gas bubbles to stick to the cathode, thus causing pitting in the cathode.
- the usual hydrocarbon surfactants for nickel plating such as sodium 2-ethyl hexyl sulfate, and sodium n-octyl sulfate to sodium lauryl sulfate, solubilize in their micelles the ordinary hydrocarbon type impurities, unlike the micelles of the fluorocarbon surfactants.
- the fluorocarbon surfactants are unique in their ability to Wet the fluorocarbon resin particles, and make possible the extensive codeposition of the dispersed fluorocarbon powders.
- the promoter addition agents for the acid copper plating baths are salts of monovalent cations such as those of thallium, cesium, rubidium, sodium, potassium, ammonium, lithium, amines, especially aliphatic polyamines or imines, such as tetraethylene pentamine, or amino acids such as alanine, or EDTA.
- the above brass bath yields about an 80-20 copperzinc brass alloy plate with the codeposited Teflon particles present.
- By using different ratios of copper to zinc it is possible to deposit higher zinc alloy brasses such as 70-30 and 60-40 copper-zinc brasses.
- the electroplating baths for the codeposition of the fiuorochemical resin particles should have relatively high cathode efficiencies, cathode efliciencies of at least about 90% being preferred. Additionally, however, electroless (electrodeless) copper or nickel or cobalt (or the alloys of the iron group) plating baths, which also incorporate fluorocarbon resin particles and the fluorocarbon surfactants, such as perfluoro p-ethyl cyclohexyl sulfonic acid or its salts, may also be used.
- Teflon particles and fluorocarbon sufactant as in Example I and the bath was operated at a temperature of from 170-180 F. to obtain a codeposit of Teflon particles and electroless nickel plate on a steel surface immersed therein.
- Acid gold baths operated at pH values from 3-6 may also be used instead of alkaline ones, for example:
- a method of electroplating which comprises codepositing dispersed fine fluorocarbon resin particles with a metal from an aqueous metal plating bath having cathode efficiencies higher than about and having dissolved in said plating bath a fluorocarbon surfactant in a concentration of at least about 0.01 gram/liter, and having at least 1 gram/liter of the fluorocarbon resin particles dispersed in the metal plating bath.
- fluorocarbon resin particles are essentially polytetrafluoroethylene of particle size less than about 50 microns.
- fluorocarbon surfactant is essentially perfluoro n-octyl sulfonic acid in a concentration of 0.01 to 1 gram/liter.
- fluorocarbon surfactant is perfluoro p-ethyl cyclohexyl sulfonic acid in a concentration of 0.05 to 2 grams/ liter.
- fluorocarbon resin particles are essentially polytetrafluoroethylene of particle size less than about 50 microns.
- a bath in accordance with claim 10 wherein said metal plating bath is essentially a lead-tin alloy electroplating bath.
