Definitions

  • the present invention relates to the electrodeposition of nickel and nickel alloys upon metals and non-conductors and has for its primary object to provide an improved electrolyte which is applicable with advantage to various forms of nickel plating by electro-deposition and is particularly suitable for use in producing the thick, hard and abrasion resistant coatings of nickel and nickel alloys required in eiectro-forming work; such as for example the production of the surfaces of pressure moulds by electro-deposition.
  • a nickel plating bath of the fluoride type posesses very good throwing power while plating a deposit with low stresses and we propose to use a bath of this kind in preference to other known types of nickel baths such as the Watts, Double salt, Formate and All Chloride types, as a basis for the invention hereinafter described.
  • wetting agents to avoid pitting in electro-plating is generally known but most of the known wetting agents increase the internal stresses of the electro-deposited coatings considerably. Moreover, they are known to decompose when submitted to the usual plating conditions, 1. e. when influenced by higher temperature, oxygen, development of hydrogen and associated factors and the products of the decomposition increase the stress still further, while the wetting qualities are at the same time lost.
  • the wetting agent as sold under the trade name Claytavon WM and formed of sulphonated cetyl and oleyl alcohols of which 40-70% is oleyl, and the rest cetyl alcohol serves well for this pur ose.
  • the hardness of the alloy deposited from the above bath is approximately 550 Vickers. This hardness of the electro-deposit shows relative stability even at temperatures between 300 and 500 C., i. e. at temperatures used in the production of zinc and aluminium pressure die-castings.
  • the addition of the two organic agents to the fluoride bath containing cobalt ensures hardness, stability at temperatures above 300 C., and the internal stresses, which are usually increased by wetting agents, can be substantially eliminated. An excessive cobalt deposition in the first plating period is prevented, and it is thus possible to build up a deposit of a relatively uniform nickel cobalt alloy.
  • the nickel electro-formed from the electrolyte of this invention is unusually stable in its hardness, even under the influence of relatively high temperatures and is not embrittled by submission to temperatures up to 300 C., a certain embrittlement sets in above 300 C., which may be mechanically disadvantageous.
  • cadmium to the electrolyte in concentrations such as l in 30,000 this embrittlement is prevented, while the cadmium addition leads to a gradual increase in ductility with the subjection of the metal to increasingly high temperatures, without.
  • the physical properties of the nickel referred to are not those ruling when the nickel is subjected to the temperatures mentioned but refers to properties of the nickel at room temperature, after having been heated to certain temperatures.
  • An electrolytic bath for the electrodeposition of nickel cobalt alloys upon non-conductors for electro-forming pressure molds consisting essentially in aqueous solution of 33-50 ozs. nickel sulphate, 1 to 3 on. cobalt sulphate, 4 to 6 ozs. boric acid, 1 to 2 on. sodium fluoride, V to 2 ozs. sodium chloride, 4 to 20 grams of 1-3-6 sodium naphthalene trisulphonate and 4 to 12 grams of sulphonated aliphatic alcohol per gallon of solution.
  • An elec'rolytic bath for the electron deposition of cobalt-nickel alloys upon metals and nonconductors in the production of pressure molds consisting essentially in aqueous solution for each gallon thereof 33 to ozs. of nickel sulphate, 4-6 ozs. of boric acid, 1 to 2 ozs. of sodium fluoride, 1 to 3 ozs. of cobalt sulphate, M4 to 2 ozs.
  • a process for producing the surface of a pressure mould of nickel cobalt alloy which consists of providing on a master of non-conducting material shaped in accordance with the articles to be moulded, a conducting surface, depositing nickel alloy on said conducting surface in an electrolytic bath consisting essentially in each gallon of aqueous solution of 33 to 50 ozs. of nickel sulphate, 4 to 6 ozs. of boric acid, 1 to 2 ozs. of sodium fluoride, l to 3 075. of cobalt sulphate, to 2 ozs.
  • a process for producing the surface of a pressure mould of nickel cobalt alloy which consists of providing on a master of non-conducting material shaped in accordance with the articles to be moulded, a conducting surface, depositing nickel alloy on said conducting surface in an electrolytic bath consisting essentially in each gallon of aqueous solution of 33 to 50 ozs. of nickel sulphate, 4 to 6 ozs. of boric acid, 1 to 2% ozs. of sodium fluoride, 1 to 3% ozs. of cobalt sulphate,
  • a process for producing the surface of a pressure mould of nickel cobalt alloy which consists of providing on a master of non-conducting material shaped in accordancewith the articles to be moulded, a conducting surface, depositing nickel alloy on said conducting surface in an electrolytic bath consisting essentially in each gallon of aqueous solution of 33 to 50 ozs. of nickel sulphate, 4 to 6 ozs. of boric acid, 1 to 2 ozs. of sodium fluoride, 1 to 3 /2 ozs. of cobalt sulphate, A, to 2 ozs.
