Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to chemical compounds large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide.
Electroless nickel plating is a process for depositing a nickel alloy from aqueous solutions onto a substrate without the use of electric current. It differs, therefore, from electro-plating which depends on an external source of direct current to reduce nickel ions in the electrolyte to nickel metal on the substrate.
The impregnation-precipitation method is used to prepare high surface area materials, commonly for battery anodes. A porous or highly textured conductive substrate is first impregnated by immersion in a nickel(II) salt solution. The substrate is then immersed in an alkaline solution to elicit the precipitation of Ni(OH) 2.
generated in the solution by the addition of ammonium or alkali metal hydroxides or carbonates. The time interval between additions of base solutions to an electroless nickel bath with a large PH is less critical than for a bath with a much smaller PH. A list of the commonly used buffers is given in Table 2.1. The
Lauric Acid is a saturated medium-chain fatty acid with a 12-carbon backbone. Lauric acid is found naturally in various plant and animal fats and oils, and is a major component of coconut oil and palm kernel oil.
Electroless nickel plating can provide a robust solution to corrosive attack across a range of corrosive mechanisms including galvanic corrosion, chemical attack and erosion. Electroless nickel plating (EN) can be applied to a wide range of basis metals including steel, copper, brass and aluminum alloys.
Electro nickel plating, also known as nickel electroplating or nickel electro-deposition, is becoming an increasingly popular process for a variety of different manufacturing applications. Electro nickel plating is a process that uses an electrical current to coat a conductive material, typically made of metal, with a thin layer of nickel.
Of Electroless Nickel Plating Glenn 0. Mallory The chemical deposition of a metal from an aqueous solution of a salt of said metal has an electrochemical mechanism, both oxidation and reduction (redox), reactions involving the transfer of electrons between reacting chemical species.
Workers who have been exposed to nickel on the job over an extended period of time can develop allergies, lung disorders, and cancer. Pregnancy and breast-feeding: Nickel is LIKELY SAFE in pregnant or breast -feeding adult women when taken by mouth in doses less than the tolerable upper intake level (UL) of 1 mg/day.
Sodium Sulphate increase in Nickel Plating Solution 2002. Q. We are a famous electroplater in karachi, Pakistan since long. We are doing Duplex Nickel Plating in our M.S. Parts. We have observed due to lack of knowledge about sodium Sulphate had been increasing in our Nickel Plating Solution.
In the electroless nickel-plating process, a nickel salt and hypophosphite solution serves as a bath for the base material. Various other chemicals present in the solution help control pH levels and stabilize the process. Once in the solution, the base material acts as a catalyst to the deposition of the nickel-phosphorous alloy onto the product.

- The advised optimum temperature for acid zinc potassium electroplating bath is 22 °C. Over 28 °C there are (commonly) problems of over-consumption of brighteners, under 15 °C there are problems to level, low conductivity and low solubility of potassium chloride and boric acid (addition of these may be troublesome).
Such solutions have utility in electroless nickel plating baths and processes as make-up solutions and replenishing solutions. The increased concentration of Ni cation results from the addition of the nickel salt of an alkyl sulfonic acid to the solution.
Packaging 50, 250 g in poly bottle Features and Benefits The vapor-phase co-reductions with other metal halides such as aluminum chloride (cat. no. 449598) by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resistance properties.
In these situations, the most common remedy is to activate the nickel prior to plating using an acid or acid salt. Ductility and stress. Poor ductility and high stress are primarily an indication of poor maintenance of the plating solution.
Intergranular cracking tendencies of fourteen stainless steels and two high-nickel alloys have been evaluated by exposing numerous specimens to polythionic acid and standard acid copper sulfate solutions.
Zinc Nickel plating therefore has become the corrosion resistant solution for automotive components to protect against these environments. Zinc-nickel has received increasing commercial acceptance, over the past 20 years.
Nickel dibutyldithiocarbamate uses and applications include: UV stabilizer, antioxidant, antiozonant, accelerator, peptizing agent for synthetic rubbers, polyolefins; heat-aging inhibitor for neoprenechlorosulfonated polyethylene
These changes can also be categorized on the basis of salt gets formed or not or if it is that the heat gets evolved or not. While talking about the acids or bases, the products that get formed can be illustrated in following ways if we look by the ways of chemistry. How Do Both Acids and Bases React with Metals 1. When Acid Mixes Up With a Metal:-

Salt spray testing is widely regarded as the most reliable method for measuring the effectiveness of an anti-corrosive coating. In simple terms, salt spray testing entails the steady application of a salt water solution to a coated material to assess how long it takes for rust to appear on the surface.
Controlling Electroless Nickel Baths. To prevent the effects of nitric acid contamination, it is good practice to use a final rinse of sulfamic acid in the EN tank prior to making up a new solution. Use nitrate test papers to confirm the cleanliness of rinse tank and filtration systems before mixing a new EN solution.
