Metals & Chemicals

Plating and anodizing chemicals include metal salts, anode materials, and other consumables for the electro deposition or electroplating of metal films. Electrodeposition is a process that deposits a metal at cathode from a solution of its ions. It places a substrate in a vessel of metallic salt solution and passes an electric current through the container. For electroplating application, plating and anodizing chemicals include the electrode that is to be plated, a plating anode to complete the circuit, an electrolyte that contains metal ions to be deposited, and a direct current source. Plating and anodizing chemicals and its supplies are used in electroplating, electroless plating, metal spraying, electrophoretic and vacuum metallization processes. Electroplating will place the substrate in a jug of metallic salt solution and passes a current through the container. Whereas electroless plating use a water-based reducing agent devoid of an external electrical source. ...

Anodising is the procedure by which the natural film on aluminium is very much increased in thickness. The metal is on the anodic side of the galvanic series. Its position is alike to zinc and magnesium, i.e. it is readily oxidised. This oxide on aluminium is physically corrosion resistant, abrasion resistant, very hard, an insulator and very tenacious. In its natural form the oxide film is less than 0.50 microns thick. Since the naturally occurring film is so thin and attached to a soft supple metal, it is easily damaged. So building up this coating will provide very useful properties for the aluminium anodising on Dallas. Preparation The very basis of every excellent coating is preparation. In anodising, good preparation is necessary. Oils and greases are removed in weak alkali solutions and the exterior is etched to remove heavy oxides. After rinsing, the aluminium metal is dipped into a desmut solution so as to remove the insoluble components of the aluminium which remains on t...

Plating and anodizing chemicals includes metal salts, formula additives, anode materials and other consumables for the electrodeposition or electroplating of the metal films or anodized layer formation. Electrodeposition is the process which deposits a metal at the cathode from the solution of its ions. Plating and anodizing chemicals include chrome stripper solutions, immersion plating solutions, as well as brush plating accessories and platinized titanium anode meshes. Whereas for electroplating applications, plating and anodizing chemicals these include the electrode to be plated, a plating anode to complete the circuit, an electrolyte that contains the metal ions to be deposited, and direct current power source. Anodizing chemicals and supplies are widely used in electroplating, electrophoretic, electroless plating, metal spraying, and vacuum metallization processes. Electroplating places the substrate in pot of metallic salt solution and pass an electric current through the co...

The practice of anodizing, or the controlled oxidation, of aluminum and its alloys are more than seven decades old. The main intention behind anodizing aluminum and its alloy parts is to guard the highly reactive surface against corrosion in aqueous environments, like moist air and sea water. Since the anodic coating could be produced in a range of colors, the painted parts are generally used in architectural applications. Further, as the process of aluminum anodization on CA would produce a hard ceramic covering, harder than that of the substrate from which it is formed, the anodic coatings are also used to shield aluminum parts from abrasions, especially sand abrasion. Traditional anodizing process is electrochemical oxidation. The part which is to be anodized is then connected to the positive terminal of a Direct Current (DC) power source and a non reactive metal, like stainless steel, is coupled to the negative terminal. The aluminum anode, and the stainless steel cathode are...
