Immersion zinc plating is an electroless (non-electrolytic) coating process that deposits a thin layer of zinc on a less electronegative metal, by immersion in a solution containing a zinc or zincate ions, Zn(OH) 2− 4. A typical use is plating aluminum with zinc prior to electrolytic or electroless nickel plating.
Sayerlack was established in 1954 in Bologna for the purposes of producing coatings to finish, protect and ennoble wood, with particular emphasis on furniture, accessories for furniture and fittings. In 1958, the first R&D centre opened, and in 1988, the first waterborne coatings were created, representing an innovative product for the industry.
The chosen content of zinc depends on the required productivity and part configuration. High zinc improves the bath's efficiency (plating speed), while lower levels improve the bath's ability to throw into low current densities. Typically, the Zn metal level varies between 20 and 50 g/L (2.7-6.7 oz/gal). The pH varies between 4.8 and 5.8 units.
Zinc flake coating is a generic term for the coating technology and this is marketed by the different suppliers under their respective brand names. The companies such as SBILLP , ASAMA GIKEN , Anocote , Cadon , Sundram , generally act as licensors for the individual coating businesses.
Chromate conversion coating or alodine coating is a type of conversion coating used to passivate steel, aluminium, zinc, cadmium, copper, silver, titanium, magnesium, and tin alloys. [ 1 ] : p.1265 [ 2 ] The coating serves as a corrosion inhibitor , as a primer to improve the adherence of paints and adhesives , [ 2 ] as a decorative finish, or ...
Mechanical plating, also known as peen plating, mechanical deposition, or impact plating, is a plating process that imparts the coating by cold welding fine metal particles to a workpiece. Mechanical galvanization is the same process, but applies to coatings that are thicker than 0.001 in (0.025 mm). [ 1 ]
Megan Kate Gale (born 7 August 1975) is an Australian model and actress. [1] Born in Perth, Western Australia, Gale won a model contest when she was 18 in her home town. In 1999 she was cast in a series of commercials for the Italian branch of telecommunications company Vodafone. This led to wide exposure in both Italy and her homeland ...
In comparison to a zinc (galvanized) coating galvannealed has better spot weldability, and is paintable, [4] Due to iron present in the surface alloy phase galvanneal develops a reddish patina in moist environments - it is generally used painted. [5] Zinc phosphate coating is a common pre-painting surface treatment. [4]
