PLATING ZINC METAL FINISHING

ZINC PLATING prevents oxidation of the protected metal by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not cause a breakdown of the substrate's surface integrity as it is formed. Indeed the zinc oxide, if undisturbed, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers. The majority of hardware parts are zinc plated, rather than cadmium plated.

 

ZINC PLATING CONSUMER PURPOSES


ZINC PLATING is the most common and economical type of plating.  Zinc, which has a distinctive bluish-white tint and a brilliant shine, is one of the most extensively used metals in the surface finishing industry. What makes it particularly popular commercially is its effectiveness and affordability as a form of plating. Zinc plating is also done in combination with other metals such as nickel, cobalt and tin. Zinc plating is most widely used commercially for plating iron and steel, but it is also used to protect finished products ranging from structural steelwork for buildings and bridges to nuts, bolts, screws, strips, sheets, wires and tubes.

ZINC PLATING GALVANIZATION

Zinc plating provides a soft and anti-corrosive covering around the substrate, preventing oxidation of the substrate (metal that is to be guarded) by forming a protective anti-corrosive barrier. Unlike other metal plating techniques it shields the object by acting as a sacrificial coating that prolongs the life of the underlying metal.
 

ZINC PLATING AUTOMOBILE INDUSTRY

Zinc plating technology has been used in the automotive industry for years in Japan, Europe and the United States. The auto industry uses zinc-nickel coatings for most of its products. The plated end products are used in passenger car and light truck power steering components, air conditioning, hydraulic brake components and for most under-the-hood components.

ZINC PLATING ELECTRICAL TRANSMISSION APPLICATIONS

Many zinc plating processes are used extensively in heavy electrical transmission components.  Metal parts or structures that are used in engineering products or for the purpose of providing linkages and anchorage are ideal candidates for zinc plating. Zinc Plating is used for nuts and bolts, ship anchors or cleats; in fact, any metal fixtures that spend the majority of their productive life in corrosive environments are ideal products to be Zinc Plated. Zinc plating on such objects gives additional protection by providing a highly resistant anti-corrosive film, thus increasing its longevity. Another popular use of zinc plating is in the coaxial TV cable connector, which is assembled within the aluminium hosing. These connectors are used indoors and outdoors. Alkaline zinc-nickel plating used in this type of application is also an environmentally safer substitute.

ZINC PLATING FASTENERS

Fasteners are another product that heavily depends on plating. Traditionally, cadmium has been used for plating, but it is not environmentally friendly and its anti-corrosion properties break down when exposed to heat. This has therefore given rise to zinc plating as a much better option. Plating fasteners in zinc-nickel plating is therefore now a fast growing industry.

ZINC PLATING FOR DEFENCE

Zinc plating is also found in manufacturing of tanks and armoured personnel carriers, with additional research being carried out in this area to find new avenues of its application.
