Eswara Prasad and RJH Wanhill., Springer, Vol.1, p ,   Application of Zinc and Aluminium Coatings Zinc coatings can be applied by a range of techniques^ Sherardizing and hot dip galvanizing are diffusion-type coatings in which the zinc coating is metallurgically bonded to the steel by the iron-zinc alloys which form during the coating operation. Professor Julie Cairney studies materials using advanced microscopy techniques that can image matter down to atomic scale. Their microstructure can then be related to their properties, and this knowledge can be used to engineer advanced materials with desirable properties such as . Shielded Metal Arc Processes. The arc to the workpiece is made with a consumable electrode. There are several types of ion electrodes with alloying material either in the core of the wire, as a flux covering on the surface, or fed into the flame as a powder. It is used with cheap coatings and results in significant dilution. Open Arc Processes.

This structure and coating properties have long been accepted as typical of arc sprayed coatings. The demands of industry have currently exceeded the capabilities of some of these coatings however, the economic nature of arc spraying neccessitates further work in improving their properties.

Electric Arc Wire Spray With electric arc wire spray, an arc is formed by contact of two oppositely charged metallic wires, usually of the same composition. This leads to melting at the tip of the wire material. Air atomizes the melted spray material and accelerates onto the substrate.

The rate of spray is adjusted by appropriate. Thermally sprayed metal coatings can be applied in the shop or at site. No drying time is required, they do not sag or run, and can be applied to the required thickness in a single operation.

There is no limitation on the size of the workpiece that can be coated, as there is with hot-dip galvanizing, and since the steel surface remains cool.
