defined as the destructive and unintentional attack of a metal; it is electrochemical and ordinarily begins at the surface.

Corrosion

form of electrochemical corrosion that occurs with equivalent intensity over the entire exposed surface and often leaves behind a scale or deposits.

Uniform Attack

occurs when two metals or alloys having different compositions are electrically coupled while exposed to an electrolyte.

Galvanic Corrosion

Electrochemical corrosion may also occur as a consequences of concentration differences of ions or dissolved gases in the electrolyte solution, and between two regions of the same metal piece.

Crevice Corrosion

another form of every localized corrosion attack in which small pits or holes form.

Pitting

occurs preferentially along grain boundaries for some alloys and in specific environments.

Intergranular Corrosion

found in solid solution alloys and occurs when one element or constituent is preferably removed as a consequence of corrosion processes.

Selective Leaching

arises from the combined action of chemical attack and mechanical abrasion or wear as a consequence of fluid motion.

Erosion-Corrosion

fresh coat of paint will enhance the appearance of your metal structure and prevent corrosion.

Protective Coating

Applying a powder coat is another effective method of corrosion prevention.

Protective Coating

Theoretically, plating is almost similar to painting. Instead of paint, a thin layer of metal is applied to the metal you want to protect.

Metal Plating

are chemicals applied to the surface of the metal that react with the metal or the surrounding gases to inhibit or suppress the electrochemical processes that lead to corrosion.

Corrosion inhibitors

a coat of a metal that is likely to oxidize is added on the surface of the metal you want to protect.

Sacrificial coatings

The environment plays a significant role in the corrosion process. By controlling the environment, you can prevent or reduce the rate of corrosion.

Environmental Measures

Designing with corrosion in mind can help inhibit the process and prolong the life of the metal.

Modifying the design

is a testing and analysis technique used by industry to evaluate the properties of a material, component, structure or system for characteristic differences or welding defects and discontinuities without causing damage to the original part.

Non-Destructive Testing

comprises a range of non-destructive testing (NDT) techniques that send ultrasonic waves through an object or material.

Ultrasonic testing (UT)

is used to detect surface cracks or flaws in ferromagnetic (easily magnetized) materials, such as steel, nickel, cobalt, iron and their alloys.

Magnetic Particle Testing

is a non-destructive testing (NDT) method which uses either x-rays or gamma rays to examine the internal structure of manufactured components identifying any flaws or defects.

Radiographic Testing (RT)

refer to any metal that contains iron.

Ferrous metals

don’t contain iron.

Non-ferrous metals

are generally made by taking mixtures of clay, earthen elements, powders, and water and shaping them into desired forms.

Ceramic

is an inorganic non-metallic solid made up of either metal or non-metal compounds that have been shaped and then hardened by heating to high temperatures.

Ceramic

is any of the various hard, brittle, heat-resistant and corrosion-resistant materials made by shaping and then firing a nonmetallic mineral, such as clay, at a high temperature.

Ceramic

is a substance or material consisting of very large molecules, or macromolecules, composed of many repeating subunits.

Polymer

include silk, rubber, cellulose, wool, amber, keratin, collagen, starch, DNA, and shellac.

Natural polymers (also called biopolymers)

include PVC (polyvinyl chloride), polystyrene, synthetic rubber, silicone, polyethylene, neoprene, and nylon.

Synthetic polymers

any of a class of natural or synthetic substances composed of very large molecules, called

Macro-molecules

that are multiples of simpler chemical units called

Monomers

play a crucial role in living things, providing basic structural materials and participating in vital life processes.

Organic polymers

is a polysaccharide, a polymer that is composed of sugar molecules.

Cellulose

consists of a complicated three-dimensional network of polymers.

Lignin

are polymers of a simple hydrocarbon, isoprene. Another familiar isoprene polymer is rubber.

Wood resins

are materials that consist of molecules formed by long chains of repeating units. They may be natural or synthetic.

Polymers

The classification of thermoplastics and thermosets is based on their response to heat.

Thermoplastic Polymers

Thermosets are typically heated during initial processing, after which they become permanently hard.

Thermosetting Polymers

are highly elastic polymers with mechanical properties similar to rubber.

Elastomers

A thin layer of metal like chromium or nickel is deposited in the substrate metal in an electrolyte bath.

Electroplating

It involves cold welding a metal powder to the substrate material.

Mechanical plating

This method uses a chemical reaction to deposit a coating of metal like nickel or cobalt to the primary metal.

Electroless

It's a simple coating technique that requires the substrate to be immersed in a molten bath of protective metal, forming a thin protective layer around the substrate metal.
