Medieval Torture The garrote was the principal device used for capital punishment in Spain for one and a half centuries until its abolition. Originally, it entailed a mode of execution wherein a convict would be beaten to death with a club (garrote in Spanish).n this 15th-century depiction of the burning of Albigensians after an auto de fe, the condemned had been garroted previously. It is one of the first depictions of a garrote. Pedro Berruguete, Saint Dominic Presiding over an Auto-da-fe.

Why Metals Corrode? This is a very good question indeed! Corrosion is the disintegration of metal through an unintentional chemical or electrochemical action, starting at its surface. All metals exhibit a tendency to be oxidized, some more easily than others. A tabulation of the relative strength of this tendency is called the galvanic series.

Drinking Water Issues Corrosive Water (Lead, Copper, Aluminum, Zinc and More) Corrosion is a complex series of reactions between the water and metal surfaces and materials in which the water is stored or transported. The corrosion process is an oxidation/reduction reaction that returns refined or processed metal to their more stable ore state.n some cases, the water is so corrosive that the interior plumbing system needs to be changed and completely replaced with PVC piping, PEX, or other materials. Too bad, they did not test the water and install a neutralizing system before the piping corroded and caused leaks throughout the home.

Corrosion Corrosion is a natural process, which converts refined metal to their more stable oxide. It is the gradual destruction of materials (usually metals) by chemical reaction with their environment. In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen.ecause corrosion is a diffusion-controlled process, it occurs on exposed surfaces. As a result, methods to reduce the activity of the exposed surface, such as passivation and chromate conversion, can increase a material's corrosion resistance.

- Forging is the process by which metal is heated and is shaped by plastic deformation by suitably applying compressive force. Usually the compressive force is in the form of hammer blows using a power hammer or a press.Forging refines the grain structure and improves physical properties of the metal.With proper design, the grain flow can be oriented in the direction of principal stresses encountered in actual use.sually the compressive force is in the form of hammer blows using a power hammer or a press.

Galvanization A street lamp in Singapore showing the characteristic spangle of hot-dip galvanization. Galvanization (or galvanizing as it is most commonly called in that industry) is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc.

What is Galvanizing? Galvanization is the process by which zinc is coated over corrosive (easily rusted) metals. Galvanizing involves coating corrosive metals, such as steel and iron, with a non-corrosive metal.The process of galvanizing, not only protects from corrosion of various ‘soft metals’ but also adds strength of the original, uncoated metal. Electro-Galvanizing: It is an electrolytic process for galvanizing, where a thinner, tighter bonding coat of zinc is applied to a metal through “electroplating”. 2  Electro plating is a process of running a current of electricity through a saline/ zinc solution with a zinc anode and steel conductor.

corrosive Definition. Substance that causes visible discoloration, destruction, or irreversible changes, in living tissue at the point of contact within four hours. For the same effect on inanimate material, the term ' corroding ' may instead be used.

- Rusting is an example of a process called corrosion. Corrosion means that a chemical reaction has occurred in which metal atoms have combined with oxygen to form an oxide coat.When those metal atoms are iron, the corrosion is bad, because it corrodes quickly, weakening the original steel material.ust changes steel into a different material, one that is weaker than the original steel. Rusting is a big problem because so many things people use every day are made out of steel, like cars, trucks, bridges, roofs, holding tanks, machinery, nuts, and bolts.

Corrosion of Metals Corrosion is an oxidation reaction with atmospheric oxygen in the presence of water on the surface of a metal. Iron corrodes more quickly than most other transition metals to form an iron oxide. Corrosion or rusting of iron is accelerated in the presence of CO2 and also in the presence of salt solution. Rusting is oxidation because it involves iron gaining oxygen (Fe Fe2O3) or iron atoms losing electrons (Fe - 3e- Fe3+).

It was named in English via French from the name of Italian scientist Luigi Galvani.

Welding Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.as tungsten arc welding (GTAW), or tungsten inert gas (TIG) welding, is a manual welding process that uses a nonconsumable tungsten electrode, an inert or semi-inert gas mixture, and a separate filler material.

What is Corrosion? Corrosion is the deterioration of a metal as a result of chemical reactions between it and the surrounding environment. Both the type of metal and the environmental conditions, particularly gasses that are in contact with the metal, determine the form and rate of deterioration. All metals can corrode.

Corrosive Definition in Chemistry Corrosive Definition. Corrosive refers to a substance that has the power to cause irreversible damage or destroy another substance by contact. A corrosive substance may attack a wide variety of materials, but the term is usually applied to chemicals that can cause chemical burns upon contact with living tissue. A corrosive substance may be a solid, liquid, or gas. The term corrosive comes from the Latin verb corrodere, which means to gnaw.
