Materials and corrosion
The best way to prevent crevice corrosion is to prevent crevice corrosion is to prevent crevices. This can be done by using welds in place of bolts and rivets in joints. The design of various components should be done in such a way that there is always a drainage mechanism for the accumulating fluid so that the harmful corroding liquids do not come in contact with the metals for long duration of time. Other effective means of preventing crevice corrosion is the use of corrosion inhibitors and

Secondly, the reduction of the alkaline condition of the concrete around the steel creates the perfect condition for corrosion and pitting (Cadman 2012, para. The commonest route for this reduction of alkaline condition is carbonation of concrete, resulting in a neutral condition that supports corrosion.When compared to the impact of chloride environment on causation of corrosion, carbonation has a lower damage to the integrity of the reinforced concrete structure. This is because corrosion

Materials&Manufacturing Report Automotive Piston
The piston should also be designed with a material that is capable of handling the increased stress on the piston which increases due to the piston’s light weight. As the engine is switched on, the combustion process heats up the piston and rapidly expands its diameter. This expansion in diameter is likely to interfere with the engine’s operation in more ways than one. Given that the cylinder block that encloses the piston is usually designed to have a high heat capacity and is

However, plating the bars with chromium gives a challenge to users especially in terms of time and cost. Chromium takes about 500 minutes to treat a considerably shorter length of the bars, making it time consuming. Secondly, chromium is an expensive element making it difficult to acquire large quantities that would be sufficient in treating the bars for manufacturing hydraulic cylinder bars.Chromium plate bar is the best material for the manufacture of piston rod for hydraulic cylinder.

There are various kinds of steel and some of them can be explained as carbon steel, tools steel and alloy steel. Carbon steel is one that has carbon as its main component with no other element as an alloy. The amount of carbon in plain carbon steel ranges from 0.01% to 1. Of importance is the hardness and strength that steel gains from carbon. However, high carbon content leads to a reduction in the malleability and ductility of steel (Wadhawa & Dhaliwal, 2008).Tool steels is a king of a steel
