COATING SPECIALIST Alex Szokolik ith 32 years in the coatings industry‚ Alex Szokolik has earned the right to be called a coatings specialist. In 1991‚ he retired from his position at Esso Australia‚ where he was responsible for evaluating coatings for offshore and pipeline application‚ writing specifications‚ performing failure analysis‚ and conducting maintenance coating surveys to structure the company’s maintenance program. Since then‚ Szokolik has launched a new career as a consultant

Detailed Technical explanation: For selection of material of a centrifugal pump shaft‚ following criteria to be considered: i) Endurance Limit - as high as possible ii) Corrosion resistance - yes depends on fluid type and contact with shaft iii) Elongation - as low as possible The endurance limit is the stress below which the shaft will withstand an infinite number of stress reversals without failure. Since one stress reversal

Rust inhibitor that when added to liquids decreases the corrosion rates of a material. The researchers proposed for a rust inhibitor made of extract of squash seeds to prove if it is applicable as

entirely to rust and disintegrate. Surface rust is flaky and friable‚ and provides no protection to the underlying iron‚ unlike the formation of patina on copper surfaces. Rusting is the common term for corrosion of iron and its alloys‚ such as steel. Many other metals undergo equivalent corrosion‚ but the resulting oxides are not commonly called rust. Other forms of rust exist‚ like the result of reactions between iron and chloride in an environment deprived of oxygen – rebar used in underwater concrete

OBJECTIVE • To apply thin films of material to the surface of an object to change its external properties such as to increase corrosion protection‚ increase abrasion resistance‚ improve decorative quality or simply to deposit a layer which is part of a more complicated device. • MECHANICAL PROPERTIES: Mechanical properties of the electrodeposited film depend to a considerable

rapidly in moist conditions as compared to a dry environment such as a desert. Many other factors affect the rate of corrosion. For example the presence of salt greatly enhances the rusting of metals. This is due to the fact that the dissolved salt increases the conductivity of the aqueous solution formed at the surface of the metal and enhances the rate of electrochemical corrosion. This is one reason why iron or steel tend to corrode much more quickly when exposed to salt (such as that used to melt
