Types of Corrosion in General

 1 Galvanic Corrosion  Galvanic corrosion is also known as bimetallic corrosion, as the name suggests two different types of metal, when two dissimilar metals kept together directly or indirectly, in one of the metals corrosion rate occurs at a faster pace and the other metal remains unaffected. There is basically a galvanic couple that forms … Read more

Sensitization in Steels and other metals

Sensitization  Sensitization is a term used to describe the precipitation of carbides at the grain boundaries of metals or alloys generally during high-temperature exposure. In most cases, carbides are formed due to depleted levels of chromium and other corrosion resistance elements and, because of this steel is in danger of intergranular corrosion (IGC) or intergranular … Read more

Electrochemical testing for Corrosion

The condition of corrosion in a concrete or metal element is determined through electrochemical corrosion testing. Electrochemical corrosion testing, which is based on electrochemical theory, evaluates corrosion damage and, when possible, determines corrosion rates. All corrosion is an electrochemical reaction involving oxidation and reduction. To assess the corrosion characteristics of metals and metal components in … Read more

Wire cut EDM vs Conventional EDM

  Working Principle of Electrical Discharge Machining  EDM (Electrical Discharge Machining) is a method through which metal is removed by using an electrical spark, the temperature at which this removal happens is around 8000 to 12000 degrees Celsius. In this process, spark always takes place in the dielectric of deionized water. In this distilled water … Read more

Industrial applications of AISI 316L

  Introduction  In AISI 316L the “L” stands for “low carbon” content. The carbon quantity present in AISI 316L stainless steel must be ≤ 0.03. and in AISI 316 it must be ≤ 0.07. AISI 316L is a widely used steel and applications varying from medical devices to military equipments. This is actually the second most common stainless steel after … Read more

Wire Arc Additive Manufacturing (WAAM)

  Wire Arc Additive Manufacturing (WAAM)  The invention of wire arc-additive manufacturing (WAAM) is driven by the demand for better manufacturing efficiency in engineering constructions, presently called a direct energy repositioning arc (DED-arc). Its ability to produce very close to the net form provides the potential for significant cost and lead times reductions without needing … Read more

A Review Study on 4D Printing and Materials

Introduction 3D printing, also known as “Additive Manufacturing,” is a technique for converting digital designs into actual products by layering them together. On this technology, 4D printing is built. With one major exception: it makes use of unique materials and complex patterns that are “programmed” to cause your 3D print to alter shape. In essence, … Read more

Magnetic Field Assisted Super-Finishing Process

Introduction  A surface finish is a surface finish technique used to drive abrasive particles onto the target surface using magnetic field supports, sometimes called a magnetic abrasive finish. As such, it is feasible to finish the surfaces which have been traditionally unreachable (e.g. within a long, curved pipe). A variety of methods have been developed … Read more

What is Mechanical Engineering and some of the Research Areas

An Introduction to Mechanical Engineering  The study, design, development, construction, and testing of mechanical and thermal sensors and devices, such as tools, engines, and machines, is known as mechanical engineering. The introduction of the steam engine, automated production, and the demands of train transportation necessitated increasingly imaginative and sophisticated technical solutions during the industrial revolution.  … Read more

Applications of 3D Printing

3D printing techniques are finally reaching their full potential and are now being employed in the manufacturing and medical industries and sociocultural sectors that promote commercial 3D printing. In the previous decade, there has been a lot of buzz about the possibilities that can be realized by using 3D printing as one of the primary … Read more
