“…A layer of the part is scanned according to CAD data, once the boundary of a layer is scanned the interior surface inside the layer is solidified. In this way layer by layer is solidified and part is produced (10). The company named Cubital Ltd evolved this technique in 1986. solid ground curing uses a photopolymer for the fabrication of parts.…”

Additive manufacturing is a new, rapidly emerging technique in the industrial sector. This is the process of creating parts by adding layer by layer material, hence it is called as 'Layer Manufacturing Process.’ This process is also called ‘Rapid Prototyping’ or ‘3DPrinting.’ This is a tool-less manufacturing method that produces parts in less time and with high precision. This process provides freedom for designing the parts and their complexity. Additive manufacturing has many advantages over conventional manufacturing processes like low production cost, no residual stresses, no wastage of material, etc. Nowadays, so much research work is going on in this additive manufacturing field. This manufacturing technology is going to replace the conventional manufacturing techniques in the upcoming days. In this paper, we discuss about the various additive manufacturing methods, its principles, applications, advantages, and challenges to industrial use.

“…For instance, using appropriate coatings and by corrective cooling of the tools can lead to an improved tool life. Different state of the art surface modification technologies to improve the performance of hot forming tools is presented by [19]. Studies have also been made to understand the high temperature tribological behaviour of different hot forming tool materials [20].…”

“…As implied in [3] it is important to accurately estimate the amount of material necessary for the machining of the tooling, which reduces the CO2 footprint of the tools. Besides, the forming tools used in hot forming experiences high tool wear, fatigue, and thermal loads compared to that of cold forming ultimately leading to a lower life time of the tools [19]. For instance, using appropriate coatings and by corrective cooling of the tools can lead to an improved tool life.…”

Increasing demands for reducing greenhouse gases drive the metal processing industries to a CO2-neutral production. A thorough understanding of CO2 emission sources from the stage of material acquisition up to the final component is thus necessary to improve the CO2 footprint of sheet metal hot forming process chains. To emphasize on this, an exemplary hot forming process chain is assessed to identify the impact of each sub-process step on total CO2 emissions and the savings potential of individual measures is evaluated. Moreover, a mathematical model is proposed that enables for the prediction of the product specific CO2 emissions as early as in the product design stage. This model is tested to calculate the CO2 emissions resulted during the production of an exemplary hot stamped sheet component. The results point out that the heating stage is responsible for the second highest percentage of CO2 emissions in the process chain next to the material acquisition. Thus, as one of the most suitable measures, a concept to recover process heat from hot formed components to the cold initial blanks is proposed and evaluated analytically.

“…Now We use lots of alloy powder for laser cladding in which Ni, Cr, Si, B Fe, Al, Ti, Co are commonly used for different determination (1)(2)(3). Different Researchers have applied different compositions of cladding powder and varied different laser cladding parameters and observed their effects on different mechanical properties i.e.…”

“…Loss in surface properties occurs due to corrosion, erosion, wear, etc. Wear is a distortion process of solid surface by eliminating surface material (1)(2). The presence of air alloys of metal gets oxidized at higher temperature, oxidation further developed at temperature is maybe the cause of corrosion occurrence (3).…”

Surface degradation due to hot corrosion and erosion in thermal power plants and gas turbines, is one of the primary concerns for many researchers, scientists and surface engineers. Hot corrosion is considered as a serious problem in coal-based thermal power plants which fulfill approximately 58.3% of the total electricity demand of India. The practice of using low-grade fuels at high functional temperatures is the overriding reason for accelerated hot corrosion. A case study stated that approximately 56% of boiler failures occur due to hot corrosion that may lead to reduced economical efficiency of the thermal power plants. Fortunately, this problem can be controlled by some preventive measures, and surface modification is one of the effective methods to enhance the lifespan of boiler components. Surface modification can be done through different surface coating processes like plasma spray, HVOF and D-gun etc. In this paper, we will discuss the effects of Laser cladding surface coating process to develop the corrosion resistance surface properties of different substrate materials
