“…Material coating is a method of applying a thin layer of material on parent substrates in addition to enhancing their surface qualities [70][71][72]. Surface coating techniques, according to certain previous research publications, play a critical role in improving corrosion resistance qualities [73][74][75][76]. Surface coating is used to extend the life of several industrial products that regularly fail due to surface wear, including as gears, boiler surfaces, and bearings [77][78][79].…”

This article comprehensively reviews the causes of wear of hydraulic components used in hydro-static transmission systems and their remedies by thermal coating processes. The wear of critical components of the hydraulic pump and motors, hydraulic valves, etc., is mainly due to abrasion, erosion, and cavitation. The most commonly found modes of wear in hydraulic components are contamination and abrasion wear. Such wear arresting can be done by using the surface coating and texturing of materials over the wear zones of the damaged parts. This article discusses the causes of wear in hydraulic components and suggests various solutions to reduce such wear. Recent challenges associated with the proposed solution for wear arresting and future scopes are identified in this review. In the end, some novel techniques for the treatment of wear in hydraulic components, such as laser beam treatment, plasma, Tungsten inert gas arc, and Electric discharge coating, have been discussed, which is the potential future work for enhancing the useful life of hydraulic components. These surface treatment methodologies can be applied to alter the surfaces of crucial hydraulic components that experience considerable wear, as seen in hydraulic pumps, valves, and other elements such as hydraulic cylinders.

“…Inconel 625 (IN625) is a Ni‐based superalloy commonly used to manufacture high added value components due to its outstanding mechanical properties, at both cryogenic and high temperature, as well as its excellent resistance to different corrosive media, as reported by several authors such as Rombouts et al, [ 1 ] Hong et al, [ 2 ] Olakanmi et al, [ 3 ] and Abioye et al [ 4 ] For example, IN625 is used in the oil and gas sector for components subjected to high mechanical stresses in sea water, components exposed to flue gas, or flare stacks on offshore oil platforms. [ 5,6 ] Leyens and Beyer [ 7 ] also reported the applications of IN625 in the energy production industrial sector while Gasser et al [ 8 ] highlighted its application in the aerospace sector.…”

Nickel‐based superalloys are broadly used to produce high value added components in industrial sectors such as oil and gas, aerospace, energy production, etc. Additive manufacturing represents a viable alternative family of processes for near‐net shape fabrication. Herein, it presents results related to the toughness behavior of laser metal deposited Inconel 625 samples under impact tests, in the as‐deposited and post heat‐treated condition. Laser metal deposition is used to build Inconel 625 Charpy impact tests samples in two different orientations: vertical and horizontal. Half of the samples for each build orientation are subjected to annealing heat treatment whereas the remainder are kept as‐built. Distinct toughness behaviors are observed, with the vertical builds exhibiting a higher absorbed energy than the horizontal one. Furthermore, a decrease in absorbed energy after heat‐treatment is observed in the Charpy impact test results for both deposition orientation samples. A similar behavior is observed through Vickers microhardness measurements. However, in this case, although the horizontal deposited samples result always harder than the vertical ones, the heat treatment reduces the hardness difference between the two deposition directions. The obtained results highlight the influence of the manufacturing strategy on the toughness of the final components.

“…Inconel 625, a nickel-based non-magnetic super alloy consisting of nickel-chromium-molybdenum, has high corrosion resistance and excellent mechanical properties [7,8]. Chromium prevents corrosion by form-ing a layer of Cr2O3, and molybdenum provides resistance to crevice and pitting corrosion [9].…”

The Oil and gas exploration is one of the most strategic industrial sectors in the Brazilian economy. The discovery of deep water reserves adds more difficulty to the already problematic use of materials in equipment in extremely corrosive environments. With the objective of increasing the service life of the equipment, and consequently reducing the cost of maintenance and preventing against environmental catastrophes, it is common to use CRA claddings via welding processes, in which the nickel superalloy coatings stand out via the PTA welding process. In this context, the operation of internal cladding of risers becomes extremely complex due to the operational and metallurgical requirements imposed by the application. The present work aims at the development and empirical evaluation of the internal cladding procedure of risers with Nickelbased superalloy 625 via PTA welding process. From tests of cladding on plate, satisfactory preliminary parameters were reached for the performance of internal cladding tests on risers. From the adaptation of the welding parameters, comparative analyzes of three different procedures were carried out, with different weaving amplitude. Visual analysis and inspections were carried out via penetrating liquid and radiography, confirming the welding quality of all procedures performed. Still, proving the metallurgical quality of the developed procedures, analysis of chemical composition was carried out via EDX, presenting satisfactory results. Finally, a financial comparison of the process was elaborated, showing comparatively the consumption of powder and gas, and the time needed for internal cladding.
