“…The addition of heat treatment process on the CoNiFe nanocrystalline coating also effectively reduced the surface roughness compared to the other 30 minutes CoNiFe nanocrystalline coating. Similar improvement of surface roughness was discovered by Bejaxhin et al [25]. They observed an increase in hardness value due to the heat treatment effect.…”

Coatings are frequently used to enhance the mechanical and physical characteristics of mild steel by protecting mild steel surfaces against corrosion. Corrosion might attack surface without proper coating method which may lead to structural failures and increase maintenance cost. The main objective of this study is to investigate the effect of CoNiFe nanocrystalline coating on surface roughness, hardness, and tensile performance of mild steel substrate. Different parameters were introduced, such as current, pH, deposition times and heat treatment to analyse surface roughness, hardness, and tensile strength of CoNiFe nanocrystalline coating. The lowest surface roughness of 2.14 µm was recorded by CoNiFe nanocrystalline coating with 30 minutes deposition time at pH 3, I: 3 A and heat treated, while the highest recorded surface roughness of 4.233 µm was detected on uncoated mild steel. The highest improvement of microhardness was observed on CoNiFe nanocrystalline coating with 45 minutes deposition time at pH 3, I: 1.5 A and heat treated (393.6 Hv) as compared to the uncoated mild steel (171.44 Hv). Tensile performance of CoNiFe nanocrystalline coating with 45 minutes deposition time at pH 3, I: 1.5 A and heat treated was the highest with yield stress and ultimate tensile stress of 472.35 MPa and 559.11 MPa, respectively. The lowest tensile performance was recorded by uncoated mild steel with yield stress and ultimate tensile stress of 149.40 MPa and 186.78 MPa, respectively.CoNiFe nanocrystalline coating has considerably improved the mild steel surface roughness, hardness and tensile strength which indicate superior mechanical properties for future engineering application.

“…Due to this reason, the inserts start to get blunt as a built-up edge is formed on the cutting edge of the insert; hence, it also increases the surface roughness. A similar pattern of surface roughness on steel [64,65] and on similar material has been reported earlier as well [8,13,66]. In addition to this, the higher cutting forces are also responsible for the higher surface roughness, and increasing the cutting speed increases the amount of cutting forces [67].…”

“…Due to the decreasing cutting forces, less elastoplastic deformation takes place, leading to improved surface roughness [43]. The reduction in SCE with the increase in the depth of cut is an indicator that the cutting forces are also reduced, and hence, a better surface finish is achieved with the increase in the depth of cut for this design of experiment [66]. The increase in the number of inserts increases the number of passes on the workpiece [71], and the vibrations are also increased.…”

Due to the increasing demand for higher production rates in the manufacturing sector, there is a need to manufacture finished or near-finished parts. Burrs and surface roughness are the two most important indicators of the surface quality of any machined parts. In addition to this, there is a constant need to reduce energy consumption during the machining operation in order to reduce the carbon footprint. Milling is one of the most extensively used cutting processes in the manufacturing industry. This research was conducted to investigate the effect of machining parameters on surface roughness, burr width, and specific energy consumption. In the present research, the machining parameters were varied using the Taguchi L9 array design of experiments, and their influence on the response parameters, including specific cutting energy, surface finish, and burr width, was ascertained. The response trends of burr width, energy consumption, and surface roughness with respect to the input parameters were analyzed using the main effect plots. Analysis of variance indicated that the cutting speed has contribution ratios of 55% and 47.98% of the specific cutting energy and burr width on the down-milling side, respectively. On the other hand, the number of inserts was found to be the influential member, with contribution ratios of 68.74% and 35% of the surface roughness and burr width on the up-milling side. The validation of the current design of the experiments was carried out using confirmatory tests in the best and worst conditions of the output parameters.

“…The grain sizes of various welded portions made of the alloy AA6061-T6 were examined by [18] Ghiasvand et al (2020). The wear and tribological properties can be easily carried out with the optimization and simulations by [19] Bejaxhin et al (2021). In this inquiry, friction stir welding is performed, and finite element simulation is used to investigate the various friction stir welding parameters.…”

Consuming various TIG welding settings, the impact of mechanical properties on the butt joint of 410-Martensitic Stainless Steel Plate is explored. Mechanical properties such as tensile strength and hardness are evaluated on the welded butt junction plates using three levels of 200 A, 220 A and 240 A welding currents and the electrode diameters of 1.5, 2 and 2.5 mm and four factor parameters of inputs. Welding current, wire feed rate, electrode diameter, and gas flow rate are set as input parameters. The optimal input responses of welding current, electrode diameter, wire feed rate, and gas flow rate are employed over the 27 sample specimens based on array L27 Design of Experiment tool. The input parameters 240 A of welding current have improved significantly over the structural changes on martensitic form which is evidenced by their multiple SEM Micrographs, as it can be seen in the Hardness up to maximum of 512 BHN and the Tensile strength of 1090 N/mm 2 outcomes.
