“…In line with this result obtained, the highest corrosion resistance was determined at the highest reduction ratio. Liu et al [26] stated that poor surface roughness reduces corrosion resistance by increasing surface defects and expands the effective surface area involved in the corrosion process. They also stated that plastic deformation can lead to the formation of an oxide film on the surface more easily and more stable by activating a surface electrochemically.…”

This study was carried out in order to reveal the effect of reduction ratio, one of the parameters of the skin-pass rolling manufacturing process of sheet metal materials, on the corrosion behaviours. In this experimental study, AISI 304 stainless steel sheet material samples were subjected to skin-pass rolling process with different reduction ratios (0.5%, 2.0%, 4.2% and 7.2%). The corrosion behaviours of skin-pass rolled AISI 304 stainless steel sheet material samples in 3.5% chloride solution was determined by potentiodynamic polarization curves. The changes in the surfaces were evaluated together with the surface roughness measurements and microstructure images. It was concluded that the increase in skin-pass rolling reduction ratio increased the corrosion resistance. The arithmetic mean roughness (Ra) did not give sufficient results to prove the finding that corrosion resistance improves as the reduction increases. The change of valleys and peaks in the roughness profile of the skin-pass rolled samples before and after corrosion was found to be evidence that the increase in reduction ratio improves corrosion resistance. As the skin-pass rolling reduction ratio increased was determined in the microstructural images that the amount of oxide layer increased and this situation was clarified from X-ray spectroscopy (EDS) findings. Electrochemical measurements, surface roughness profiles, microstructure images and EDS analyses were obtained with results that support each other.

“…The pursuit of materials with high strength-to-weight ratio and corrosion resistance has prompted researchers to conduct extensive studies on stainless steel [1]. 321 steel in addition to resistance to oxidizing acid corrosion, because it contains Mo, Cu, and other elements are also resistant to sulfuric acid, phosphoric acid, as well as formic acid, acetic acid, urea, and other corrosion [2].…”

321 stainless steel has high room temperature strength and oxidation resistance. It is investigated that the corrosion resistance of 321 stainless steel in hydrochloric acid solutions containing different concentrations of NaCl in the research. The alloy is mainly composed of austenitic stainless steel. The results of electrochemical tests were analyzed, and it was confirmed that NaCl could promote the corrosion of 321 stainless steel, but the corrosion would be suppressed to a certain extent when the NaCl concentration reached 0.10 mol/L. The research results can provide a reference for the corrosion resistance improvement research of 321 stainless steel.

“…This material offers high toughness, resilient strength with high ductility and thermal conductivity. Moreover, it requires high cutting force to machine; while processing it especially at higher speed and feed rate leads to excessive tool wear along with poor surface finish [ 1 , 2 , 3 ]. Nguyen, et al [ 4 ] showed that surface roughness decreases approximately 57.65% at lower feed rate per tooth (0.09 mm/z) in dry milling of 304 stainless steel.…”

Laser-Assisted High Speed Machining of 316 Stainless Steel: The Effect of Water-Soluble Sago Starch Based Cutting Fluid on Surface Roughness and Tool Wear

et al. 2021

View full text Add to dashboard Cite

Laser-assisted high speed milling is a subtractive machining method that employs a laser to thermally soften a difficult-to-cut material’s surface in order to enhance machinability at a high material removal rate with improved surface finish and tool life. However, this machining with high speed leads to high friction between workpiece and tool, and can result in high temperatures, impairing the surface quality. Use of conventional cutting fluid may not effectively control the heat generation. Besides, vegetable-based cutting fluids are invariably a major source of food insecurity of edible oils which is traditionally used as a staple food in many countries. Thus, the primary objective of this study is to experimentally investigate the effects of water-soluble sago starch-based cutting fluid on surface roughness and tool’s flank wear using response surface methodology (RSM) while machining of 316 stainless steel. In order to observe the comparison, the experiments with same machining parameters are conducted with conventional cutting fluid. The prepared water-soluble sago starch based cutting fluid showed excellent cooling and lubricating performance. Therefore, in comparison to the machining using conventional cutting fluid, a decrease of 48.23% in surface roughness and 38.41% in flank wear were noted using presented approach. Furthermore, using the extreme learning machine (ELM), the obtained data is modeled to predict surface roughness and flank wear and showed good agreement between observations and predictions.
