Comparison of the Cathodic Protection of Epoxy Resin Coating/Zinc-Rich Coatings on Defective Areas under Atmospheric and Immersion Conditions: The Secondary Activation of Zinc Particles Coatings (IF 3.4) Pub Date : 2024-03-12 Wei Zhang, Wenting Xia, Zhiwei Chen, Guoqing Zhang, Sicheng Qian, Zhifeng Lin
The cathodic protection provided by epoxy coating/epoxy zinc-rich coatings on defective areas under atmospheric and immersion conditions was studied via a Q235 wire beam electrode (WBE), scanning electron microscopy, X-ray diffraction, and surface morphology analysis. The results showed that the cathodic protection processes under the two test conditions displayed significant differences. The effective

Preservative Effects of Flaxseed Gum-Sodium Alginate Active Coatings Containing Carvacrol on Quality of Turbot (Scophthalmus maximus) during Cold Storage Coatings (IF 3.4) Pub Date : 2024-03-12 Xinrui Yang, Shiyuan Fang, Yao Xie, Jun Mei, Jing Xie
In this article, the effect of active coatings of flaxseed gum (FG) and sodium alginate (SA) containing carvacrol (CA) on the quality of turbot (Scophthalmus maximus) after storage at 4 °C for 18 days was evaluated. The experimental results showed that FG/SA-CA could effectively inhibit the growth of microorganisms. At the same time, FG/SA-CA reduced the value of odorous-related compounds including

Temperature Analysis in Cubic Boron Nitrate Cutting Tool during Minimum Quantity Lubrication Turning with a Coconut-Oil-Based Nano-Cutting Fluid Using Computational Fluid Dynamics Coatings (IF 3.4) Pub Date : 2024-03-13 Subhash Khetre, Arunkumar Bongale, Satish Kumar, B. T. Ramesh
The minimum quantity lubrication (MQL) approach is used for improving tool life at a low cost, and it is environmentally friendly. When compared to traditional flood cooling technology, the flow rate in MQL is thought to be 10,000 times lower. The workpiece’s surface smoothness is enhanced by continuous chip formation during turning, but because the tool is always in touch with the chip, a crater wear

Enhanced Wear and Corrosion Resistance of AZ91 Magnesium Alloy via Adherent Si-DLC Coating with Si-Interlayer: Impact of Biasing Voltage Coatings (IF 3.4) Pub Date : 2024-03-13 Changqing Cui, Chunyan Yang
Magnesium alloys are the lowest-density structural metals with a wide range of applications, such as aircraft skins, engine casings and automobile hubs. However, its low surface hardness and non-corrosion resistance in natural environments limit its wide range of applications. In this work, Si-DLC coatings (Si: 15 at.%) are fabricated on AZ91 alloy using a hollow cathode discharge combined with a DC

Properties of Diamond-like Tungsten-Doped Carbon Coatings Lubricated with Cutting Fluid Coatings (IF 3.4) Pub Date : 2024-03-13 Krystyna Radoń-Kobus, Monika Madej, Joanna Kowalczyk, Katarzyna Piotrowska
In this paper, the authors investigated the impact of DLC coatings doped with tungsten (a-C:H:W) coatings obtained using plasma-assisted physical vapor deposition (PVD) on the properties of the 100Cr6 steel. The results of the 100Cr6 steel specimens with and without the coating were compared. Scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) analysis were used to observe the morphology

Mechanical Characterization of Resistance-Welded and Seamless API 5L X52 Pipes: A Comparative Study Coatings (IF 3.4) Pub Date : 2024-03-13 Gerardo Terán Méndez, Selene Irais Capula-Colindres, Julio César Velázquez, Daniel Angeles-Herrera, Noé Eliseo González-Arévalo, Esther Torres-Santillan, Arturo Cervantes-Tobón
It is well known that the mechanical properties of a steel plate depend on the anisotropy of the material and the rolling directions. This paper presents the results of the Charpy V-Notch (CVN) impact test for the ST, TL, TS, LS, LT, 45°, and SL directions in API 5L X52 pipelines with electric-resistance-welded (ERW) and seamless (SMLS) pipes. Charpy specimens were manufactured and tested according
