Surface texture, defined as “the local deviation of a surface from a perfectly flat plane “[1], is a crucial determinant of the functionalities of various materials, be they natural or man-made. In nature, surface texture has evolved to meet the diverse survival needs of living organisms. For instance, Darkling beetles Figure 1(a) and some types of cacti Figure 1(b) that inhabit desert environments possess specialised bumps, grooves, or 3D hierarchical structures on their body surfaces, which condense water from the air [2,3]. The surface texture of the lotus leaf Figure 1(c) is the most cited example of hydrophobic surfaces, bordering on being a cliché. Manmade surface textures can be perceived as nominal or actual. The nominal surface refers to the intended contour of the surface, while the actual surface is determined by the manufacturing processes used to create it [5]. Surface texture is typically categorised into roughness, waviness, lay, and flaws Figure 2. Roughness is determined by the characteristics of the materials and processes used to form the surface and manifests as small, finely-spaced deviations from the nominal surface. Waviness, on the other hand, consists of much larger deviations caused by factors such as work deflexion, vibration, and heat treatment. Roughness is typically superimposed on waviness. The lay of the surface texture refers to the predominant direction or pattern of the surface, while flaws are irregularities that occur occasionally on the surface, such as cracks, scratches, and inclusions. Although flaws are related to surface texture, they also affect surface integrity. The texture of a surface can contribute to aesthetics, safety, assembly, and functionality. For example, the shininess or dullness of a surface can impact its perceived aesthetic value, while the surface’s mechanical properties, absorption, friction and wear, corrosion and wear behaviour, adhesion, and electrical and thermal conductivity, can affect its overall functionality. Smooth surfaces are better suited for electrical contacts, while rough surfaces are better suited for water repellency and friction like in brakes. The texture is the single driving cause for the presence or absence of friction between mating surfaces. As early as the 18th century, Bernard Forest de Bélidor recognised that friction arises from the numerous hemispherical peaks and valleys on the mating surfaces, a concept furthered by Coulomb in his exposition of lubrication [8]. There are various categories of texturing methods, including addition, removal, displacement of material, and self-forming methods [9]. The most common industrial texturing processes such as shot blasting, milling, grinding, etching, lithography, laser methods, and manual polishing fall under the removal category. Replica methods such as master printing and microcontact printing, and 3","PeriodicalId":21995,"journal":{"name":"Surface Engineering","volume":"39 1","pages":"239 - 244"},"PeriodicalIF":2.8,"publicationDate":"2023-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48271406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sudarshan","doi":"10.1080/02670844.2023.2195774","DOIUrl":"https://doi.org/10.1080/02670844.2023.2195774","url":null,"abstract":"The above excerpt from an English Translation of Pliny the Elder’s Latin book on Natural History dated 77 CE may perhaps be the earliest written record of the use of a sol-gel type anticorrosion coating on metals. The war of man against corrosion has been relentless. We have devised various ways to protect various metals from corrosion – through judicious materials selection, application of various kinds of inorganic and organic coatings, using corrosion inhibitors, cathodic protection, and design elements that prevent corrosion. However, nature likes to revert back to its lowest thermodynamic form as an oxide from which we extract almost all materials for industrial use. Although modern scientific literature on corrosion protection coatings can be traced back to the era of pack cementation and electrodeposition in general, followed by aluminizing of iron in the twentieth century, the systematic study of sol-gel type coatings mitigating corrosion is relatively recent. Sol-gel is a surprisingly simple process that involves dipping the substrate with a sol to form a tacky, adherent gel film on curing, which then may or may not be subsequently calcined to get a microporous and mesoporous protective organic, inorganic or hybrid corrosion protective coatings. The advantages of sol-gel coatings, vis., benign conditions of deposition (e.g. relatively low temperatures) and the ability to produce coatings on complex shapes without the need for machining or melting (hence no expensive equipment) has led to a significant amount of work on sol-gel based protective coatings primarily for metals. The ease of application led to a burst of research since the turn of the century (Figure 1) has also been driven by the need for creating environmentally friendly materials and processes to replace the traditional chromium-based and/or solvent-based anti-corrosion coatings. Sol-gel-based coatings can be brought about through an inorganic or organic route. The former, which was probably the technique described by Pliny the Elder at the start of the Common Era, involves the gelation colloidal suspension of nanometric particles of inorganic materials (e.g. lead oxide, lead carbonate, and calcium sulphate in Pliny’s antipathia) to form a network in a continuous liquid phase. This is however rarer than the organic route in which a prepolymer is polymerized into a gel to form a protective network. The alkoxide-based process – the formation of an oxide (usually silicon oxide) network by progressive condensation of a metalloid alkoxide in a liquid medium is a classic example (Figure 2). In this alkoxide route, subsequent sintering the gel-coated substrate to high temperatures (440–1200°C) for short heating times, about 15 minutes, leads to the hardening of the coating to various degrees due to the formation of the oxides. Alkoxide-based sol-gel corrosion coatings have many benefits such as ease and flexibility of the fabrication process, the abundance of commercially availabl","PeriodicalId":21995,"journal":{"name":"Surface Engineering","volume":"39 1","pages":"135 - 138"},"PeriodicalIF":2.8,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41345745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two approaches have been proposed for determining the adhesion strength of the cold spray-coated substrate. The interfacial shear strength approach combines the fragmentation test with a modified Weibull model. Fragmentation testing can examine materials with geometrical (roughness) and property (strength) variations for cold spray-coated specimens. The results give an insight into local strength and the coating strength distribution. The fracture toughness approach uses an electrical four-point probe to identify crack initiation and calculate the energy release rate of the coating. Sn coatings between 74 and 120 μm show an interfacial shear strength between 25 and 53 MPa and an energy release rate between 15 and 32 J m–2. The measured interfacial shear strength was independent of the coating thickness, while the energy release rate depends on the coating thickness.","PeriodicalId":21995,"journal":{"name":"Surface Engineering","volume":"39 1","pages":"161 - 173"},"PeriodicalIF":2.8,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43802632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that Na2SiO3, in the form of a silicon-oxygen bond (Si-O), could effectively bond with the coating surface inside the pore defects. In addition, the optimal concentration was proved to be 1 mol/L, and the corresponding passivation current density could be reduced to (2.38 ± 0.33) × 10−6 A/cm2, which was an order of magnitude lower than that of as-sprayed coating.
