“…To obtain pure diamond membranes, the substrates need to be removed or separated by wet-chemical etching in boiled solutions (e.g., 30 wt% NaOH solution at 80 1C to remove the Si substrate) or precise laser cutting technique. 207 To generate diamond nanopores, different nanotechnologies can be employed such as top-down etching method and bottom-up overgrowth approach. 208 In the case of top-down etching methods, diamond films are etched by plasma (oxygen) or thermocatalytic (graphitization or burning) reaction through a porous mask, resulting in the generation of porous diamond films.…”

“…Diamond composites have been designed and synthesized through introducing other component(s) (e.g., other carbon materials, metals, carbides, oxidizes) into diamond films during/ after diamond CVD growth processes. 52 In this way, unique features of diamond electrodes are combined with those of added component(s). With diamond/β-SiC composites as the example, the gas precursors for the CVD growth of diamond and cubic SiC (β-SiC) were methane and tetramethylsilane, respectively.…”

Conspectus Diamond electrodes stepped onto the stage in the early 1990s for electroanalytical applications. They possess the features of long-term chemical inertness, wide potential windows, low and stable background currents, high microstructural stability at different potentials and in different media, varied activity toward different electroactive species, reliable electrochemical response of redox systems without conventional pretreatment, high resistance to surface fouling in most cases, and possibility of forming composites with different components such as other carbon materials, carbides, and oxidizes. Most diamond electrodes are prepared in microcrystalline or nanocrystalline form using chemical vapor deposition techniques. Starting from diamond films and diamond composites, numerous nanostructured diamond electrodes have also been produced. The features of diamond electrodes are therefore heavily dependent on the growth conditions and post-treatment procures that are applied on diamond electrodes such as introduced dopant(s), surface termination(s), surface functional group(s), added components, and final structure(s). Numerous applications of diamond electrodes have been explored in the fields of electrochemical sensing, electrosynthesis, electrocatalysis, electrochemical energy storage and conversion, devices, and environmental degradation. This Account summarizes our strategies to design different diamond electrodes, including diamond films, diamond composites, as well as their nanostructures. With respect to diamond films, the modulation of their dopant(s) and surface termination(s) as well as the attachment of functional modifier(s) onto their surface are discussed. Electrochemical hydrogenation and oxygenation of diamond electrodes are detailed at an atomic scale. As the examples of designing diamond electrodes at a molecular scale, photochemical and electrochemical attachment of modifier(s) onto diamond electrodes are shown. Moreover, electrochemical grafting of diazonium salts is proposed as a new technique to identify hydrogenated, hydroxylated, and oxygenated terminations of diamond electrodes. The introduction of additional component(s) into a diamond film to form diamond composites is then overviewed, where a hydrogen-induced selective growth model is proposed to elucidate the preparation of diamond/β-SiC composites. Subsequently, the production of various diamond nanostructures from diamond films and composites by means of top-down, bottom-up, and template-free approaches is shown. Electrochemical application examples of diamond electrodes are overviewed, covering direct electrochemistry of natural Cytochrome c on a hydroxylated diamond surface, sensitive electrochemical DNA biosensing on tip-functionalized diamond nanowires, and construction of high-performance supercapacitors using diamond electrodes and redox electrolytes. Our diamond supercapacitors, also named battery-like diamond supercapacitors or diamond supercabatteries, are highlighted since they combine the features of supercapac...

This study presents a revolutionary approach to surface enhancement through microwave-assisted cladding of a Ni and 15% BN particle mixture onto SS-304 substrates. Meticulous preparation steps were undertaken, including substrate cleaning and powder preheating, to ensure optimal adhesion and coating quality. Microwave hybrid heating using charcoal as a susceptor material facilitated rapid and uniform heating of the powder mixture, while a pure graphite sheet prevented contamination during the process. The experiment was conducted using a multimode microwave applicator at specific power and frequency settings, resulting in controlled heating for optimal coating formation. The precision of the microwave-assisted cladding process was illustrated through SEM images, revealing a uniform distribution of cladding particles across the substrate. Moreover, significant improvements in surface hardness and wear resistance were observed, with a 44.67% increase in surface hardness and a low wear rate of 0.0020 mm3/m. These findings highlight the effectiveness of the developed cladding technique in enhancing the mechanical properties and wear resistance of SS-304 substrates, paving the way for its potential application in various industries requiring reliable surface protection and durability under sliding contact conditions.
