“…As a result, the adhesion strength of composite coating increased to 30 ± 2 MPa. In previous study, the influence of size of grit particles (50 µm and 250–320 µm) used in sand blasting on various surface properties was investigated [ 163 ]. The pretreatment caused surface morphological changes, pits formation, and caused it to become rougher as the grit size increased.…”

“…There are several factors influencing the blasting process, such as the physical properties of grain particles, operation time, working distance between the targeted surface and abrasive materials, and others. A study by Grubova’s research group used a sand blasting pretreatment method on a titanium surface before the coating process [ 163 ]. The purpose of this treatment was to roughen the surface of the titanium in order to enhance surface properties such as hardness and strength of coating adhesion.…”

The astonishing outbreak of SARS-CoV-2 coronavirus, known as COVID-19, has attracted numerous research interests, particularly regarding fabricating antimicrobial surface coatings. This initiative is aimed at overcoming and minimizing viral and bacterial transmission to the human. When contaminated droplets from an infected individual land onto common surfaces, SARS-CoV-2 coronavirus is able to survive on various surfaces for up to 9 days. Thus, the possibility of virus transmission increases after touching or being in contact with contaminated surfaces. Herein, we aim to provide overviews of various types of antiviral and antimicrobial coating agents, such as antimicrobial polymer-based coating, metal-based coating, functional nanomaterial, and nanocomposite-based coating. The action mode for each type of antimicrobial agent against pathogens is elaborated. In addition, surface properties of the designed antiviral and antimicrobial polymer coating with their influencing factors are discussed in this review. This paper also exhibits several techniques on surface modification to improve surface properties. Various developed research on the development of antiviral/antimicrobial polymer coating to curb the COVID-19 pandemic are also presented in this review.

“…Therefore, the contact stiffness between the coating and the substrate increases, which further enhances coating adhesion to the substrate. An 800 nm hydroxyapatite coating was deposited on sandblasted titanium implant by RF magnetron sputtering [26], and morphology analysis of the sandblasted Ti substrate revealed that the homogeneously deformed texture induced by sandblasting pretreatment was beneficial for achieving the desired coating adhesion to the substrate. Sandblasting and acid etching pretreatments of WC-Co substrate surface have been adopted [21] to improve the adhesion of diamond coating to the substrate by creating adequate mechanical interlocking between the diamond film and the roughened WC-Co substrate surface and by sufficiently increasing nucleation density of the diamond film.…”

Effect of Surface Pre-Treatment on the Adhesion between HiPIMS Thick Cu:CuCNx Coating and WC-Co Shim

High-power impulse magnetron-sputtering thick metal/carbon–nitride-doped metal-matrix multilayer nano-composite coating can be applied to cutting-tool holder components to improve cutting insert’s life. One of the challenges of such an add-on solution is the poor adhesion between the thick coating and the hard alloy substrate, such as WC-Co shim. This work presents a study on WC-Co substrate surface preparation methods for HiPIMS coating and its adhesion improvement. Three mechanical surface pretreatment methods were investigated: machining (grinding), diamond polishing, and grit blasting. White-light interferometry was used for substrate surface texture measurement before and after pretreatment. It was demonstrated that, compared to machining and diamond polishing, grit blasting can significantly improve the interface adhesion between the ~200 µm-thick Cu:CuCNx coating and WC-Co shim. Grit blasting was also found to be beneficial for improving the cutting insert’s life in the external turning process. In turning tests, the coating lifetime for grit-blasted shim was more than 90 minutes, whereas the coating lifetimes for machined shim (conventional shim) and diamond-polished shim were ~85 minutes and ~70 minutes, respectively. Further, by comparing the HiPIMS gradient chromium pre-layer between the coating and substrate for the different shims, the study also explained that the quasi-isotropic surface texture of grit-blasted shim is more advantageous for coating–substrate interface adhesion.

“…The cleaned contaminants reported to incur cost as much as 0.25% of gross domestic product (GDP) and 2.5% additional release of CO 2 . 2 Shot blasting process generates a mixture of used blasting media and waste from the cleaned surface which needs to be suitably disposed. 3 Waste from the blasting media contains valuable metals such as iron, and its disposal without recovery brings adverse economic and environmental impact.…”

Acid leaching is extensively employed for extractive metallurgy, but its use on reclamation of shot blasting media has not been extensively studied. The parameters of acid leaching process such as rate of stirring, the leached material grain size, the solid (material) to liquid (acid) ratio, type of acid, concentration of acid, leaching temperature, and leaching duration govern the effectiveness of this process. The goal of this article is to investigate the effectiveness of acid leaching to recover the iron from used shot blasting media. Influence of varying leaching durations on the recovery percentage of iron from the used shot blasting media is investigated, and it is found that acid leaching can remove impurities from used shot blasting media and it can successfully recover 73.6% of iron on the particle surface level and 44.3% of iron overall. Hence, it is a feasible process for recovery of iron from used shot blasting media.
