The preparation of surfaces for coating processes is indispensable maximal adhesion and good results. These technical can be treated by chemical, mechanical, or physical procedures. In thermal spray coating, grit blasting a standard process surface preparation. This mechanical roughening activation the fast easy to handle. On negative side, gets wasted generated pattern inflexible. Therefore, attempts substitute with laser application discussed in this article. Herein, theoretical evaluation...
In this study, we investigated the effect of spray angle on microstructure, bonding quality, and scratch resistance cold-sprayed SS316L coatings SS304 substrates. The were deposited at angles 45°, 60°, 75°, 90° using a high-pressure cold system. A comprehensive analysis relationship between coating properties was conducted, with particular focus fracture toughness porosity. Scratch testing, combined real-time acoustic emission monitoring, enabled precise identification failure mechanisms...
This study is focused on the high-temperature corrosion evaluation of selected thermally sprayed coatings. NiCoCrAlYHfSi, NiCoCrAlY, NiCoCrAlTaReY, and CoCrAlYTaCSi coatings were base material 1.4923. used as a cost-efficient construction for components power equipment. All evaluated using HP/HVOF (High-Pressure/High-Velocity Oxygen Fuel) technology. High-temperature testing was performed in molten salt environment typical coal-fired boilers. exposed to 75% Na2SO4 25% NaCl at temperature 800...
In order to extend the life of boilers by applying an anti-corrosion coating without need dismantle them, it is advisable find coatings that can be applied using cheaper and portable techniques, such as Twin Wire Arc Spray technology (TWAS). this study, we compare selected NiCr-based two uncoated steel substrates (steel 1.7715 1.4903). Two coatings, Cr3C2 - 25% NiCr Hastelloy C-276 are deposited High velocity oxygen-fuel (HVOF) three NiCrTi, NiCrMo, Inconel 625, TWAS. addition corrosion...
This review provides a comprehensive discussion on surface engineering of medical devices, with central focus the relatively new and innovative technology, known as cold spray. The introduction sets stage for in-depth antimicrobial biomedical surfaces, which highlights importance design modification device surfaces. Moreover, current advancements in coatings emerging trends are briefed that shaping future landscape industry. is contemporary technologies, notable emphasis application also...
In laser cladding, the final structure of coatings and thus their functional properties are dependent on process parameters used initial powder composition. This study focuses cladding WC-NiCrBSi coatings. As is a blend 60% tungsten carbide spherical particles 40% NiCrBSi matrix, carbides' morphology distribution in coating would be parameters. Coatings were cladded using solid state by varying key parameters: speed, feed rate power. Cladded evaluated terms microstructure, hardness abrasive...
Laser marking is an advanced technique used for modification of surface optical properties. This paper presents research on the influence laser corrosion properties stainless steel. Processes during beam–surface interaction cause structure and color changes can also be responsible reduction resistance surface. Corrosion tests, roughness, microscopic, energy dispersive x-ray, grazing incidence x-ray diffraction, ferrite content analyses were carried out. It was found that increasing heat...
