Enhancement of pool boiling heat transfer can be attained with a number passive and active techniques. The paper experimentally analyses the impact laser treatment copper surfaces on distilled water ethyl alcohol. samples were modified beam to produce longitudinal grooves highly developed microstructures in textured area. Specimens different groove depths, widths micro-fin produced. results indicate significant influence processing flux dissipated from enhancement for all tested....
The main objective of the present work is to determine effects laser processing on properties WC-Co electro-spark deposited (ESD) coatings steel substrates. Tungsten carbide have been applied substrates using a manual electrode feeder, model EIL-8A. beam (LBP) was performed an Nd:YAG fiber laser. microstructure and treated/melted were evaluated by means scanning electron microscopy (SEM), X-ray diffraction (XRD), surface geometric structure (SGS) roughness measurements adhesion,...
The paper explores the possibilities of using carbonyl iron in form a powder for manufacture radar-absorbing paints – reducing radar signature objects that they cover. attenuation values range 4–18 GHz various coating thicknesses, ranging from 0.5 to 2.00 mm with increment, and different absorber content −75% 80%, as well use two binders epoxy resins hardeners, were investigated. For frequency 18 1.5 thick 75% content, Epidian 112 resin Saduramid 10/50 hardener used binder, maximum level...
Abstract A number of modern surface processing methods use an energy flux. The examples include electro-spark deposition (ESD) and laser beam (LBP). work concerns the study Cu-Mo coatings deposited on C45 carbon steel, which were then eroded with a beam. analysis included microstructure, measurements macrogeometry microhardness, corrosion resistance tests selected areas after treatment. applied ELFA-541 subjected to Nd:YAG treatment variable parameters. problem presented in can be used...
The paper presents an analysis of the functional operational properties multilayer coatings for use in military technology field masking. developed coating systems are characterized by innovation due to their small thickness when compared those currently used global defence contractors while maintaining re-emission coefficient required camouflage be effective optical range. Their service life and durability were assessed terms based on measurements attenuation coefficients, surface geometric...
The laser treatment of surfaces enables the alteration their morphology and makes them suitable for various applications. This paper discusses use a beam to develop surface features that enhance pool boiling heat transfer. Two types structures (in 'macro' 'micro' scale) were created on samples: microfins (grooves) roughness. impact pulse duration scanning velocity height roughness at bottom grooves was analyzed with high precision optical profilometer microscope. results indicated highest...
The use of solar panels in low-power applications is an increasingly developing topic. Various methods are currently used to obtain the highest possible panel power generation efficiency. determining maximum point (MPP) and its tracking under constant development, resulting creation new algorithms accelerate operational efficiency while maintaining good parameters. Typically, these only high-power photovoltaic installations. Due problems from adjustment MPP working conditions for charge a...
Diamond-like carbon (DLC) coatings are currently used in many areas of the economy.Due to their unique properties, such as high hardness, low friction, and wear resistance, also industry, especially on machine parts exposed increased wear.The paper presents results operational tests diamondlike deposited physical vapor deposition (PVD) process samples made 4H13 stainless steel.The properties DLC were assessed based microstructure analysis, nanohardness roughness measurements, tribological...
