Mar 31, 2021 · Analysis of ceramic carrier, stainless steel. The surface morphology of the ceramic carrier surface exposed to T. neapolitana is shown in Fig. 1a, b for method A and B respectively. Method A is a simple drying technique to show the biofilm and avoid its detachment during preparation. Analysis of oxide layer structure in nitrided grain Dec 07, 2019 · Abstract. The production of low-temperature reheated grain-oriented silicon steel is mainly based on the acquired inhibitor method. Due to the additional nitriding process, a high nitrogen content exists in the oxide layer, which changes the structure of the oxide layer. In this study, the structure of the surface oxide layer after nitriding was analyzed by scanning electron microscopy
- AbstractIntroductionMaterials and MethodsResults and DiscussionConclusionsConflict of InterestsAcknowledgmentA promising type of steel slag for applications is the ladle furnace (LF) slag, which is also known as the basic slag, the reducing slag, the white slag, and the secondary refining slag. The LF slag is a byproduct from further refining molten steel after coming out of a basic oxygen furnace (BOF) or an electric arc furnace (EAF). The use of the LF slag in further applications requires knowledge of its characteristics. The LF slag characterization in this paper has been performed using the following analytical methods:cUltrajet Mesodiagnostic Probabilistic Model for Surface  Moravíková J, Delgado Sobrino Daynier R, Koál P 2018 Analisis of the surface morphology of the S235JRG1 steel after an abrasive water jet cutting process (Trnava:Faculty of Materials Science and Technology.

Direct observation of pitting corrosion evolutions on May 22, 2018 · The surface height evolutions in DI water and in 100 mM NaCl solutions are distinct, as indicated in Fig. 1.In DI water, corrosion is associated primarily with the deepening of localized pits, as
Effects of molybdenum on the composition and nanoscale Surface analysis by time-of-flight secondary ion mass spectrometry, X-ray photoelectron spectroscopy and scanning tunnelling microscopy has been applied to provide new insight on Mo effects on the composition and nanostructure of the passive films grown in sulfuric acid on well-controlled Fe17Cr14.5Ni2.3Mo(100) austenitic stainless steel single crystal surfaces.
Apr 01, 2016 · For 4Cr13 stainless steel material, the temperature range of the temper brittleness is 550600 °C. In this study, the temperature of the tempering was lower than that of the temper brittleness. At the same time combination with the microstructure and morphology of the fracture surface, the temper brittleness mode did not occur. Surface morphology analysis of Duplex Stainless Steel (DSS The paper analyses the influence of clean manufacturing (green manufacturing) methods on the surface morphology of duplex stainless steel. The surface quality was compared using Power Spectral Density for dry and MQCL turning process. Analysis of signal power on the surface demonstrated that the wavelength is higher for dry turning than for machining using MQCL method. Using a DoE for a comprehensive analysis of the surface May 08, 2019 · The surface morphologies were observed via electron microscopy, and a lamella was prepared to facilitate the chemical composition analysis (EDX) with a transmission electron microscope (TEM). To study the subsurface layer and its defects, we produced metallographic specimens of all the samples; the items were observed by means of light and
The present paper discusses the impact of the speed of an abrasive water jet cutting process on some surface properties and morphology of the S235JRG1 steel. The values of the cutting speeds used for the analysis were of 100, 150 and 200 mm.min1 respectively.
