Abstract:

It is shown that the common practice of imaging the plasma directly onto the spectrometer entrance slit in analytical glow discharge optical emission spectrometry (GDOES) may induce analytical error when used with samples which are chemically heterogeneous. An alternative method for transferring the source emission to the entrance slit is demonstrated to eliminate the potential error, suggesting its routine use in analytical GDOES.

Abstract:

The glow discharge optical emission spectroscopy (GDOES) depth profiles of zinc-coated copper substrates polished by different mesh size sandpapers are well fitted with the mixing-roughness-information (MRI) model. Based on the MRI fits, the copper substrate roughness parameters and the coating layer thickness values are extracted. Using the so-called 84% to 16% method, the depth resolution values of the measured GDOES depth profiles are obtained, thereby the respective roughness parameters are determined. The obtained zinc-coated copper substrate roughness values are correlated with the exper

Abstract:

The integrity and quality of the passive layer is key to the overall performance for corrosion resistance of a coated surface. The evaluation of a Cr-based chemical conversion coating applied on an aluminium alloy has been conducted deploying an electrochemical method (EIS - Electrochemical Impedance Spectroscopy) and a spectroscopical method (GDOES - Glow Discharge Optical Emission Specstropscopy) for the depth profile and distribution of elements on the surface. The complementarity of the two techniques confirm and justify the obtained performance.

The effect of copper on oxidation behavior of a C-Si-Mn steel was investigated. The samples were heated to 820°C and held for 75s under four different dew points with 5vol% hydrogen. The results of glow discharge optical emission spectrometry (GDOES), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) analysis techniques revealed the differences in oxidation. It is proposed that the steel containing 0.3 wt.% copper has less external oxidation of silicon and manganese compared to the steel containing no copper for all different dew points.

Wear-resistant coatings development is progressively increasing steeply due to their advantages when applied to mechanical components subjected to abrasive and destructive environments. Titanium nitride (TiN) coating is typically used to enlarge tools and components’ service life and improve their surface quality. On the other hand, AlTiSiN coating intends to be applied to more aggressive environments such as spatial satellites components exposed to solar radiation, extremely high temperatures, and random particles impact.

Abstract:

Surface mechanical attrition treatment (SMAT) is a mechanical peening process used to generate ultrafine grain surfaces on a metal. SMAT was carried out on pure magnesium using different attrition media (zirconia [ZiO2], alumina [Al2O3], and steel balls) to observe the effect on microstructure, surface residual stress, surface composition, and corrosion. Surface contamination from SMAT was characterized using glow discharge optical emission spectroscopy (GDOES). The SMAT process produced a refined grain structure on the surface of Mg but resulted in a region of elemental contamination extendin

Abstract:

Abstract Hot pressing of titanium and carbon steel leads to the formation of a diffusion layer at the interface. Depending on the carbon content of the steel used, it either exclusively contains TiC or additional other phases. In the case of steel with a medium carbon concentration (0.67 wt.% C), a pure TiC layer forms. A preparation methodology was developed to make statements about functional and microstructural properties of the respective layers such as layer thickness, porosity, or grain size. However, apart from the diffusion layer’s microstructure, it also reveals the microstructure of

Abstract:

The hot stamping process consists to heat the steel blank, at total austenitization temperatures and to transfer it into the press tooling for forming and fast cooling to fully martensitic transformation. This transference from furnace to press stage promotes some steel oxidation. The application of metallic coatings avoids this phenomenon. The Al-Si coating, a patented process, has been the most applied on steel. Hence, alternative coatings like Zn-Ni are under development. It is known that this furnace heating causes chemical elements diffusion that results in intermetallics formation. This
