Distribution Of Elements

The X-ray and mass spectroscopy of secondary ions, the phase composition, the distribution of elements in the depth of coating on the basis Ti-Al-N treated by the (Cr+B) ion beam was studied. It was established that the ion implantation of B and Cr in TiAlN coating leads to changes in the chemical composition of the surface layer and the redistribution of the elements in the surface layer. This fact leads to change of tribological properties and microhardness.

Protective coatings provide protection of structures against corrosion, but they also aim to meet marketing requirements – decorative qualities. One of the representatives of protective coatings are fire coatings based on Al and Al-Si, which have been used, among others, in the automotive industry. The production of Al-Si coatings using the fire method (known as: immersion) consists in immersing a previously degreased detail in a bath of molten coating metal. Al-Si coatings are applied permanently, and the connection between the coating and the substrate is ensured by the mutual diffusion of aluminum and iron, which leads to the formation of intermetallic phases. The study examines Al-Si coatings used in the automotive industry. The research included assessment of coatings in terms of structure, hardness distribution of elements, and surface condition (roughness). The chemical composition of the coatings was determined using EDX microanalysis and phase composition by diffractometric analysis. The final assessment focused on the impact of bending on the quality of the connection between the substrate and the coating.

Galvanomagnetic Effects

The article shows the ability to control magnetic properties due to modulation of phases in the film with varying temperature of growth. So, at low growth temperatures, a film is formed with an axis of easy magnetization in plane. An increase in temperature leads to a change in the phase composition of the film. It is shown that the presence of even a small component of the magnetization vector in the perpendicular direction leads to the appearance of a thermomagnetic effect of a large magnitude with respect to thermal noise

Present Distribution

The recently developed parallel electron energy loss spectrometers (PEELS) have led to a significant reduction in spectrum acquisition time making EELS more useful in many applications in material science. Dwell times as short as 50 msec per spectrum with a PEELS coupled to a scanning transmission electron microscope (STEM), can make quantitative EEL images accessible. These images would present distribution of elements with the high spatial resolution inherent to EELS. The aim of this paper is to briefly investigate the effect of acquisition time per pixel on the signal to noise ratio (SNR), the effect of thickness variation and crystallography and finally the energy stability of spectra when acquired in the scanning mode during long periods of time.The configuration of the imaging system is the following: a Gatan PEELS is coupled to a CM30 (TEM/STEM) electron microscope, the control of the spectrometer and microscope is performed through a LINK AN10-85S MCA which is interfaced to a IBM RT 125 (running under AIX) via a DR11W line.

A knowledge of the distribution of chemical elements in a specimen is often highly useful. In materials science specimens features such as grain boundaries and precipitates generally force a certain order on mental distribution, so that a single profile away from the boundary or precipitate gives a full description of all relevant data. No such simplicity can be assumed in life science specimens, where elements can occur various combinations and in different concentrations in tissue. In the latter case a two-dimensional elemental-distribution image is required to describe the material adequately. X-ray mapping provides such of the distribution of elements.The big disadvantage of x-ray mapping hitherto has been one requirement: the transmission electron microscope must have the scanning function. In cases where the STEM functionality – to record scanning images using a variety of STEM detectors – is not used, but only x-ray mapping is intended, a significant investment must still be made in the scanning system: electronics that drive the beam, detectors for generating the scanning images, and monitors for displaying and recording the images.
