Abstract:

Titanium diboride (TiB2) has been investigated as a potential candidate for several industrial applications, such as: cutting tools, electric devices, wear parts and many more fields of application. The main drawback of TiB2 is its brittle nature, which has limited its range of applications. Diamond-like Carbon (DLC) has been used in industrial applications, mainly for wear resistant parts. However, the application of DLC films has been limited by the level of internal stress accumulated during deposition. This thesis investigates the deposition of TiB2/DLC multilayer wear resistant coatings t

Abstract:

Niobium is well known for its excellent corrosion resistance based on the formation of a stable passive oxide layer, which protects the metal against corrosion in most aqueous media and makes it an interesting candidate for corrosion resistant coating applications. However, deposition of Nb films is restricted to few technologies and difficulties arise from the toxic nature of the electrolytes employed in electrodeposition of Nb, the high reactivity of the metal with residual gases in vacuum plasma spraying and its high melting point (Tm = 2500 0C) in PVD deposition.

Abstract:

Thermal barrier coatings (TBCs) are advanced material systems used in the hot sections of gas turbines. The TBCs are designed to provide insulation against hot gases by a ceramic top coat and to provide oxidation and corrosion resistance by a metallic bond coat. As the operating environment is harsh and complex, the TBC often requires stricter material properties. Failure of TBCs can limit the longevity of the turbine severely. In this study, failure caused by erosion has been the main focus. The erosion behaviour of TBCs processed by atmospheric plasma spay (APS), electron beam physical vapou

A study and comparison of two commercially available and competitive physical vapour deposition techniques has been made.

The coatings have subsequently been analysed by a variety of methods and the results reported here.

PVD hard ceramic coatings grown via the combined cathodic arc/unbalance magnetron deposition process were studied using Raman microscopy. Characteristic spectra from binary, multicomponent, multilayered and superlattice coatings were acquired to gain knowledge of the solid-state physics associated with Raman scattering from polycrystalline PVD coatings and to compile a comprehensive spectral database. Defect-induced first order scattering mechanisms were observed which gave rise to two pronounced groups of bands related to the acoustical (150-300cm[-1]) and optical (400-750cm[-1]) parts of the

This diploma thesis deals with the durability of PVD coating in front groove milling. In the theoretical part there is the analysis of high-speed steels, a survey of milling and an overview of coating methods. The experimental part is focused on the power ratios during milling with a router cutter and its wear. From the experiment it is possible to conclude that nanocomposite coatings reduce cutting forces, but do not produce the most durable tool under the cutting conditions.

Both coatings were deposited by planar magnetron DC sputtering, as separate steps in a single PVD-process.

Abstract:

The work covers studying of influence of indexes of an ion-plasma vacuum-arc deposition method to the structure, composition and properties of Ti-Al-N/Zr-Nb-N/Cr-N multilayer nanostructured coatings (MNC). The average crystallites size within the layers is about 5-10 nm. Received coatings are featured by absence of any change in the composition and properties after heating up to 1000 ºС, the coatings hardness is up to 36,6GPa, Young's modulus of elasticity is up to 580 GPa, plastic work of deformation is up to 64 %, adhesive strength is about 100 N and coefficient of friction is 0,45.

Abstract:

Hard nanostructured TiAlN coatings have gained high importance in the field of protective tribological coatings. Nevertheless, their use regarding high temperature (>800°C) applications such as dry high speed machining still remains a challenge. Addition of elements such as Ta or Y has shown a beneficial impact on these properties. But for a better performance of these coatings, an in-depth understanding of their oxidation and wear mechanisms over a wider range of temperatures is needed which is currently unavailable in the literature. This work investigated the wear and oxidation properties o

Abstract:

Mechanical properties such as fracture strength and fracture toughness of thin films obtained from Physical Vapour Deposition are difficult to evaluate since the relative small dimension of such coatings. Furthermore, the fracture modes are not well understood yet. In this thesis novel techniques have been used in order to fill the lack of information about mechanical properties of hard thin coatings. In-situ bending tests were carried out in order to study the fracture strength. The evaluation of such property and the modes of fracture were studied via direct observation inside the Scanning E

<p>This Thesis presents two different deposition techniques for the synthesis of Ti<sub>2</sub>AlC coatings. First, I have fabricated Ti<sub>2</sub>AlC coatings by high velocity oxy-fuel (HVOF) spraying. Analysis with scanning electron microscopy (SEM) show dense coatings with thicknesses of ~150 µm when spraying with a MAXTHAL 211<sup>TM </sup>Ti<sub>2</sub>AlC powder of size ~38 µm in an H<sub>2</sub>/O<sub>2</sub> gas flow. The films showed good adhesion to stainless steel substrates as determined by bending tests and the hardness was 3-5 GPa. X-ray diffraction (XRD) detected minority phase

Abstract:

Le procédé de dépôt physique en phase vapeur assisté par plasma thermique (PS-PVD) consiste à évaporer le matériau sous forme de poudre à l’aide d’un jet de plasma d’arc soufflé pour produire des dépôts de structures variées obtenus par condensation de la vapeur et/ou dépôt des nano-agrégats. Dans le procédé de PS-PVD classique, l’intégralité du traitement du matériau est réalisée dans une enceinte sous faible pression, ce qui limite les phénomènes d’évaporation ou nécessite d’utiliser des torches de puissance importante. Dans ce travail, une extension du procédé de PS-PVD conventionnel à un p
