These kinetic mechanisms of eukaryote cells (type Dictyostelium discoideum) were tested in a two-plate cell detachment assay with the coated substrates as test plates and stainless steel discs as counter plates. The suspension of the cells in Sörensen buffer rested between the two plates, retained by the balance between gravity and capillary forces. All coatings influenced the cells leading to ...

The success of a functional coating is intrinsically linked to the improvement its surface properties, as it that will be in direct contact with environment and mechanical stresses when material used severe wear, fatigue, or corrosion applications. It has been shown, for example, by increasing factors such hardness increase durability coating/substrate system. Consequently, current research on ...

Electron beam (EB) physical vapour deposited (PVD) thermal barrier coatings (TBCs) have been used in gas turbine engines for a number of years. The primary mode of failure is attributed to oxidation of the bondcoat and growth of the thermally grown oxide (TGO), the alumina scale that forms on the bondcoat and to which the ceramic top coat adheres. Once the TGO reaches a critical thickness the T...

Titanium Nitride (TiN) coatings have led the way for providing increased wear resistance and extended life of cutting tools, whether carbide inserts or high-speed steel. Where the earliest applications were for high temperature substrate materials (carbides) and chemical vapor deposition (CVD) was the process of choice, later developments in the physical vapor deposition (PVD) technology, espec...

Different application methods for coatings have their individual advantages and disadvantages. Physical vapor deposition (PVD) titanium nitride are hard but cannot be produced economically in high coating thicknesses, example. Polymer derived ceramic (PDC) coatings, on the other hand, good oxidation protection properties can easily with worse mechanical properties. Therefore, a combination of d...

Chromium oxide coatings are chemically inert, have high mechanical strength, hardness and good optical characteristics; therefore, they have been widely used in many applications including corrosion protection, wear resistance, electronics, and optics. Cr2O3 is well suited for wear resistance applications, as it is one of the hardest oxides with 29.5 GPa hardness. Several deposition techniques ...

Solid Oxide Fuel Cells (SOFCs) are electrochemical conversion devices that produce electricity directly by oxidising a fuel. The interconnects between the individual cells need to be coated limit Cr(VI) evaporation from steel and preserve electrical conductivity. Physical Vapour Deposition (PVD)-coated samples with Ce/Co, Ce/Cu, Ce/MnCu, Thermal Spray (TS)-coated Mn/Co, Cu Mn/Cu AISI 441 were e...
