Last 2 to 3 decades application of PVD (physical vapour deposition) hard coatings exponentially grows. However, the use of hard, thin films in the field of machine elements is the exception rather than the rule. The main problem lies in the relatively high contact pressure and the very complex loading of machine components, which demand a hard resistance surface and a tough core. In seminar it ...

Thin films of platinum deposited by physical vapor deposition (PVD) processes such as evaporation and sputtering are used in many academic industrial settings, for example to provide metallization when tolerance corrosive thermal cycling is desired, or electrocatalysis research. In this review, various practical considerations (Pt) on both Si SiO2 placed context with a comprehensive data review...

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 ...

This article summarizes the results of a project that integrates scientific and educational research in engineering field. It originated from technological appropriation process Physical Deposition Vapor Phase (PVD), which students Faculty Engineering have been involved to reach level entrepreneurship skills development. For this purpose, theoretical-methodological strategy based on integrative...

Physical vapor deposition (PVD) is one of the most important techniques for coating fabrication. With traditional trial-and-error approach, it labor-intensive and challenging to determine optimal process parameters PVD coatings with best properties. A combination three-dimensional (3-D) quantitative phase–field simulation a hierarchical multi-objective optimization strategy was, therefore, deve...

Machining can be outlined as the process of taking away material from a work piece in the grade of chips. During a machining process, isolated of the energy is turned into heat energy through the detritions yielded between the tool and the work piece and the plastic deformation of the work material in the machining zone. Turning is charmed by several constituents, for example, the cutting speed...

A commercial plasma enhanced chemical vapor deposition (PECVD) technique with planetary substrate rotation was used to apply a thin (200-400 nm thick) conformal diamond-like carbon (DLC) coating (known as a diamond-like nanocomposite (DLN)) on LIGA fabricated Ni-Mn alloy parts. The PECVD technique is known to overcome the drawbacks associated with the line-of-sight nature of physical vapor depo...

Interconnects, once the technological backwater of integrated circuit technology, now dominate integrated circuit cost and performance. As much as 90 percent of the signal delay time in future integrated circuit designs will be due to the interconnection of semiconductor devices while the remaining 10 percent is due to transistor-related delay. This shifts the thrust of critical research toward...
