Improving the Efficiency of Cutting Tools through Application of Filtered Cathodic Vacuum Arc Deposition Coating Techniques: A Review

Abstract

The challenge of enhancing cutting tool life has been dealt with by many research studies. However, this challenge seems endless with growing technological advancement which brings about incremental improvement in tool life. The objective of this review paper is focused at assessing filtered cathodic vacuum arc deposition techniques applied on cutting tools and their effect on tool efficiency. The paper particularly picks filtered cathodic vacuum arc deposition (FCVAD) among other well-identified methods of coating like the Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD). Filtered Cathodic Vacuum Arc Deposition is the state of art in the coating technology finding wide application in the electronics industry and medical industry in addition to the machining industry, which is the concern of this review paper. This review is made in order to summarize and present the various techniques of FCVAD coatings and their applications, as investigated by various researches in the area.

Influence of Cr-Al-Si-N and DLC-Si Thin Coatings on Wear Resistance of Titanium Alloy Samples with Different Surface Conditions

“…The observed decrease in the R a roughness parameter (Table 4) allows us to assume some smoothing of the rough surface and conclude that less coating material is deposited on the surface protrusions than in the recesses. When the coatings are deposited on a surface after lapping with micro-grain abrasive, their morphological relief is represented mainly by a set of traditional structural features described in [81,82]: microdroplets (for the Cr-Al-Si-N sublayer) and isolated carbon particles having a spherical shape (for the DLC-Si outer layer). At the same time, the R a roughness parameter increases (Table 4).…”

DC vacuum arc deposition system with an anode generating magnetic field for preparation of TiN films

“…In modern industries, hard coatings for cutting tools are necessary for cost reduction or cutting accuracy. 1) Titanium nitride (TiN) coatings with a golden-yellow appearance are widely used for hard coating. They have properties such as a hard surface to reduce abrasive wear, a low coefficient of friction, excellent adhesion to substrates, high chemical inertness, and resistance to high temperatures.…”

“…7) The VAD method uses cathode or anode vapour plasma from a high current discharge in a vacuum environment to deposit coatings and thin films. 8,9) The plasma in the VAD method has preferred characteristics for hard coatings: (1) the emitted plasma vapor is highly ionized (30%-100%) 10) and (2) the emitted ions have a high kinetic energy (10-100 eV). 10) This plasma enhances the ability to independently control ion flux and ion energy at the substrate.…”
