Mechanisms for Orientation in Low Energy Ion Beam Assisted TiAlN Thin Film Growth
… and structure of off-normal sputter deposited TiAlN thin films has been investigated with the goal of better understanding the mechanistic pathways in ion beam assisted thin film growth for better control of film properties during deposition. The effects of incident angle for ion bombardment …

The impact of multilayer periodicity on texture, morphology, chemical stability and machining performance of titanium aluminum nitride/chromium nitride thin films
<p>Multilayer thin films of TiAlN/CrN were deposited at varying bilayer periods (lambda = 2, 4, 8 and 16 nm), along with a co-deposited (TiAlCr)N film and constituent TiAlN and CrN films, on both [111] silicon substrates and WC-4wt% Co inserts with an ISO SPGN 120308 geometry. The effects of …

Simultaneous machining of aerospace structural materials using poly-drills
… and four types of tool coatings (TiN-, TiCN-, TiAlN-, and TiSiN). Furthermore, analysis of variance was employed for estimating the relationships between the input parameters (spindle speed, feed, and tool coating) and the studied hole quality metrics. The focus was mainly on Al2024 alloys, …

Microstructure and properties of transition metal nitride and medium entropy alloy coatings
… mixed fcc TiN + fcc AlN phases into a single fcc TiAlN phase was observed with increasing substrate bias. Finally, a series of equiatomic medium entropy alloy CoCrNi coatings, including both monolayer coatings and a tri-layered CoCrNi/Ti coating, was deposited onto M2 substrates. It was found that …

Al 2 O 3 thin films: relation between structural evolution, mechanical properties and stability
… PECVD films further enables the oxidation of a TiAlN interlayer and the extrusion of TiO2 towards the film surface due to large volume expansion from TiO2, leading to a complete failure of the coating system. The relative stability of gamma-Al2O3 with respect to alpha-Al2O3 with 2.5 at% of Si, …

Raman microscopic studies of PVD deposited hard ceramic coatings.
… stresses within PVD coatings was evaluated. TiAlN/VN superlattice coatings with engineered stresses ranging -3 to -11.3 GPa were deposited onto SS and HSS substrates. Subsequent Raman measurements found a correlation coefficient of 0.996 between Raman band position and stress (determined via …

Deposition and characterisation of (Ti,Zr) based hard compound and multi-layer PVD films.
… line energy and shear modulus has given rise to TiAlN-ZrN films exhibiting Knoop micro-hardness in excess of 4000H[k]. Bulk and micro-analysis techniques have indicated a reproducible lamella coating structure can be formed, with accurate control of the layer period. Excellent levels of coating …
