“…A nanoindentation workstation (Ultra-Micro Indentation System 2000, CSIRO, Sydney, Australia) equipped with a Berkovich indenter [25,26] was used to determine the mechanical properties of the films. To ensure that only the film properties were measured, nanoindentation was conducted under load control with a maximum load of 0.5 mN, under which the maximum penetration depth was found to be ~0.1 m (see Results and discussion section), well below 10% of the total film thickness of ~2 m.…”

A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT2 Abstract Sol-gel dip-coated optical coatings, copper-cobalt oxides on aluminium substrates, were thermally treated at different annealing temperatures in the range 500 -650 °C. The resulting films were characterized using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), UV-Vis-NIR spectrophotometry and nanoindentation techniques. The crystallinity of CoCu 2 O 3 enhanced significantly, with increasing annealing temperature from 500 to 650 °C, while the electronic structure and bonding states of the copper-cobalt oxides matrix remained unchanged. UV-Vis-NIR analysis showed that the solar absorptance (α) of the coatings changed with increasing of annealing temperature and an optimum α (84.4%) was achieved at 550 °C, which also coincides to the maximum tensile residual stress of the coating.Nanoindentation tests exhibited an increasing trend in both the hardness (H) and elastic modulus (E) of the coatings with increase in annealing temperature, although a slight decrease in the H/E ratio was also observed. The experimental studies were complemented by Finite Element Modelling (FEM). The results showed that, under mechanical loading, the stress and plastic deformation were concentrated within the coating layers. As such, the likelihood of delamination of the coating layer upon unloading would be reduced.

“…The residual stresses which commonly exist in thin lms arise, in part, as a result of constraints imposed by their substrates. 29,30 In this case, the origin of residual stresses is mainly attributed to the large thermal expansion anisotropy of Ti 5 Si 3 and thermal expansion mismatch that exists between the lm and substrate. Similar to other non-cubic silicides with a chain-like structure, polycrystalline Ti 5 Si 3 exhibits a strong coefficient of thermal expansion (CTE) anisotropy between the c-and a-directions, which introduces thermal residual microstresses in the grains during cooling following the deposition process.…”

A novel TiC-Ti 5 Si 3 nanocomposite film was successfully engineered onto a Ti-6Al-4V substrate using a double glow discharge plasma technique. This type of film exhibits a self-toughened, hierarchical structure, consisting of cauliflower-like Ti 5 Si 3 grains together with TiC nanoparticles distributed at the boundaries. The electrochemical behavior and electronic properties of the passive layers formed on the TiC-Ti 5 Si 3 nanocomposite film were compared to a monolithic Ti 5 Si 3 film and uncoated Ti-6Al-4V in a 3.5 wt% NaCl solution by various electrochemical analytical techniques, including low frequency impedance, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), potentiostatic polarization and Mott-Schottky analysis. The results showed that the corrosion resistance of the TiC-Ti 5 Si 3 nanocomposite film was comparable to that of the monolithic Ti 5 Si 3 film, but was significantly higher than that of uncoated Ti-6Al-4V. The TiC-Ti 5 Si 3 nanocomposite film is thus an attractive candidate for surface protection of components against mechanical and chemical attacks.

“…PVD techniques involving arc deposition are preferred to sputtering techniques because of the high deposition rate and the bond strength of the former [40]. The reduced bond strength in the latter is due to the high residual compressive stresses in the coated substrate resulting from its ionic bombardment during deposition [165,169].…”

The stochastic nature of tool wear during wood machining, owing to the dynamic properties of the biological material and its dependence on various factors, has raised significant industrial and research concerns in recent years. Explicitly, the tool wear is a product of the interaction between wood properties (such as hardness, density, and contamination level) and machining parameters (such as cutting speed, feed rate, and rake angle) alongside ambient conditions (such as temperature and humidity). The objective of this review paper is to provide an overview of recent advancements in the field of wood machining. To begin with, it highlights the important role of wood properties and ambient conditions influencing tool wear. Furthermore, the paper examines the various mechanisms involved in the wood-machining process and discusses their cost implications from an industrial perspective. It also covers technological advancements in the characterization of tool wear and explores the relationship between this parameter and other machining variables. It provides critical and analytical discussions on various methods for enhancing tool wear, including heat treatment, cryogenic treatment, thermochemical treatment, coating deposition, and hybrid treatments. Additionally, the paper incorporates statistical analysis to achieve two objectives. Firstly, it aims to identify the most significant wood property that affects tool wear and establish the correlation between this parameter and wood properties. Secondly, it investigates the effect of heat treatment parameters and carbide characteristics on tool wear as well as their correlation. Lastly, the review provides recommendations based on relevant literature for prospective researchers and industrial counterparts in the field. These recommendations aim to guide further exploration and practical applications in the subject matter.
