“…Hardness values measured for the uncoated WC-TiC-Co samples are similar to those reported in other studies [35][36][37]. The results of hardness and H 3 /E 2 reported for the AlCrSiN, instead, are similar and even higher than those presented in other research, such as AlCrN/AlCrSiN coatings deposited on high-speed steels [38], carbide cutting tools coated with TiAlN/TiSiN and monolayer AlCrSiN ceramic films [39] or AlCrSiN and AlCrSiON deposited on cemented carbide substrates [40]. The higher values of H 3 /E 2 are an indicator of a higher resistance to plastic deformation and improved wear resistance of the coating if it is compared with the uncoated WC-TiC-Co.…”

This study aims to investigate the improvement of the tribocorrosion properties of WC-TiC-Co substrates by coating them with hard coatings such as AlCrSiN using cathodic arc deposition. WC-TiC-Co is commonly used in the fabrication of machining and cutting tools; however, there are some materials such as titanium or stainless steel that are difficult to work with; furthermore, in aggressive environments or under high temperatures the performance of the machining tools can be affected, and a failure may occur. This coating is intended to ensure the correct performance of the tools in any conditions. The coatings were characterized by glow discharge optical emission spectroscopy (GDOES), scanning electron microscopy (SEM) and X-ray diffraction (XRD). Tribocorrosion, tribology and corrosion tests were performed to evaluate the tribocorrosion properties of the samples. Furthermore, mechanical and adhesive properties of the coating were studied using scratch and nanoindentation tests. The results showed improved tribocorrosion properties in the samples combined with good adhesive and mechanical properties. These results show the possibility of using these coated materials in the most demanding cutting and machining applications.

“…Although the mechanical properties of these coatings have been studied before [15], information about mechanical behavior when the coatings are deposited on different substrates is scarce. Performance of tool materials is governed by both the coating and the substrate, which may result in very different performances even for the same coating if the substrate is different.…”

Comparative Study of Mechanical Performance of AlCrSiN Coating Deposited on WC-Co and cBN Hard Substrates

et al. 2023

The objective of this study is to explore and compare the mechanical response of AlCrSiN coatings deposited on two different substrates, namely, WC-Co and cBN. Nano-indentation was used to measure the hardness and elastic modulus of the coatings, and micro-indentation was used for observing the contact damage under Hertzian contact with monotonic and cyclic (fatigue) loads. Microscratch and contact damage tests were also used to evaluate the strength of adhesion between the AlCrSiN coatings and the two substrates under progressive and constant loads, respectively. The surface damages induced via different mechanical tests were observed using scanning electron microscopy (SEM). A focused ion beam (FIB) was used to produce a cross-section of the coating–substrate system in order to further detect the mode and extent of failure that was induced. The results show that the AlCrSiN coating deposited on the WC-Co substrate performed better in regard to adhesion strength and contact damage response than the same coating deposited on the cBN substrate; this is attributed to the lower plasticity of the cBN substrate as well as its less powerful adhesion to the coating.
