“…The AlTiSiN/Inconel sample presented the highest value of G c = 321.5 J/m 2 , as seen in Table 7 . The range of values was similar to those previously report by other researchers for similar hard coatings [ 57 , 58 , 59 ]. Of all the studied systems, AlTiSiN/steel presented the higher adhesion energy.…”

The objective of this study was to explore the mechanical properties of AlCrSiN and AlTiSiN coatings deposited on Inconel and steel substrates after thermal treatments of 500 °C and 800 °C. Nanoindentation was used to measure the hardness and elastic modulus of the coatings, and microindentation was used for observing the contact damage with Hertzian contact loadings. Microscratch and Mercedes tests were used to evaluate the adhesive strength between coating and substrate with both progressive and static loads, respectively. The surface damage was inspected by optical microscopy and scanning electron microscopy (SEM). Focus ion beams (FIB) were used to mill the cross-sections in order to detect the extent and mode of failure. The results show that AlCrSiN coatings and Inconel substrates exhibit better mechanical performance, even after thermal treatments.

“…Calculation of adhesion energy followed the method from the previous study by S. J. Bull et al, and the values of G c were similar to previous research on similar coatings such as CrAlN and AlCrSiN [34,40,43,44]. Figure 5 presents the SEM images after the contact damage tests at a series of normal loads of 98 N, 196 N, and 294 N. For the sample of AlCrSiN coating deposited on the WC-Co substrate, the coating does not show any cracking.…”

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

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.

“…Plastic deformation of deposited surface also depends on the value of strain hardening exponent (see Table 1), and as we can see, multilayer Cr 2 O 3 /TiAlN coating (0.46) has a higher value of n compare to single‐layer Cr 2 O 3 coating (0.33). Higher attributes of fracture toughness, that is, H i /E c (resistance to wear) and

H_i^3/E_c^2

(resistance to plastic deformation) also, confirm the resistance of deformation and wear of the coating 42–44 . Further, the ratio of elastic modulus was also determined to evaluate the wear of the coated surface.…”

“…Higher attributes of fracture toughness, that is, H i /E c (resistance to wear) and 𝐻 3 𝑖 ∕𝐸 2 𝑐 (resistance to plastic deformation) also, confirm the resistance of deformation and wear of the coating. [42][43][44] Further, the ratio of elastic modulus was also determined to evaluate the wear of the coated surface. It was suggested in the previous literature 4 that a ratio of elastic modulus of >1.3 indicates stronger crack inhibition in coatings.…”

TiAlN film was deposited on Cr2O3‐coated plasma‐nitrided DAC‐10 tool steel to obtained multilayer Cr2O3/TiAlN coating layer using cathodic arc deposition technique. The structural make‐up of the coating was characterized using Atomic Force Microscopy (AFM) and X‐ray diffraction methods, and the mechanical properties were evaluated using nanoindentation and nanoscratch test. The structural phases of the coating indicated the presence of crystalline CrO structure and cubic TiAlN phases. The coating showcased improved hardness (38 GPa), elastic modulus (387 GPa), and adhesion along with appreciable H/E (0.09) and H3/E2 (0.366 GPa) attributes. Further, friction‐induced wear behavior of the coating was investigated against steel and Al2O3 counterbodies under dry sliding conditions. The wear behavior of the coating was greatly influenced by its hardness and deformation properties and frictional behavior of the counterbodies. More spikes and fluctuation were observed in the frictional curve against Al2O3 counterbody attributed to the emanation of TiO2, Cr2O3, and Al2O3 compounds due to dry sliding leading to the formation of flakes and delamination induced debris. Against the steel counterbody, the coating mainly formed a typical smooth glossy surface ascribed to the formation of Fe2O3 compound on the worn surface.
