“…This is because the semi-coherent interface structure between layers in Ti/Zr multilayer films produces strong internal stress due to lattice mismatch. This stress can significantly change the lattice constant when the layer is relatively thin [77]. The variation in stress in multilayer films with different layer thicknesses can also be observed from the shift of the peak position in XRD images, as shown in Figure 8.…”

“…The main reason is that as the layer thickness increases, the in-plane compressive stress is gradually enhanced during the deposition process, which leads to peak shifts. For the Ti/Zr multilayer films in Figure 8b, the Ti (0002) and Zr (0002) peaks deviate from their standard Bragg angles in the opposite direction when the layer thickness decreases to 5 nm, which indicates that there are tensions and compressive stresses in the Zr and Ti layers, respectively [77]. This is because the semi-coherent interface structure between layers in Ti/Zr multilayer films produces strong internal stress due to lattice mismatch.…”

“…It can also be observed from the SAED patterns that the two sets of bright diffraction spots combined with weak diffraction rings become closer with decreasing layer thickness and overlap when the individual layer thickness is below 4 nm. In Figure 8a,b, the superlattice structure is shown in Cu/W multilayer films with layer thicknesses of 10 nm or less and Ti/Zr multilayer films [77] with a layer thickness of 5 nm. In Figure 8c, the V (110) and Cu (111) peaks of Cu/V multilayer films are well separated when the layer thickness is 50 nm but they overlap when the layer thickness decreases to 2.5 nm [75].…”

Multilayer films with high-density layer interfaces have been studied widely because of the unique mechanical and functional properties. Magnetron sputtering is widely chosen to fabricate multilayer films because of the convenience in controlling the microstructure. Essentially, the properties of multilayer films are decided by the microstructure, which could be adjusted by manipulating the deposition parameters, such as deposition temperature, rate, bias, and target–substrate distance, during the sputter process. In this review, the influences of the deposition parameters on the microstructure evolution of the multilayer films have been summarized. Additionally, the impacts of individual layer thickness on the microstructure evolution as well as the irradiation behavior of various multilayer films have been discussed.

Aluminum rich nitride coatings are often used to protect cutting tools and prolong their service life. In this work, a preoxidation technique and duplex coating design were combined to further improve the bearing capacity and heat resistance of cutting tools. The Al-Cr-Si-N, Al-Cr-Si-O-N, and Al-Cr-Si-N/Al-Cr-Si-O-N duplex coatings were developed by arc ion plating, respectively. The morphology, phase constituents, mechanical and tribological properties of the coatings were characterized and tested by SEM, XRD, a micro-hardness tester, scratch tester, and tribometer. The results showed the coating became more compact and smoother after oxygen doping. However, the Al-Cr-Si-N coating presented the best mechanical properties and tribological behaviors. Its hardness and critical load showed the highest values, which were about 4000 HV and 81 N, respectively. A friction coefficient of 0.67 and wear rate of 1.4 × 10−3 μm3/N·mm were also the lowest values in the study. The three coatings were deposited on the same solid carbide end mills and performed the cutting tests under same conditions. By comparison, the Al-Cr-Si-N coated tool presented the longest tool life and minimum cutting force when cutting C1045 medium-carbon steel. After 90 min of dry milling, the width of the flank wear band (VB) of the AlCrSiN coated tool reached 135 μm, which was much lower than that of the other two coated tools.
