“…If the thermal stability of the coating is weak, the service life of the workpiece will be greatly reduced. The subsequent heat treatment of the deposited coating at an appropriate temperature can effectively release the residual stress, reduce the internal defects, homogenize the internal elements, and further improve the performance of the coating [18,19].…”

In order to further improve the mechanical and tribological properties of AlCrTiSiN coating, annealing treatment was carried out in this work. X-ray diffraction (XRD), scanning electron microscopy (SEM), nanoindentation, scratch tester, friction, and a wear tester were used to characterize and explore the effects of annealing temperature on the coating composition, phase component, surface and cross-sectional morphology, and mechanical properties as well as the friction and wear performance of the AlCrTiSiN coatings. The results indicated that after the vacuum annealing the content of amorphous phase decreased and the average size of nanocrystals increased in varying degrees. With the increase in annealing temperature the coating surface became smoother and the cross-section morphology changed little. The coating hardness first increased and then decreased. The adhesion between the coating and substrate decreased after annealing, but the wear resistance was improved. When the annealing temperature was 800 °C, the mechanical properties and wear resistance of the resulting coating were the best. In this case, the coating hardness was 27 GPa, the critical load was 61 N, the friction coefficient was 0.66, and the wear rate was 1.97 × 10−3 μm3/N·μm−1.

Thanks to a considerable number of fascinating properties, titanium (Ti) and Ti alloys play important roles in a variety of industrial sectors. However, Ti and Ti alloys could not satisfy all industrial requirements; the degradation of Ti and Ti alloys always commences on their surfaces in service, which declines the performances of Ti workpieces. Therefore, with aim to further improve their mechanical, corrosion and biological properties, surface modification is often required for Ti and Ti alloys. This article reviews the technologies and recent developments of surface-modification methods with respect to Ti and Ti alloys, including mechanical, physical, chemical, and biochemical technologies. Conventional methods have limited improvement in the properties and/or restriction on the geometry of workpieces. Therefore, many advanced surfacemodification technologies have emerged in recent decades. New methods make Ti and Ti alloys have better performance and extended applications. With requirement of high surface properties in future. Understanding the mechanism in various surface-modification methods, combining the advantages of current technologies and developing new coating materials with high performance are required urgently. As such, incorporation of different surface-modification technologies with high-performance modified layers may be the mainstream of surface modifications for Ti and Ti alloys. . His current research interests focus on the metal additive manufacturing (e.g., selective laser melting, electron beam melting), titanium alloys and composites, and processing-microstructureproperties in high-performance materials.

“…Moreover, previous studies have shown that (Ti,Al,Si)N coatings, deposited by HS‐PVD, had a promising potential for the erosion protection of compressor blades, due to their dense microstructures, smooth surfaces, and a high bonding strength between coating and substrate. [ 31,32 ]…”

Impact Resistance and Properties of (Cr,Al,Si)N Coatings Deposited by Gas Flow Sputtering with Pulsed DC Supply

To increase the erosion and corrosion resistance of compressor blades, hard (Cr,Al,Si)N coatings are used. Physical vapor deposition (PVD) is a well‐known method for the deposition of nitride hard coatings. The application of pulse technique in power supply of conventional PVD technologies like magnetron sputtering shows a great potential for increasing the durability and lifetime of different tools and components. However, one disadvantage of conventional PVD is the line‐of‐sight characteristic. This is eliminated by means of the convection‐driven transport mechanism in high speed physical vapor deposition (HS‐PVD) technology, based on gas flow sputtering. Herein, the influence of gas flow sputtering with bipolar pulsed direct current (DC) power supply on coating properties and impact resistance of (Cr,Al,Si)N/substrate compound is investigated. Thereby, (Cr,Al,Si)N coatings are deposited onto X3CrNiMo13‐4 by HS‐PVD using continuous DC and bipolar pulsed DC supply. Nanoindentation analyses show an increase in indentation hardness using pulsed DC compared with continuous DC. Moreover, the lowest imprint depth and degree of cohesive and adhesive failures are observed in this case. These release a high potential for pulsed power supply in HS‐PVD, resulting in denser morphology, higher hardness and impact resistance compared with DC.
