The effect of residual stresses in functionally graded alumina–ZTA composites on their wear and friction behaviour

Mechanical Behavior of TiN/TiC-n Multilayer Coatings and Ti(C,N) Multicomponent Coatings Produced by PACVD

“…The increase in the number of layers in multilayers coatings resulted in the decrease of the friction coefficient, as mentioned by other researches [29,50]. The hardness, the fracture toughness, the structure, the composition and other properties of coatings had effects on the friction coefficient [51]. As is shown, the reduced thickness of each layer in multilayer coatings caused the increase in the hardness and the fracture toughness.…”

Corrosion Resistance of 304L SS Spray Coated with Zirconia Nanoparticles

“…As a result, the tensile stress in films fails to protect the substrate from corrosion in adverse environment. Consequently, the residual stress has a significant impact on mechanical properties [24], fatigue strength [25], wear and fracture properties [26,27] of thin films. The toughness and wear-resistance of nanostructured zirconia thin film coated on 304L SS is investigated through Nanoindentation technique.…”

“…FGMs are referred to as a class of advanced composites (Hvizdoš et al, 2007;Suresh and Mortensen, 1997) that operate by varying the microstructure of materials that have different mechanical properties in the layers, for instance, an object with a tough core and a hard surface (Mehrali et al, 2011;Novak et al, 2007;Put et al, 2003). A large range of processes for the production of FGMs are available, such as centrifugal that can be bonded together via the process of sintering in order to form high-performance ceramics that can be used in applications that require high-endurance materials that can withstand high temperatures while retaining their strength, hardness, frequency, biocompatibility, corrosion resistance, and also maintaining a self crack-healing ability (Ando et al, 2004;Casady and Johnson, 1996;Kotzar et al, 2002;Rosenbloom et al, 2004;Thompson et al, 1995;Yakimova et al, 2007).…”

“…However, the restricted strength of this material presents an inappropriately high risk of fracture (Novak et al, 2007). The objective of this study was to vary the compositions of SiC and ZrO 2 (zirconia) in order to produce a material that had a tough core and hard outer layers and thus improved the properties of Al 2 O 3 /ZrO 2 FGM (Hvizdoš et al, 2007;Novak et al, 2007;Vleugels et al, 2003). A 2-butanone-based suspension was used for EPD and both homogeneous and functionally graded ceramic-ceramic, Al 2 O 3 , SiC, and ZrO 2 , where the external layer was SiC and Al 2 O 3 and the core layers were a homogeneous SiC, Al 2 O 3 , and ZrO 2 composite.…”
