“…As the fracture toughness is depended on the applied force, slopes of the P al -1 2 / diagram were considered for comparing the coatings fracture toughness [21,36]. When the applied force was under 500 N, the slope of this diagram for Ti(C,N) single layer coatings was more than the one for TiC single layer coatings.…”

“…They were cleaned with an alkali solution in an ultrasonic bath at 100°C for 10 min. In order to decrease the hardness difference of coatings with substrates and increase the adhesion of coatings to the substrates, a plasma nitriding operation [21][22][23] was performed. Then, the surface hardness of substrates reached to 1000 VHN.…”

“…The working area of the chamber is 500 700 mm (diameter´height) and a pulsed-DC power supply was used to trigger the plasma. Details about other experimental conditions were mentioned in the other our research [21,24,25]. In multilayer coatings, the TiN layer was firstly deposited due to have a better adhesion to the substrate [26].…”

Mechanical properties of multilayer and multicomponent coatings were investigated in this paper. Titanium nitride/titanium carbide (TiN/TiC-n) multilayer and Ti(C,N) multicomponent coatings were prepared on the surface of AISI H13 hot work tool steel by the pulsed-DC plasma assisted chemical vapor deposition (PACVD). The microhardness, the toughness, the wear loss, and the friction coefficient were examined by Vickers hardness test and the pin-on-disk wear test. The optical microscopy was also used to examine worn surfaces and to characterize wear mechanisms. The results obtaiond show that multilayer coatings of TiN/TiC-10 have the lowest friction coefficient (as 0.2) and wear loss, the highest toughness (as 17. 7 MPa m 1 / 2 × ) and microhardness (as 3150 VHN) among those values for multicomponent Ti(C,N) coatings and other multilayer coatings.

“…Particularly, the increase in hardness and load-bearing capacity brought about by the deposition of such films has been attributed to the presence of interfaces between the different layers, which act as barriers to dislocation motion. Therefore, as the number of such interfaces increases, a concomitant increase in the mechanical properties and performance of the multilayer coated system has been observed [1][2][3][4][5][6][7][8][9][10][11][12].…”

Thin Solid Films, Elsevier, 2015, 583, pp.177-193. 10 The evaluation of the elastic response of coated systems under indentation loading represents a crucial issue, which determines the behavior of such systems under tribological applications. Although a number of models have been proposed in the literature for the description of the change in the composite modulus with indentation depth, as well as for the determination of the elastic modulus of monolayer coatings, only few works address the analysis of multilayer coatings. The present work proposes a general methodology, which allows the modification and extension of the models employed in the analysis of monolayer coatings, for the study of the elastic response of multilayer coatings. Bull for a bilayer coated system. It has been shown that the different models analyzed are able to provide a satisfactory description of the experimental data, although the quality of the fit depends on the number of material parameters involved in each model. The mean square error of the fit is employed for conducting a comparison between the models.

Abstract. In this paper, the TiN-based of CrTiAlN multiple composite coating were deposited on die steel substrates .The phase structure, chemical composition and morphology of the coating were tested by XRD, SEM and EDS respectively. The adhesive strength between film and substrate and microhardness about the coating were tested by Rockwell hardometer and Vickers hardometer. The results showed that the coating surface morphology of CrTiAlN had become tightly clustered granular particles, and the section morphology had a structure with columnar crystal. The main crystalline phases of CrTiAlN coating were consisting of TiN, CrN, Cr 2 N and so on. Rockwell indentation test showed that it had good bonding force between the CrTiAlN coating and the die steel substrates.
