Jun 10, 2021 · Phase for Enhanced Tribological Properties microstructures and mechanical properties of blends, we found that with increased content of PP, the wear mechanism of blends varies from abrasive wear, fatigue wear, to adhesion wear as the

Influence of Ag Content on the Microstructure, Mechanical

The microstructure, mechanical properties and tribological performances were investigated. The results showed that ZrN-Ag films were composed of face-centered cubic (fcc)-ZrN and face-centered cubic (fcc)-Ag. With the increase of Ag content, the hardness of ZrN-Ag composite film increased rapidly and then decreased rapidly. Mechanical Properties of Materials with Nanometer Scale Oct 31, 2004 · @article{osti_833870, title = {Mechanical Properties of Materials with Nanometer Scale Microstructures}, author = {Nix, William D}, abstractNote = {We have been engaged in research on the mechanical properties of materials with nanometer-scale microstructural dimensions. Our attention has been focused on studying the mechanical properties of thin films and interfaces and very small

(Ref 9) found that the wear resistance of cold-sprayed iron (Fe) Al alloy coating was higher than that of heat-resistant 2520 stainless steel even under a working temperature of 800 C. Bakshi et al. (Ref 10) investigated the tribological properties of cold- Mechanical, Microstructural and Tribological Properties of Oct 02, 2008 · The coating microstructures were studied using scanning electron microscopy (SEM), Raman spectroscopy, and atomic force microscopy (AFM); the mechanical properties were characterized using nano-indentation; the tribological properties were studied using a pin-on-disc tribometer; and the surface energy (contact angle) was measured.

Microstructure, Mechanical and Tribological Properties of

The NiAl/Cr (Mo,Dy) hypoeutectic alloy was fabricated by rapid solidification. The microstructure and mechanical properties as well as tribological properties for the alloy at different temperatures were investigated. The results revealed that the rapidly solidified NiAl/Cr (Mo,Dy) hypoeutectic alloy was composed of primary NiAl, fine NiAl/Cr (Mo) eutectic lamella, Ni5Dy phase and Cr7Ni3 Optimization of mechanical and tribological properties of Nov 05, 2019 · The aims of the study were to evaluate the influence of microstructures of a SiO2-Al2O3-K2O-CaO-P2O5 fluorapatite glass-ceramic on its mechanical properties and tribological behaviors, and to improve the comprehensive performance by adjusting content and sintering process.

The aims of the study were to evaluate the influence of microstructures of a SiO 2-Al 2 O 3-K 2 O-CaO-P 2 O 5 fluorapatite glass-ceramic on its mechanical properties and tribological behaviors, and to improve the comprehensive performance by adjusting content and sintering process. The glass-ceramics were fabricated by sintering method with Microstructural, Mechanical, and Tribological Properties Jan 28, 2021 · In this study, Mg-3Al-1Sn-1Nd-Mn alloy was produced by low-pressure die casting method and homogenization heat treated (HHT) at 400 °C for 16 hrs. Microstructural characterization of the alloy was done by XRF, XRD, LOM and SEMEDS analyses. The microstructure of the alloy was composed of -Mg, Al2Nd and Al11Nd3 phases. Hot rolling was applied to the HHT alloy at two
