3D Microstructure-Based Finite Element Simulation of ColdSprayed Al-Al2O3 Composite Coatings Under Quasi-Static Compression and Indentation Loading
Download2021-07-27
Sayahlatifi, Saman, Shao, Chenwei, McDonald, André, Hogan, James D.
This study developed microstructure-based finite element (FE) models to investigate the behavior of cold-sprayed aluminum–alumina (Al-Al2O3) metal matrix composite (MMC) coatings subject to indentation and quasi-static compression loading. Based on microstructural features (i.e., particle weight...

Computational investigation of the effect of microstructure on the scratch resistance of tungsten-carbide nickel composite coatings
Download2021-08-15
Parsazadeh, Mohammad, Fisher, Gary, McDonald, André, Hogan, James D.
Sliding wear was simulated for tungsten carbide-nickel (WC-Ni) composites with different WC particle sizes and volume fractions under various normal forces. Johnson-Cook and Johnson-Holmquist models were employed to simulate the mechanical behaviour of the Ni and WC phases, respectively. Using...

Parsazadeh, Mohammad, Fisher, Gary, McDonald, André, Hogan, James D.
Abrasive wear was simulated for tungsten carbide-nickel (WC–Ni) composite coatings with different volume fractions of reinforcing particles under abrasive cyclic loading. Using parallelized computing approaches, for the first time in the literature, the effects of reinforcing particle and normal...

High strength particulate aluminum matrix composite design: Synergistic strengthening strategy
Download2021-06-01
Shao, Chenwei, Lo, Calvin, Bhagavathula, Kapil, McDonald, André, Hogan, James D.
Aluminum-alumina (Al–Al2O3) composites with ultrahigh strength were designed by combining dispersion strengthening via the addition of Al2O3 particles and matrix strengthening via in situ strain hardening. Cold spraying additive manufacturing technology was applied to fabricate the composites....

Impact Deposition Behavior of Al/B4C Cold-Sprayed Composite Coatings: Understanding the Role of Porosity on Particle Retention
Download2023-03-22
Farid, Hannaneh Manafi, McDonald, André, Hogan, James David
This study explores the role of porosity in the impact deposition of a ceramic-reinforced metal-matrix (i.e., Al/B4 C) composite coating fabricated via cold spraying. The Johnson–Holmquist–Beissel constitutive law and the modified Gurson–Tvergaard–Needleman model were used to describe the high...

Shao, Chenwei, Li, Haoyang, Zhu, Yankun, Li, Peng, Yu, Haoyang, Zhang, Zhefeng, Gleiter, Herbert, McDonald, André, Hogan, James D.
Nanostructured materials are being actively developed, while it remains an open question how to rapidly scale them up to bulk engineering materials for broad industrial applications. This study propose an industrial approach to rapidly fabricate high-strength large-size nanostructured metal...

On the microstructure-dependency of mechanical properties and failure of low-pressure cold-sprayed tungsten carbide-nickel metal matrix composite coatings
Download2020-08-25
Munday, Guriqbal, Hogan, James D., McDonald, André
This study improves upon understanding of the effects of reinforcing particle content and microstructure on the mechanical properties and failure of low-pressure cold spray fabricated tungsten carbide-nickel (WC-Ni) metal matrix composite (MMC) coatings. Image analyses were performed on scanning...

Jibran, Wania, Hogan, James D., McDonald, André
In this study, a 33 full factorial design methodology was used to analyze the effects of spray parameters on the thickness, hardness, and surface porosity of low-pressure cold-sprayed WC-17Ni coatings. Three levels were selected for the spray parameters included in the design which were the...
