Development of Next Generation High Entropy Alloy Coatings for Extreme Environments

The integrity and performance of hydraulic components in the maritime sector may be altered due to extreme environmental conditions that result in wear and corrosion. The industry in Canada spends around $0.92B per annum for maintenance (around 69% of GDP) to improve component service life. Therefore, materials that can sustain high life during extreme operating conditions are in demand. Next-generation advanced materials, known as high entropy alloys (HEAs), have gained attention of the scientific community by breaking the bottleneck of conventional alloy design strategy.

Design and Optimization of the product platform for AIS mobile robots

AIS Inc. is at the forefront of developing practical mobile robots for various markets. Mobile robots are considered as very complex systems comprising of hundreds of interacting components in complex system architectures. Developing such complex robotic systems, particularly in large scale, requires a coherent collaboration and engagement on various specialized areas. All of the complex products which are under development in AIS, have many Common Elements (CE) both in their system anatomy (e.g.

Connecting atom-scale bentonite clay models to macroscale mechanical and transport models for spent nuclear fuel storage - Year two

Bentonite is a naturally occurring clay containing montmorillonite, a smectic clay mineral that has a high cation exchange capacity and swells upon contact with water. The swelling capacity of bentonite limits movement of water which makes it an attractive candidate to be used as an engineered barrier system to protect used nuclear fuel containers that are stored in deep geological repositories. The Nuclear Waste Management Organization is responsible for Canada’s implementation of the plan for the long-term care of nuclear-spent fuel produced by Canadian nuclear reactors.

Vison-based frameworks for automated robotic machining of aerospace composite panels

Canada is a global leader in the aerospace manufacturing industry. Canadian companies produce complex assemblies and system solutions including carbon fiber composite panels used in the body of airplanes. Manufacturing of such panels requires a significant number of operations such as trimming, drilling, and abrasion. Currently, some of these operations are performed manually, which is labor-intensive and time-consuming. The overarching goal of this project is to develop automated and accurate robotic systems for aerospace composite manufacturing applications.

High heat flux microprocessor cooling using binary fluid mixtures

As the heat fluxes produced by modern high-performance microprocessors continue to rise, so too must the effectiveness of the removal of these fluxes. Accordingly, a large amount of research has focused on developing techniques to enhance cooling in computer systems. A novel method of doing so involves replacing the single-phase liquid or two phase-liquid vapor coolants typically employed in such systems with binary fluid mixtures.

Development of a new generation of neurovascular device for the treatment of fusiform cerebral bifurcation aneurysms using CFD modeling and virtual simulation of stent crimping into a catheter

Cerebral aneurysm (CA), is an abnormal dilation of the cerebral arterial wall, which accounts for more than half a million deaths each year worldwide. Flow diverters (FDs) represent one method recently developed in treating CAs.

Metamaterials toolbox:Tuning heat flow at will in the Si-based materials at nano- and mesoscales

Heat management in semiconducting nanomaterials requires the design of engineered artificial structures, known as metamaterials, where thermal properties can be tuned almost at will by microstructural modifications. Testing a broad range of nanostructures for the particular device applications, with predictive behavior, is a grand challenge especially because of the difficulties associated with the experimental synthesis of the pristine samples, their char- acterization and property calculations.

NANOSTRUCTURE COATED PBO (ZYLON) FIBERS FOR LIGHTWEIGHT AND HIGH-STRENGTH STRATOSPHERIC APPLICATIONS

The idea of airships to have blimps carry heavy loads into remote areas, has been discussed for years in Canada. Such a futuristic concept has recently been brought into reality by Sceye Inc. which created a new class of airship capable of flying the unchartered stratosphere. However, Zylon (PBO) fibers, the main component of airship envelope, typically suffer from environmental degradation when exposed to high humidity, ultraviolet (UV), and ozone in the harsh operation environment.

Development of a thermal spray wear-resistant coating for abrasive concrete applications

Mechanical wear and chemical corrosion are the two main dominant factors that limit the service life of industrial machinery. Wear and tear of tools and equipment are significantly intensifying due to the increasing demand for superior efficiency, productivity, and throughput of industrial apparatuses. Since the surface of the materials is more exposed to abrasive wear and erosion, surface protection is considered an effective and economic approach to improve the service life of machinery components.

Numerical simulations of cavitation in oil pump and bearings for automotive applications

The hydraulic circuit, including pumps and bearings, has important application in automotive industry. The hydraulic circuits inside the engine block are often affected by the cavitation phenomenon. Cavitation can cause pressure fluctuation inside the fluid circuit and considerably affect the engine workability, durability, and efficiency. This proposal will address the cavitation by modeling the oil flow in vane pumps and bearings and analyze the cavitation using 3D CFD software PumpLinx? (by Simerics Inc.) and 1D GT Suite.
