Small but terrible

Have you ever wondered what 5 μm looks like? To put it into perspective, the average size of our hair strands is 75 μm. In our laboratory, we've engineered mechanically alloyed particles with diameters much smaller than that of a hair strand. Utilizing the cold spray process, a solid-state deposition technique below the particle’s melting temperature, these “small but terrible” materials are accelerated and impacted into a substrate, eventually creating a coating. But what purpose does this coating serve? Essentially, it acts as a shield, safeguarding the substrate against harsh environmental conditions by improving its surface mechanical properties. This enhancement enables the component to endure its intended application for an extended period. Therefore, when effectively bonded to the substrate, these particles play a crucial role in holding the port preserving the integrity of the main material. At UNB, we are dedicated to advancing materials science by developing novel materials and unlocking their potential. Our research efforts directly contribute to extending the lifespan of our critical components ensuring safety and maximizing value for every penny.
