9 Different Types of Corrosion Affecting Materials

Corrosion is the process by which a material deteriorates due to chemical interactions. All materials are subject to corrosive phenomena, but metals are especially prone to corrosion as surface atoms readily oxidise in specific conditions. There are steels designed to utilise oxidation for corrosion resistance (i.e. weathering steel) and other grades with regenerative patinas engineered to reduce surface corrosion (i.e. stainless steel). But few engineering-grade steels can match advanced, corrosion-resistant ceramics in terms of chemical stability. Continue reading

Wear in Industry: Advanced Ceramic Case Studies

Update: Originally posted in 2022, this blog was updated with new context on 27/03/2024.

Careful material selection is essential in sectors using heavy machinery or extreme processing temperatures. Advanced ceramic materials are instrumental in mitigating or diminishing wear in industrial environments. This blog will discuss a broad spectrum of wear mechanisms, highlighting how advanced ceramics outperform traditional ceramics in combating wear. Specific attention will be paid to the role of advanced ceramic materials in resisting abrasive wear, where hard particles remove material from the surface, and adhesive wear, characterized by strong adhesive forces between sliding surfaces. Additionally, we will address how these materials withstand corrosive wear, which involves chemical or electrochemical reactions at the surface.

Advanced Ceramics and Wear Prevention

Industrial processes are dictated by different, often conflicting, needs. Maximising throughput demands minimal downtime. But eliminating downtime is impossible when tools require maintenance to function at optimal levels. However, optimal functionality underlies desired yields and, of course, throughput. There is a cyclical nature to the demands of high-performance industrial components, but there is also a very clear throughline: maximising durability is critical to true quality assurance and profitability. Hence wear prevention is a critical factor impacting a wide range of end-to-end performance parameters.

Understanding Wear and Recognising Different Wear Modes

Update: Originally posted in 2022, this blog was updated with new context on 27/02/2024.

Wear and tear are familiar concepts. But the mechanisms of action underlying these phenomena can be surprisingly complex. Wear is defined as the loss of material from a solid’s surface due to mechanical action exerted by some other solid. It is such a universal process that only organic materials are immune since they can self-replicate and essentially restore surface fatigue. Therefore, every branch of materials science must contend with one or more different wear mechanisms.

Transferring Molten Aluminium Safely with Crucibles & Ladles

Effective manufacturing of finished aluminium products or aluminium castings relies on efficient transferring of large amounts of liquid and solid metal. However, within even the biggest foundries and cast houses there are often instances where operators need to focus on smaller quantities of molten metal and the means of transferring it efficiently and safely.

7 Aluminium Applications & the Foundry Products Enabling Them

Aluminium is an extremely versatile metal with a wealth of applications in a variety of domains, made possible thanks to a range of specialist and technical foundry products that enable them. It is one of the most broadly used metals, second only to iron. This is largely due to its low melting point, malleability at room temperature, and its low density. Aluminium is corrosion resistant and is a good conductor of both electricity and heat.
