Corrosion Resistant Ceramics Case Studies

Posted on by

Corrosion-resistant ceramics are often mandatory in harsh environments, namely in the oil and gas industries. This is because ceramics provide high levels of corrosion and thermal resistance and have outstanding wear, and these fundamental properties make them more suitable than traditional metal components.Continue reading→

Are Ceramics Corrosion Resistant?

Posted on by

Ceramics are the preferred materials for use in harsh environments because they are highly resistant to corrosion and wear. Aside from being corrosion and wear-resistant, advanced ceramics can also withstand high temperatures, pressures and other extreme conditions. Throughout this blog post, we will look at how corrosion-resistant ceramics are used in the oil and gas industries and what benefits this provides.Continue reading→

9 Different Types of Corrosion Affecting Materials

Posted on by

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→

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

Posted on by

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

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.
