Galvanic Corrosion: An In-Depth Analysis

What is Galvanic Corrosion? Galvanic corrosion, a relentless adversary in the world of materials and engineering, emerges as a formidable challenge when the wrong choice of metals collides. Many would find it appropriate to secure aluminium components in place with copper alloy bolts. But as is evident in the image above a white area surrounding the central copper alloy bolt appears on the adjacent aluminium. In addition, steel bolts, when improperly matched with bronze plaques, also succumb to galvanic corrosion,

aircraft corrosion 11 areas prone to corrosion

Aircraft Corrosion: 11 Areas Prone to Corrosion

In a previous article, we elaborated on the 11 distinct types of corrosion. If you’ve gone through that piece, you should now be able to differentiate between these forms. However, a question that may linger in your mind is, “Within a large apparatus like an aeroplane, where is corrosion most likely to manifest?” To address this query, this article will explore the top 10 regions susceptible to corrosion. These specific areas prone to aircraft corrosion require more frequent cleaning, inspection,

ways to improve indoor air quality with cleaning and hygiene

Ways to Improve Indoor Air Quality With Cleaning and Hygiene

In the wake of evolving guidelines from esteemed organisations like the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and government agencies such as the Centers for Disease Control and Prevention (CDC), and the World Health Organization (WHO), a fundamental question emerges: How does cleaning impact indoor air quality (IAQ) and how can we improve indoor air quality? Surprisingly, the answer to this question might not be as apparent as one would assume. As we find ourselves on the

Types of Aircraft Corrosion

Types of Corrosion in Aircraft: Aviation MRO

Corrosion poses a significant threat to the integrity and safety of metal structures, particularly in critical applications like aviation maintenance, repair, and overhaul (MRO). Understanding corrosion forms is essential for MRO professionals, as it enables them to implement adequate preventive measures and inspection protocols, ensuring the longevity, safety, and reliability of aircraft components, where various types of corrosion in aircraft can be a significant threat to the integrity and safety of metal structures. This article explores the various manifestations of

Choosing the Ideal Aviation MRO Degreaser: 7 Key Factors

Selecting new cleaning agents for application in aviation maintenance, repair, and overhaul (Aviation MRO) establishments involves significant hazards due to the potential repercussions of an unwise selection. Such a choice could lead to substantial and costly consequences, affecting aircraft operability and safety over the long term, as well as posing risks to human health and the environment. Regulatory fines could also be imposed in cases of non-compliance. Once these challenges have been addressed, should the selected product prove ineffective in

grease lubricant additives and greasing methods

Grease 101 PART 3: Grease Lubricant Additives and Greasing Methods

Welcome to the third instalment of Grease 101. In PART 1 of the series, we provided an overview of grease lubricants, covering aspects like base penetrability, NLGI grade classification, grease drop-point, and dmN factor measurement. In PART 2, we explored lubricating oil and thickeners, elucidating their types and inter-compatibility. This third and final part of the series is dedicated to additives, the third grease lubricant component. We’ll delve into their various types, assess advantages and constraints, and conclude with a

what is hardness of water and how to deal with it

What Is Hardness of Water and How to Deal With It

Water is a fundamental element of life, indispensable for human consumption, sanitation, and industrial processes. Yet, not all water is created equal. As it journeys through the Earth’s crust, minerals and ions, alter its composition, which impacts its quality and usability. One such transformation is the phenomenon known as “water hardness.”   In water chemistry, hardness refers to the concentration of certain minerals, predominantly calcium and magnesium ions, dissolved within the water. While these minerals are essential for human health

Grease 101 PART 2: Grease Lubricant Oils and Thickeners

In the previous article, we gave a general description of grease lubricants, including its base penetrability and how it is measured, classification according to NLGI grade, grease drop-point, dmN factor, and more. We also mentioned that grease has three components: lubricants, thickeners, and additives. In this article, we will be going through the first two components of grease lubricant and the different factors to consider within each component.  Also read: Grease 101 PART 1: Understanding the Basics of Grease LubricantTypes

how to read concentration ratios

How to Read the Concentration Ratio

This comprehensive overview delves into the intricate realm of reading concentration ratio, presenting a clear understanding of weight/weight (w/w) and weight/volume (w/v) units. By offering an analogy that juxtaposes the additive nature of mass with the nuanced behavior of liquids, it illuminates how combining equal volumes of liquids may yield unexpected results due to density disparities. The discourse delves into concentration units—percentages, parts per million (ppm), and parts per billion (ppb)—their conversions, and the pragmatic selection of the appropriate unit

Hepatitis E Virus (HEV): Prevalence, Transmission, and Prevention Strategies

Hepatitis E virus (HEV) is the leading cause of enteric viral hepatitis worldwide. Recently, autochthonous HEV infection has emerged as a significant concern in Europe, as the EFSA reported, making it a global public health issue. Despite its low prevalence overall, HEV varies significantly in different regions, with higher rates observed in developing countries. In Spain, the general population’s prevalence of anti-HEV antibodies is reported to be 1.1% (Echevarría et al., 2014). HEV is a small, spherical virus, approximately 27-34
