After thousands of kilometres of daily driving, even the cleanest engine will most likely be covered with crud. Oil leaks and grime combine to form a greasy coating on the outside of the engine. Now imagine how much dirt and grease must be cleaned off in trying to restore an old car. If you’re into collecting and restoring vintage cars, glass beading is a relatively inexpensive yet highly effective way to clean the internal parts of the vehicles, like the flywheels, cams, piston conrods and crankcases.
Typically, glass beading for any metal surface is a form of high-pressure cleaning, done in a less-damaging system than typical abrasive blasting. In the U.K., this is usually performed by professional anodisers, like Badger Anodising (Birmingham) Ltd, which offer specialised cleaning, finishing and peening services that will leave all metal parts shiny and in a remarkable state.
If you are someone who’s wholly interested in the properties of metal and their suitability for various tasks, you may have already come across the concept of colour anodising for aluminium and other metals. Essentially, this is a process of adding a dye to an anodised metal before it is sealed. Aluminium is the most common metal that undergoes such treatment, but there are many other suitable metals like magnesium and titanium.
While anodising has numerous benefits, adding colour is mostly done to help distinguish parts and provide an aesthetically pleasing appeal to metal products for consumers. For example, titanium is a very good option for use in medical implants because it is extremely resilient, lightweight, and biocompatible. Adding an anodised colour to it allows for fast and easy identification for the various implant parts during surgery.
Aluminium alloys have been one of the widely used metal materials in many industries, including art and architecture. To create a more durable substance, aluminium is normally treated with metal finishing techniques such as anodising, bead blasting, and other pre-treatment methods.
Among the techniques, anodising is most preferred by many manufacturers for it creates a durable finish with a hardness level second to that of diamond. Anodising aluminium involves an electrochemical process that strengthens the metal surface by adding a layer of protective anodic coating. After the entire process, the anodic coating becomes part of the metal, but it has a porous structure that allows for enhancement procedures such as inorganic colouring, which opened doors for many decorative functions.
Advancements in the aerospace industry have urged the importance of safety in the materials used to build the vehicles. To ensure this safety, many manufacturers are giving greater attention to the final stage of their production, namely: through higher quality of finishing metal surfaces.
One of the most effective and popular metal polishing techniques used today is anodising, wherein the aluminium alloy is processed to become more durable and corrosion-resistant. Anodised products also allow added secondary treatments like dyeing and etching for aesthetic purposes.
When we think of something made of metal, we often picture something that’s quite indestructible. Army tanks, military fortifications, battle armour—all of them elicit the same aura of invincibility simply because they’re made of strong, thick metal. But alas, science dictates that what most people would deem invincible is not exactly so. Enter the fascinating yet damaging process of corrosion, which has made metal finishing processes like polishing aluminium and other types of metal a relevant occurrence today.
First of all, it helps to know what corrosion is all about. In general, corrosion is a natural process that breaks down several types of metals. Corrosion happens more commonly among anode metals, or those that gives up electrons whenever they come in contact with a liquid electron conductor, which is known as an electrolyte (i.e. water), oxygen, and a cathode (a substance which accepts electrons).
Non-stick cookware were specifically invented since there’s perhaps nothing more infuriating than having food stick to the pan when preparing a meal. While people have devised quite a few ingenious solutions to this (spraying the pan with olive oil, for one), it’s obviously much better to avoid using that traditional non-stick pan and opt for better alternatives.
The concept of non-stick cookware is wonderful, sure, but the reality of using them is more dangerous than what people think. This is because traditional non-stick cookware does its wonders with Teflon—a synthetic chemical known to emit toxic fumes if heated in the right temperatures. Exposure to such noxious gases can lead to the so-called “polymer fume flu” that causes nausea, chills, fever, and headache. Fortunately, homeowners have a wide collection of alternatives at their disposal.
