Basics Relating To Tungsten Carbide Coatings

By Sarah Clark


Before you select an alloy to use for your equipment, it is essential to take into consideration factors like their hardness, wear resistance, toughness, corrosion resistance, edge retention, sharpness, temperature resistance among other things. Tungsten carbide coatings are one of the best alloys or doping materials thus they can be worth giving a try.

There are also some factors that may affect their performance, and they include the kind of binder being used, size of grains, the amount of cobalt that you are using, the mixture of materials as well as that of the grain sizes and the manufacturing techniques among others. It is thus essential to do a thorough research on the materials before purchasing them.

Cobalt is the main binder that is normally used, and once it is added to the grades, they become soft and impact resistant. On the contrary, less amount of cobalt makes the tools to be long lasting, but the part where alloy has been applied can break if it is hit hard. Thus, if cobalt is excessively used, the equipment will be harder, but wearing will also take place very fast.

Normally, smaller grains give the material better wear, and larger grains make the material to have better resistance to impact. If the grains are small and fine, the material becomes so hard. Larger grains, on the other hand, are important in places where there is a severe impact application or wear especially if the equipment is used in drilling or mining. Varying the size of the grain and the amount of cobalt can result in a more robust and harder alloy.

Alloys have so many benefits if they are used due to their hardness. Diamond is the hardest mineral, and the tungsten carbide is thought to fall in second place. Therefore, in the agriculture industry, the alloy is used to coat the tools giving them a longer lifespan thus their performance is increased especially if they are blazed together.

This alloy tends to extend the lifespan of all the wearing parts thus reducing the cost of maintenance. The life of the materials is increased by the hardness that is brought about when the alloy is welded on to the wearing parts. This will prevent the metal from wearing faster thus increasing its life as well as reducing the cost of maintaining the materials.

Another benefit of using this alloy is protecting environmentally sensitive areas. When the alloy is applied to key areas, the design and shape of the parts are preserved making the tool to have the optimum performance for a very long time. If a component has not been welded with the alloy, its edges tend to wear and become rounded. This leads to smearing and compressing of the soil when the part is running through it.

Once the soil is compressed, it can start loosening spoiling the key seedbed thus affecting the early emergence of crops. This can thus lead to poor yields. Therefore, it is essential to use this kind of alloy to protect the wearing parts of agricultural tools so that the soil can be preserved in turn.
