Metal Surface Hardening By Boronizing

By Janine Hughes


This is the process through which boron, which is a metal, is introduced into another metal or alloy. It is used to make metal surfaces become hard. Boron atoms are introduced onto a metal surface. This is for the purpose of making it hard to wear. Below is full information concerning boronizing as a type of surface hardening.

The resultant product has the ability to be up to five times more durable than the one which has not been exposed to the same conditions. The main requirement for this process is extremely high temperatures of almost a thousand degrees Celsius. This puts a favorable environment for the process to be successful. The base metal can now be immersed into a mixture composed of Boron.

Not all types of metals use Boron as a source of hardening. Some are compatible with it while others are not. The best fit and the most commonly used is steel. It is reinforced by the method. However, for the treatment process, materials such as nitrogen should not be used since they are not ideal for this process. Nickel materials are favorable for this use too.

The main objective of carrying out this process is to make the initial metal attain new properties. These include being able to withstand high temperatures and be resistant to wear and tear which is common in most subserviced metals. Strong acids are also not able to corrode them as they used to before. This new strength is the most preferred attribute for these metal surfaces.

Most of the processes which take place in the industries usually require high exposure to heat. Temperatures can go up to more than nine hundred degrees Celsius. This requires that metals to be used are those which are able to withstand a lot of heat and a benefit of this process is that strong metals such as these are created.

The metal surfaces that have undergone the procedure can be applied in the making of agricultural tools, drilling tools among others. This is because in such activities, very strong machinery are required. When these considerations are not put in place, the end math will be the occasional replacing of machinery and machinery parts which is quite a costly affair.

The time span of this process is one to several hours when carrying out the process using laser treatment, it does not change the properties of the base material. It has also been tested and proven that the higher the exposure to temperature at a longer period, the thicker the boronized elements are which consequently makes them harder to wear or tear.

In conclusion, it is important to carry out this enhancing procedure in various metals. This is because many companies suffer millions of losses from replacing machinery every now and then due to depreciation. Once this process is carried out on them, they become more durable and hence end up having a longer life span than was the case before.
