Metal Surface Hardening By Boronizing

By Janine Hughes


This procedure manly involves having the main objective of making other metals or mixture of metals to be hard. It is done using atoms from boron. When it is made harder, then it becomes stronger and is able to withstand different kinds of conditions including the ability to resist wear. The following information is all about boronizing which is basically using boron as a component of metal hardening.

This process makes the materials be able to last up to five times longer than when they were subjected under other types of hardening. This method is also known as boriding and it can be achieved in a number of ways and this includes packing the piece of metal in a boriding mixture and heating it to a temperature of nine hundred degrees Celsius.

One of the most common metals whereby this procedure is applied is in steel. This metal corrodes very fast if not treated in advance. Alloys of nickel can be used during the treatment process and others like aluminum are best avoided because they are not fit to be applied in this process. Steel alloys can also be added to the list of materials used during the treatment phase.

Once this process is done, there are a number of properties that the new material now attains. These include improved hardness; they then become hard to wear out. They are also able to sustain a high exposure to heat and they are also less likely to be affected by strong acids. To add on to this, friction is also able to be sustained. This makes machinery be able to last longer and be in a better condition.

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.

There are a number of application areas for such kind of materials. To begin with, the agricultural sector deals with a lot of machinery especially the tractors which are usually used for farming and harvesting. Its important that such are made of strong durable metals which do not wear easily. This technique can also be applied to those equipment used for drilling oil in the oil fields.

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.
