The process wherein boron gets introduced to other alloys or metals is a very complicated process. The type of hardening surface like boronized tubing is a process wherein boron atoms get diffused in metal component surfaces. The surface will result to metal borides, like iron, nickel, and cobalt borides for example.
As such pure type of materials, the borides would then have extreme higher hardness and resistance to wearing. The properties favorable are the ones manifested even when they have smaller fractions of solid bulked. The metal parts of boron are extremely resistant to wears and would often even last two or even five times more compared to heat treatments which are conventional like hardening, carburizing, and even hardening inductions.
Most steel surfaces would have layers of hardness which would range from one thousand two hundred to a thousand six hundred of its hardness scale. The super alloys which are nickel based typically will contain at least one thousand seven hundred to two thousand three hundred in the scale. This method should be achieved in varying ways and processes.
However, the metal piece which is quite common is actually packed with mixtures and heat that rises up to nine hundred degree Celsius. Typical mixtures would consist of diluted powders with other materials refractory. This type of process should convert some iron that consists of at least two types of phases.
They will get concentrated very near to its surface, and the depths of layers could range varyingly depending on the selections of base materials and including the treatment too, that gets used often on steels as well. However, they are only applicable to differing varieties of cermet and alloy materials.
Wide ranges of suitable materials for treatments will include, alloy steels, carbon steels, tool steels, and super alloy from nickel, and also cobalt alloys. The said materials would not compatible with this process are stainless steels, silicon, nitrogen, and aluminum containing grades. It would give the material desirable properties of the following. For example, improved hardness and wear resistance to add with.
Another property gained is thermal stability, corrosion resistance from acids, and reduced friction coefficient as well. You might want to include increased resistance capability on galling and cold welding. What is quite possible for this is combining other treatments of heating as well like induction and hardening in order to create deeper layers and hardness of core.
Furthermore, you may call this as one process which is thermochemical hardening to surfaces. There actually are no mechanical interfaces between complex ones and its substrate as this is one true process of diffusion. The layer case resulting is slipper and a hard surface which is capable to perform at very high temperatures.
Practically, all materials ferrous could undergo this as well. However, you must take note of this, the higher content of the alloy elements, it could even have a slower rate of diffusion. The process is then used in improving performance and life of the metal components. Such benefits you will get is to strengthen resistance to wearing.
