In many different applications across a range of different industries, creating a durable, hardened surface that is highly resistant to wear is a key consideration. For any OEM (Original Equipment Manufacturer), finding a company to complete boronizing, also called boriding, will be an important step in finishing components and parts.
The Basics
The process of boronizing can be achieved by several different methods. The most common thermo-chemical process using boron atoms that are exposed to heat to allow the atoms to diffuse into the surface of the metal. Materials suitable for boriding include carbon steels, nickel-based super alloys such as Inconel and Hastelloy as well as tool steels and alloy steels. It is also possible to use the process with cobalt alloys as well as cast and ductile iron as well as other materials.
The Advantages
As there is a true diffusion with the process, boronizing provides a hardening process that will stand up to significant wear and tear. In fact, this will provide up to five times longer life for parts than other hardening options.
* With the use of boriding on parts and components OEMs can expect:
* High temperature resistance on treated surfaces
* High resistance to corrosion from acids
* Decreased friction on parts leading to improved surface wear
* Decreased galling from surfaces exposed to friction
* Dramatically reduced erosion of parts or components
In addition, the use of boriding also provides the option for selective application. This can be effective in cost reduction in the production of the parts or components as only the necessary surfaces need to be processed.
The boride layer created through the diffusion can also be carefully controlled to OEM specifications. It is possible to have the layer as thin as 0.0005 inches to a thickness of up to 0.015 inches. The specific application and the type of wear and tear will be factored in when determining the correct boride layer for the job.
