In the field of mechanical engineering, conventional methods of wear protection such as induction hardening, laser hardening, case hardening, nitriding, PVD-coating, flame spraying, and build up welding do not offer sufficient protection. In these cases, boronizing offers a superior solution to improve mechanical properties significantly.
Wear protection by boronizing for mechanical engineering
The development of engines is one of the most significant progresses of our modern society. Engines enable efficient methods of production, open up new possibilities of energy generation and, as a result, serve humanity. Mechanical engineering and construction has always and will always be characterized by their endless innovations and improvements. Unfortunately, even contemporary and up-to-date engines struggle with wear. When new technology are accessed, new problem areas arise, namely deterioration and wear.
To meet the various demands of wear protection, boronizing with the BoroDur treatment is required. BoroCoat diffusion layers display hardness denominations of up to 2800 HV while also showing great thermal persistency. Materials that are hardened by our patented BoroDur and BoroCoat treatment exhibit excellent wear resistance.
In which areas can boriding minimize wear?
There are many possibilities for the application of boriding layers in mechanical engineering. The high thermal persistency of borided surfaces predestines BoroCoat for the application in engine and turbocharger technology, as well as power plant construction. The superior hardness of the generated borides, and their excellent properties of resistance against abrasion and surface spalling, are used in the area of harvesting machines. Furthermore, borided components display outstanding resistance against cold welding of metallic friction partners. Cavitation wear can occur in pumps and turbines and can be prevented by boriding surfaces of the affected parts. Additional cases of applications can be found in incineration plants, piping systems, conveyors, and shredder plants.
Which materials can be treated by BoroDur and BoroCoat?
One of the major advantages of wear protection by boriding is the broad range of treatable materials. The majority of metals, that are utilized in mechanical engineering can be treated with our special boronizing treatment. Steels, cast iron, nickel based alloys, stainless steels, heat-resistant steels, tool steels and carbide metals are eligible for treatment. Moreover, our methods are extremely flexible, which is why bulk material and single, large components can be hardened as well.
