B4C can deliver the hardest, most lubricous, most wear and abrasion resistant surface treatment commercially available today, without any modification to the dimension or surface finish of the part being treated.
The technology is a cost-effective manufacturing process that fundamentally converts the elemental chemistry of the outer surface of a metal part, producing an extremely hard, porosity free, lubricious, protective layer, capable of withstanding high temperatures, while maintaining the inherent functional properties of the substrate.
With typical coating processes, the coatings are deposited onto the surface of the metal, but with the B4C process, the treatment is actually diffused into the surface of the metal, providing for increased hardness and abrasion resistance without enducing brittleness.
The resulting boron carbide layer has no chance of bond failure and no dimensional change. In essence, the protective layer becomes part of the atomic structure of the part itself.
The resulting coating is harder than tungsten carbide, but lower in friction than Teflon® coatings under loads greater than 150 PSI. This process eliminates bond failures or any compromises between the coating and substrate due to improper preparation, impact from high loads, thermal erosion, corrosion, thermal shock or other external factors.
When applied to high temperature alloys such as Inconel, Stellite, Hasteloy and others, the B4C technology greatly increases the hardness of those materials, from an average of 340-kph to a hardness of over 3,000 kph, maintaining the protective layer and substrate properties up to 3,200 degrees Fahrenheit.
While there is the possibility of reversing core hardness as a result of parts being heat treated in the manufacturing process (otherwise known as reverse hardening), parts receiving the B4C process are easily able to be annealed (or processed through a repeated heat treatment or other reheating process).
The cost effectiveness of hardened manufacturing parts is increased exponentially with more efficient part utilization, fewer part failures, and less frequent part replacements and manufacturing reconfigurations, thus decreasing processing delays and manufacturing downtime. The effective operating lifecycles of products ranging from automotive components to tooling, injection molds to gun barrels, and gears to kitchen products, will be dramatically extended.
