Bor-Fuse ™

Bor-Fuse™ is a thermo chemical surface-hardening process in which boron atoms are diffused into a metal surface to form super hard boride layers. The process is advantageous for any tools or parts where exceptional hardness is required for wear or abrasion resistance.

Bor-Fuse™ is accomplished at temperatures between 850° and 950°C in an inert or reducing atmosphere. This results in the formation of a surface layer of iron boride that has a tetragonal structure and hardness values in the range of VHN100= 2000.

Bor-Fuse™ can be applied by two main methods: powder packing and paste painting. In the powder packing method, the part to be treated is embedded in a powder form of the Bor-Fuse™ chemicals. For treating specific areas, special paste forms of Bor-Fuse™ may be painted onto the specified surfaces. Even the most intricate geometries can be enhanced by this unique process.

Most construction, case-hardened, tempered, tool-making, and chemically-resistant steel types work exceptionally well in the Bor-Fuse™ process. Certain stainless steel and titanium alloys can also be treated. Following the Bor-Fuse™ process, parts may then be coated by any of Surface Technology, Inc.’s unique coatings for additional wear resistance or many other properties such as self-lubricity or light emission.

The Bor-Fuse™ technology is available from STI:

As a coating service from STI’s production facility onto your parts, and
In chemical products from STI for customers to use in their own facilities.

These chemical components are formulated for maximum reliability, convenience, and economy; and are backed up by STI’s first hand practical knowledge of their operation
