About Teikuro TRD

In May 2002, Teikuro Corporation opened new doors to provide our customers with more flexibility. The properties of TRD coatings makes it vastly superior to anything else available at the present time. TRD greatly increases the tool life in all types of forming and sharing tools used under severe working conditions.

• Dr. Arai: Inventor of TRD
• Why Us?
• Benefits

The Teikuro TRD process was developed at Toyota Central Research & Development Labs. (TCRDL), a project group leaded by Dr. Toru Arai. He had involved in number of the development of high performance tools and wear resistant parts consists of tool steels with a large amount of  fine carbide grains made by special processes including surface treating methods and recognized high performance production tooling  could benefits tremendously to industries. He continued research works for development of wear resistant materials as well as heat treatments and finally succeed to develop carbide coating process completely cover the substrate surface with carbide by the method of salt bath immersion on 1968. The Process is called “Toyota Diffusion(TD) process” in Japan, Thermo Reactive Deposition & Diffusion (TRD) in U.S.A.

TRD process was immediately put into number of practical applications from 1969 in Toyota Motor Company and its group companies and had been used in all industry fields. Results were accumulated as valuable and important information in TCRDL and finally admired as phenomenal invention.

TRD process has been used in 20 different countries and contribute industries as the most superior surface coating last 30 years.
