Diamond-like Carbon Film for Bearing Parts and Its Mass Production Technology

摘要

Active efforts have been made to create environmentally friendly products in the automobile market. Under this circumstance, parts that make up an automobile need to maintain their functions in harsh environments, requiring even higher durability than ever before. To meet this challenge, we have developed a diamond-like carbon (DLC) film that has an excellent rolling fatigue resistance for bearing parts. We also started the mass production of the DLC film coating for bearing parts by overcoming production technology challenges, and achieved both mass productivity and cost efficiency.
