A new product "CPC-200 piston ring"

In June, 2017, Riken has obtained the certificate of Winterthur Gas & Diesel Ltd on its "CPC-200 piston ring" for large marine vessel engines, which employs the new surface treatment "CPC-200" for its coating.
The CPC-200 is Riken's originally developed chrome-ceramic surface treatment. It has superior performance in anti-wear and anti-scuffing compared to the conventional chromium platings. Therefore, the CPC-200 piston rings significantly improve engine durability.
Riken has started supplying the CPC-200 piston rings to the Winterthur Gas & Diesel Ltd. licensees (marine vessel engine manufacturers) around the world.

Introduction of High-performance Thermal Spray Coating : RF-2360

Riken produces RF-2312 as a high wear-resistant thermal spray coating for large bore low-speed diesel engine, and it has been gaining a high reputation from our customers. On the other hand, recently, problems of sulfuric acid corrosion caused by slow operation of marine vessels have been closed up. In such severe conditions, a more durable thermal spray coating than the conventional thermal spray coating (RF-2312) is required. Riken has developed a new thermal spray coating "RF-2360" which has a higher durability than that of conventional thermal spray coating in order to meet our customer needs, and received "Certificate of Approval" from MAN Diesel & Turbo.
