Autor: Kenji Ohara, Kiyoshi Hanyuda, Yasushi Kawamura, Kentaro Omura, Imari Kameda, Noritsugu Umehara, Hiroyuki Kousaka

Publikováno v: Tribology Online, Vol 12, Iss 3, Pp 110-116 (2017)

Wear of DLC coating has been great concern in DLC/Steel sliding surface lubricated by molybdenum dithiocarbamate (MoDTC) containing lubricants. However, in order to design lubrication system with DLC and MoDTC, the mechanism of this issue is needed t

The Development to Control Simultaneously Viscosity and Separation Temperature of a Two Phase Lubricant for Practical Use

Autor: Kumiko Kamata, Yasushi Kawamura, Ryuji Maruyama, Eiji Nagatomi, Hiroyuki Tazaki

Publikováno v: Tribology Online, Vol 11, Iss 1, Pp 24-33 (2016)

Fuel economy is a major challenge for the automotive industry. A key way to improve lubricant fuel efficiency is by using polymers as viscosity index improvers to maximise the viscosity index of the lubricants. The viscosity index of automotive lubri

Marine Antifouling Coatings Based on Durable Bottlebrush Polymers

Autor: Chiaki Yoshikawa, Ryoma Takagi, Tadashi Nakaji-Hirabayashi, Toshiro Ochi, Yasushi Kawamura, Helmut Thissen

Publikováno v: ACS applied materialsinterfaces. 14(28)

We report a next-generation, biocide-free, and durable marine antifouling coating technology. To achieve this, we combined two different polymers previously developed by us. First, we synthesized well-defined 2-hydroxypropyl acrylamide (HPA) based bo
