Iron Casting with Mo-Alloyed and W-Alloyed for Wear Resistance and Laser Surface Modification-Laser Surface Modification of Cast Iron Aimed at Refining the Wear Resistance (Report 3)
Autor: Tsuyoshi Utsunomiya, Toru Nagai, Masao Uemura, Hideki Hattori, Junzo Fujioka
Publikováno v: QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY. 22:132-140
Cast iron has been widely used for the parts of sliding wear such as cylinder bores of motor engines because of its high resistance, which is mainly due to the fine pearlite structure and the existence of graphite acting as a solid lubricant. These f

Autor: Sadao Fujii, Takeshi Hasegawa, Junzo Fujioka, Masahito Ban
Publikováno v: Diamond and Related Materials. 12:47-56
Diamond-like carbon (DLC) films prepared using CH 4 or C 6 H 6 with varying deposition parameters by an electron beam excited plasma CVD system were investigated for the internal stress, dynamic hardness and structural properties such as the film den

Wear Resistance of the Surface-Modified Cast Iron by Laser Melting-Laser Surface Modification of Cast Iron Aimed at Refining the Wear Resistance (Report 2)
Autor: Tsuyoshi Utsunomiya, Junzo Fujioka, Toru Nagai, Masao Uemura, Hideki Hattori
Publikováno v: QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY. 21:474-480
The authors have studied on the laser surface modification of cast iron aimed at refining the wear resistance. It was already reported that cooling rate in solidification is varied by laser condition and that a fine martensite-ledeburite microstructu

Tribological characteristics of Si-containing diamond-like carbon films under oil-lubrication
Autor: Sadao Fujii, Masahito Ban, Junzo Fujioka, Makoto Ryoji
Publikováno v: Wear. 253:331-338
Tribological behaviors of Si-containing diamond-like carbon (DLC) and DLC films deposited by an electron beam excited plasma (EBEP)–CVD system were investigated for applications to mechanical components. The ball-on-disc tests against bearing steel

Diamond-like carbon films deposited by electron beam excited plasma chemical vapor deposition
Autor: Sadao Fujii, Masahito Ban, Takeshi Hasegawa, Junzo Fujioka, Yukitaka Mori, Makoto Ryoji
Publikováno v: Diamond and Related Materials. 11:1353-1359
An electron beam excited plasma (EBEP) system can produce a high-density plasma by introducing a high-current and low-energy electron beam into a process chamber. Diamond-like carbon (DLC) films prepared by EBEP-CVD systems were investigated for depo

Autor: Yasuo Shimizu, Kazuhiko Sakaki, Takahiro Yoshikane, Junzo Fujioka, Motoharu Komatz
Publikováno v: Thermal Spray 2004: Proceedings from the International Thermal Spray Conference.
HVOF sprayed Cr3C2-NiCr cermet coating was investigated to improve the erosion resisting performance of the coal burning boiler tube exposed by fly ash erosion. SUS 310S stainless steel substrate was used to examine the effect of surface treatments.
