NANOCOMPOSITE nc-TiC/a-C:H FILMS FABRICATED BY DUAL PLASMA TECHNIQUE
WANG, YAOHUI; ZHANG, XU; XU, YUANZHI; WU, XIANYING; … - In: Surface Review and Letters (SRL) 14 (2007) 05, pp. 891-897
Nanocomposite nc-TiC/a-C:H films have been deposited via filtered cathodic vacuum arc technique, employing Ti target and C2H2 gas as material precursors. The composition and nanostructure of film, correlated to mechanical and tribological properties of film, are varied by changing C2H2 flow rate...

RESEARCH OF MECHANICAL PROPERTY GRADIENT DISTRIBUTION OF Al-Cu ALLOY IN CENTRIFUGAL CASTING
SUN, ZHI; SUI, YANWEI; LIU, AIHUI; LI, BANGSHENG; GUO, … - In: Surface Review and Letters (SRL) 18 (2011) 06, pp. 297-301
Al-Cu alloy castings are obtained using centrifugal casting. The regularity of mechanical property gradient distribution of Al-Cu alloy castings with the same centrifugal radius at different positions is investigated. The result shows that the tensile strength, yield strength, elongation and...

ADHERENT NANO-SUPERHARD TITANIUM NITRIDE FILM AND ITS FORMING MECHANISM IN MULTI-ARC ION-PLATING SYSTEM
YU, XIANG; WANG, CHENGBIAO; HUA, MENG; TAM, PUILAM; … - In: Surface Review and Letters (SRL) 14 (2007) 04, pp. 789-793
An adherent nano-superhard titanium nitride (TiN) film on the substrate of Cr12Mo4V high speed steel was prefabricated in a vacuum cathode multi-arc ion-plating system. Microhardness, film-to-substrate adhesion, and microstructure of the film were investigated typically using Vickers hardometer,...

STUDY ON THE PEIREL–NABARRO STRESS OF IRON ALUMINIDES
PANG, L. X.; HAN, N. F.; SHI, H.; XU, J.; HAO, X. H.; … - In: Surface Review and Letters (SRL) 19 (2012) 06, pp. 1250057-1
The modified Peirel–Nabarro model of dislocations is not valid for the superdislocation bounded by the antiphase domain boundaries in long-range ordered intermetallic. In this work, a new Peirel–Nabarro Stress model is developed to take into account the critical resolved shear stress of...
