This paper studies surface properties of metals during chemical–mechanical polishing (CMP). In order to pinpoint the effects of chemistry and mechanical impacts separately, during CMP, we polished Cu and Al surfaces using two distinct slurries of hydrogen peroxide (H 2 O 2 ) and alumina nanoparticles. After polishing, detailed characterization of the surface quality and chemical composition...
Currently, research on the wear map has been gaining more and more attention from tribologists and has led to the creation of a new research area of wear. In this paper, the wear behaviors (wear mechanisms, surface morphology characteristics and wear rates) of Cr ion implanted pure iron lubricated with liquid paraffin in a large range of sliding speed and load were studied. On this basis, a wear map...
An investigation of the tribochemical behavior of Ni ion implanted pure iron was performed. Ni ion implantation increases the wear resistance of pure iron by 30-120% when liquid paraffin is used as lubricant. The wear resistance of ion implanted pure iron increases with increase in surface residual compressive stress, and decreases with increase in microhardness. When liquid paraffin containing zinc...
Ion-beam mixing (IBM) process was used to prepare Ni-Mo multilayer film. Monolayer films of nickel or molybdenum films and Ni-Mo double-layer film were also prepared in a similar manner. Microhardness of the multilayer film was investigated. Tribological properties of the deposited films were systematically measured by a precise measurement apparatus of dynamical friction under unlubricated sliding...
In this paper the phase structure and the distribution of elements in Mo-Ag and Mo-Ni multilayer films deposited by ion-beam mixing (IBM) were investigated using transmission electron microscopy (TEM) and Auger electron spectroscopy (AES). The microhardness and tribological properties of the multilayer films were also investigated. The rubbing surfaces were examined using scanning electron microscopy...
A detailed examination of pure iron unimplanted and implanted with molybdenum ion in two doses by X-ray photoelectron spectroscopy and Auger electron spectroscopy, before and after oil-submerging and wear tests, was conducted to characterize the products between antiwear additive and surface elements of the specimen. The antiwear additive used in this study was sulfurized olefin. The results indicate...
