purchased from Sinopharm Chemical Reagent Co., Ltd., and used as received. 2.2 Preparation of uniform PmPD micro-particles Uniform PmPD micro-particles were synthesized at 25 °C using ammonium persulfate..., PmPD micro-particles were separated from the solution and washed with distilled water twice for further characterization. The concentration of filtrate was determined by barium chromate......

as wear particles. Abrasive wear and adhesive wear co-exist in the worn scar. However, in Fig.6(b), the amorphous phase in the coatings is disadvantageous to peeling wear. The wear track of the coating reveals pits and grooves. In the course of test, the pits result from the disengaging of the micro-particles from the surface. Compared with the substrate, the adhesive wear is feeble in the coating......

ionization and the flow resistance of charged micro-particles. For the present Ni-alloy, on the one hand, with the addition of Cr, Mo and Cu, the binding energy E (about 37% for γ-(Ni-Cr-Mo) units... be endowed with more excellent properties, which constructs a wide range of nickel-base corrosion resistant alloys. However, up to now, the nature and micro-mechanism of its corrosion resistant behavior......
contained in the electrolytes easily transform into colloidal micro-particles with negative charge and are incorporated in the coating. These processes change the microstructure of the coating, which may... and this usually corresponds to oxide recrystallization and defect appearance in the film structure. Region(4) begins with intensive oxygen evolution, which creates a background for the onset of plasma micro......
of reagents are used in RCA cleaning process such as NH4OH, HCl, H2O2 and HF that will pollute the environment and when the feature size is smaller than 0.13 μm, the removal of micro-particles... the Van der Waals forces and static forces. In order to suppress particles depositing on the wafer surface, it is essential that the wafer surface and the particles should have the same polarity......

into the melt by inert gas and stirring was used to prepare aluminum matrix composites (AMCs) reinforced with Al2O3 particles. Different mass fractions of micro alumina particles were injected into the melt... and weak mechanical properties. In the present work, pure aluminum (Al 1000) was reinforced with micro sized Al2O3 particles in different mass fractions of 3%, 5% and 7%, respectively. The composites......
