This is because the surface of aluminium powder particles is enriched with a large number of electrons, and graphene is adsorbed to the surface[6].
With the increase of milling time, the number of friction between particles increases, and graphene adsorbed to the surface gradually disperses on the flattened aluminium powder particles.

Only consider the ideal circumstances of the leakage between block bodies and floating block slot, the theoretical average flow of pump formula is possible to write: (1) where ——vane lift ——floating block depth ——rotational speed ——number of vanes 1——floating block thickness 2——vane thickness ——vane obliquity R1——minimum cam radius R2——maximum cam radius ——gap depth on uprightness in velocity of flow ——gap height p1——high pressure of gap p2——low pressure of gap ——gap length ——dynamical mucosity degree of oil The simulation of power in the pump system Based on the above analysis and the principles of pump to establish the output power equation.
Parameters selection In the light of all kinds of parameters on the VOP vane pump which was made in Dalian hydraulic component factory, the new pump parameters as follows: (1) the rotational speed from 500 to 3200 r/min, the work pressure: 6MPa; (2) maximum cam radius: 22.6mm, minimum cam radius: 19.3mm, rotor radius: 19mm, number of vanes: 10, floating block thickness: 20mm, vane thickness: 1.4mm;(3) the overall high of floating body designs about4.76 mm, the width of the top floating pieces is 5.0 mm, the high of the arc is about 0.16 mm, and then linked to the rectangle structure is about 5.0 mm width and 0.30 mm high.

Two times are important in the KMC simulation, one is the average time interval between the arrival of two atoms in a 2D lattice model (∆t), and the other is the net residence time tn [10], which are given by Eq. 2 and Eq. 3: Dt = 3re 2nR (2) N tn =1/ å Pi i=1 (3) where R is the deposition rate, n is the number of atoms comprising a monolayer in a close-packed simulation system, and N is the number of different types of jump.
As can be seen from Fig. 1, there exist few vacancy in Ni-Cr alloy film and grain size is large for incident angle of 0˚, 15˚ and 30˚, and the smooth surface slightly roughs with incident angle increasing, show as Fig. 1 (a), (b) and (c).
