LOU Bai-yang(楼白杨), CHEN Zhen(陈 阵), BAI Wan-jin(白万金), DONG Gang(董 刚)
MOE Key Laboratory of ..., Cr, Fe, C and Si. It is obvious from the erosion test that the Ni60A/SiC coating has high erosion resistance.
Key words: laser cladding; Ni60A; SiC; erosion resistance
particles saltation process. Sand saltation motion usually plays the key role in the wind-erosion process [10]. Sand saltation movement generates approximately 75% of the sand transport flux [11, 12... is given as k(G, U, D). Sand particle is assumed as a sphere and only effected by gravity and air resistance during the movement in the air. Then the status of sand particles in any moment during......Numerical simulation of sand load applied on high-speed train in sand environment

for the anti-erosion of C/C composites [18-21]. And the interface composition is important to the erosion resistance of SiCf/SiC composites [22]. To make C/C-SiC composites more competent for application, there has been strong interest in optimizing their ingredients and microstructures to develop the erosion resistance [23]. Ductile Al modified C/C-SiC composites have lower preparation temperature [24......
