Microtructure and Performances of Aluminium Based Ni-P/Nano-diamond Laminated Cladding
With the premise of reasonable choosing Ni-P alloy and processing conditions,the effects of mixing speed and nano-diamond concentration on the microstructure of cladding layer were studied,and the wear resistances were tested.The results show that,with the same nano-diamond concentration in the plating bath,the mixing speed 300 r/min,the surface topography is best.When the addition of nano-diamond is 6 g/L,the surface topography microstructure is well-distributed as well as fine and close,and the friction coefficient is low and stable.
