| Abstract: | The situ precipitation particle reinforced metal matrix composite clad layer was fabricated on ductile iron surface by laser cladding using replaced FeC-SiB alloy powders.The optimal SRV tests were carried out by using laser clad layers as upper samples and grey cast iron as low samples.The tests show that the clad layer is dense,metallurgical bond is fine.The wear depth is 0.84μm,1.79μm and friction coefficient is 0.065-0.078 when it is composed of friction with gray cast iron.The friction coefficient is decreased with the increase of wear time,that show they have good wear resistance and pair combination. |
