Influence of Sintering Temperature on Hardness of Diamond Reinforced Cu-Fe Based Composite
The diamond reinforced Cu-Fe based composite was prepared by vacuum impressed sintering.Consequently,the influences of sintering temperature on the hardness of the composite were investigated by microscope,XRD and hardness test.The results show that the bonding way between elements is metallurgical bonding and the alloying rate rises with the increase of sintering temperature.When the sintering temperature is 930 ℃,the diamond and Cu-Fe matrix has fine combination,the highest hardness reaches 166.7 HB.
