With modified grey iron as substrate,assembled with graphite as lubrication material,the grey iron/graphite composite antifriction plate was designed and developed according to the requirement of steam generator in a nuclear power plant,and the microstructure analyzation,mechanical test and friction test were carried out.The results show that the compressive yield strength of the modified grey iron was 790 MPa;the ultimate bearing capacity of the antifriction plate was 49 770 kN,providing the efficient support for the steam generator of nuclear power.When rubbing under the load less than 6 500 kN for 1 000 times,the friction coefficient of the antifriction plate was stable and below 0.15;the wear value was also less than 0.13 mm,indicating excellent bearing capability and antifriction performance.The values of friction coefficient and wear loss both reached the technical requirement.
