Which quench the highest hardness , annealing hardness minimum. But different normalizing temperature and different cooling medium is almost difficult to change form a continuous network distribution of the alloy eutectic borides . The experiment also investigated the different processes and carbon impact of heat-treated boron content of the alloy wear resistance , impact abrasive wear test results show that : in the case of 1J impact energy of the carbon content of about 0.40% of the wear-resistant composite panels, the normalized and quenching and tempering the alloy Fe-CB state with increasing boron content, the wear resistance is increased. Boron content of 1.46% of Fe-CB alloys , carbon increases the wear resistance , first increased and then decreased , the highest in the Fe-0.9C-1.46B the normalized wear resistance. The impact of abrasive wear in order to cut furrows, micro cutting , fatigue spalling, brittle flaking based. Source : sdfsdmb
