Abstract
To improve the wearresistance of farm tools,the surface composites with WC particleshighchrome cast iron were achieved on cast iron by castinplace surface alloying,and the abrasive behavior of the composites was studied using a MM200 wear tester. The experiment results showed that the main effect on the quality of the composites is casting temperature, and then abrasive wearresistance of the composites was increased from 1.8 to 5.3 times compared with 65Mn steel quenched. The field test results also indicated that the technology, making the surface composite with WC particleshighchrome cast iron,can raise the service life of farm tool considerably.
