Tillage component wear is a serious concern in agricultural regions. There is a contradiction between the improved hardness of tillage component and weakened mechanical strength. In order to solve this problem, the paper introduced a structure and material coupling bionics surface texture that was acquired by structuring the bionics surface texture and controlling the processing of the cast. The test results showed that the single bionics surface texture or setting small chill did not produce the white iron structure, and via combining the two methods, the white iron structure was appeared. The analysis results indicated that bionics surface texture can limit the melting flow and setting small chill can enhance the part undercooling degree, realizing the design method of the coupling bionics surface texture. The micro hardness test results showed that coupling bionics surface texture has higher micro hardness and the average value was improved by 35.71% compared with the core matrix. The scratch test results showed that when forming the same width of scratches, it needed 1.16 times load for the core matrix. The wettability test results showed that the average contact angle of the coupling bionics surface texture was high, and the values were increased by 14.91% compared with the core matrix. The coupling bionics surface texture can be used to design the tillage component that possesses high wear resistance, high mechanical strength and low soil adhesion.
