选取机引犁壁和畜力犁壁，研究其表面特性与土壤粘附间的内在联系。首次将材料的土壤粘附特性与表面电化学现象联系起来，从理论与试验的结合上证明提高材料的耐蚀性有利于金属材料表面减粘脱土，为触土部件的材料选取、成分优化以及铁基减粘材料的研制提供了简捷有效的参考指标和理论依据 Select the machine lead plow wall and livestock plow wall to study the intrinsic relationship between surface properties and soil adhesion. For the first time, the soil adhesion characteristics of materials are linked with the phenomenon of surface electrochemistry. The combination of theory and test proves that increasing the corrosion resistance of materials is beneficial to the surface de-bonding and de-bonding of metal materials, and the material selection, composition optimization As well as the development of iron-based viscous material provides a simple and effective reference indicators and theoretical basis
