Characteristics of Reducing Adhesion and Resistance of Bionic Coatings Prepared for Touching-soil Components of Terrain Machinery

Characteristics of reducing adhesion and resistance of eleven kinds of bionic coatings prepared for touching-soil components of terrain machinery were investigated in the present work. The influences of bulldozing plate's surface shape, bionic coating's intrinsic contact angle, soil moisture content and bulldozing velocity upon reducing adhesion and resistance of soil were discussed. The sliding resistance between some bionic coatings and soil was measured. The influences produced by bionic coating' s intrinsic contact angle on sliding resistance's adhesion part and the friction angle of coatings to soil were analyzed.
