Abstract Generally, soil seriously resists the motionn of soil-engaging components of terrain machines and tillage equipment because soil has such strong adhesion. In order to develop a method to treat this problem, a polysiloxane/T8 composite coating was used in this study. The wettability of steel 45, steel T8, polysiloxane coating, and polysiloxane/T8 composite coating was measured using a contact angle testing instrument (JCC-1, made in China) at 20°C in air. The abrasive wear resistance of both steel 45 and polysiloxane/T8 composite coating was tested on a turnplate abrasive wear testing machine. The resistance of soil to bulldozing plates made of the aforementioned materials was measured on bulldozing resistance testing equipment. The experimental results showed that the polysiloxane/T8 composite coating had excellent hydrophobicity, and that the contact angle of water on its surface reached up to 92°, which is much larger than that of steel 45 and steel T8. The relative volume wear loss of the polysiloxane/T8 composite coating was 65% and its bulldozing resistance was reduced by 15.2%–22.3% compared to bare steel 45. Ausführliche Beschreibung
