Results of Laboratory Wear Testing of Materials of G-Shaped Freeze-Cultivator Knives

This article presents a comprehensive analysis of the wear behavior of G-shaped blades used in milling cultivators under controlled laboratory conditions. The study specifically focuses on evaluating how various operational factors influence the wear intensity of the blade material. Among the key parameters analyzed are the applied pressure force, the total duration of the testing process, the linear friction speed between the blade surface and the abrasive medium, as well as the rate of abrasive material consumption throughout the test cycle. The laboratory experiments were designed to simulate realistic working conditions to which the blades are typically subjected during soil cultivation operations. By systematically varying the pressure force applied to the blade samples, the researchers were able to observe and quantify the correlation between increasing load and material wear rate. Higher pressure levels generally led to a more intense abrasion effect, highlighting the critical importance of optimizing operational loads during field use. Another significant factor investigated was the testing duration. It was observed that prolonged exposure of the blade materials to abrasive interaction progressively increased the wear depth, which directly correlates with reduced blade service life. This finding underscores the necessity of selecting materials with enhanced wear resistance for longer operational cycles.
