Straw reaper is an agricultural machine that performs the pooled tasks of cutting, threshing, and cleaning straw in a single operation. It is well-appreciated machinery in the farming sector because it clears fields faster for the next crop cycle by covering a larger area in a shorter period of time. Cutting straw in abrasive environments and at high temperatures causes significant surface damage to the cutting blade. This surface damage increases the machine's cutting costs and shortens the blade's life. To overcome this problem, the surface improvement of the straw reaper blade emerged as a substantial solution. The current study applied a cryogenic treatment to the blade material and evaluated it using a pin-on-disk wear test setup with Taguchi's L18 orthogonal array. The workpiece type, time, load, and sliding velocity were selected as process parameters and wear loss was observed as output response. The results revealed that cryogenic treatment improved the blade's wear resistance by 14.28% compared to an untreated surface, and ANOVA showed that workpiece type, load, and sliding velocity have a significant role in controlling the blade's wear behavior. The optimized parametric setting for the lesser wear was found as A2 (Treated workpiece); B1 (Load 15 N); C1 (Sliding Velocity 1.31 m/s); D3 (Time 15 min). The FE-SEM analysis revealed that the cryogenic treatment refined the grain structure, which improved the wear resistance of the material.

摘要

Straw reaper is an agricultural machine that performs the pooled tasks of cutting, threshing, and cleaning straw in a single operation. It is well-appreciated machinery in the farming sector because it clears fields faster for the next crop cycle by covering a larger area in a shorter period of time. Cutting straw in abrasive environments and at high temperatures causes significant surface damage to the cutting blade. This surface damage increases the machine's cutting costs and shortens the blade's life. To overcome this problem, the surface improvement of the straw reaper blade emerged as a substantial solution. The current study applied a cryogenic treatment to the blade material and evaluated it using a pin-on-disk wear test setup with Taguchi's L18 orthogonal array. The workpiece type, time, load, and sliding velocity were selected as process parameters and wear loss was observed as output response. The results revealed that cryogenic treatment improved the blade's wear resistance by 14.28% compared to an untreated surface, and ANOVA showed that workpiece type, load, and sliding velocity have a significant role in controlling the blade's wear behavior. The optimized parametric setting for the lesser wear was found as A2 (Treated workpiece); B1 (Load 15 N); C1 (Sliding Velocity 1.31 m/s); D3 (Time 15 min). The FE-SEM analysis revealed that the cryogenic treatment refined the grain structure, which improved the wear resistance of the material.
