Abstract
The blade in the tillage operation has the most interaction with soil particles. It causes the wear and tear of this piece and reduces its expected life span. Tillage tool wear is of great importance to farmers in terms of economic aspects, reduced quality tillage operations, and increased power consumption. The aim of this study is to investigate wearing of five materials including st37 steel (SST37) plate, galvanized steel (GAS), and fiberglass (GFRP), and two coatings (i.e., titanium nano-nitride (nano-TiN) and tantalum carbide (nano-TaC)) by sputtering in the plasma medium of the layer based on conventional steel. These pieces were tested in three types of light, medium, and heavy soil textures. To assess tool wear, a rotating soilbin was developed. The level of operation of the blades was evaluated in three steps of 500 m and a total of 1500 m with a benchmark of weight loss due to deterioration in the assessment of laboratory operations. There was a significant difference between different treatments. The important point of this research is that the nano-coated blades, owing to their superior properties and the smooth surfaces, showed the least wear. Their abrasion resistance is about 7 times that of the uncoated steel, 5.5 times that of galvanized steel. Fiberglass with reinforced polymer fibers showed a good performance against ordinary and galvanized steel against abrasion.
