“…Moreover, the repairing costs for a machine are highly variable and good management may keep costs low [19]. Wear in agriculture working parts leads to an increase in fuel consumption and decreasing the lifetime of these parts [20]. The lifetime of agricultural machinery affected by wear and the lifetime of harvester machine is 2000 hours after working time [21].…”

GRICULTURAL production is a world spearhead to face hungry crisis and the main part of this facing is agricultural machinery. Agricultural machinery exposed to failure due to wear and corrosion. This leads to a decreasing lifetime of working parts of agricultural machinery. Agricultural machinery contain seedbed preparation machinery, planting machinery, service and protection machinery, harvesting machinery and post-harvest machinery all types of agricultural machinery deals with different soil condition (soil moistures and soil types), plants (different stem diameter, cutting heights and plants moisture), and agricultural chemical (pesticides and chemical fertilizer). There are many studies searching the optimum method to increase the wear resistance of working parts of agricultural machinery. These methods contain the improvement the new material, hardfacing allying, surface coating, and nanocomposite coating. Nanocomposite coating is a new trend to promote surface properties of the different metal used in manufacturing agricultural machinery. This new trend use nanoparticles as reinforcement in the metal matrix and incorporation process lead to super hardness coating with low corrosion rate and low wear rate compared to conventional surface coating materials.

Ploughbreast is the crucial soil-engaging component of horizontally reversible plough (HRP). Its biggest merit, compared to conventional ploughs, is to enable the ploughbody to perform alternative and shifting tillage operations with high speeds. A major technical challenge in the aforementioned operation is violent flowing interaction between soil and ploughbreast. This flowing interaction may result in severe wear rate on the ploughbreast, particularly along its cutting edge, i.e. ploughshank, thereby reducing the tool life. The objective of the present paper is to evaluate influences of the flowing interaction on the ploughshank by studying interaction force, wear rate and their correlation. The interaction forces were predicted using a numerical calculation with finite volume approach in computational fluid dynamics (CFD) software. The wear rates were measured using scanning electron microscope (SEM). There were very good qualitative agreements between numerical and experimental results that either the maximum force or the most severe wear rate appears at the same section and has a direct relationship with the Tillage speed and tilling depth. Closer examination of the calculated and measured confirms that the more violent sliding & rubbing, the greater stress gradient and the larger abrupt stress cause the more severe wear rate along the ploughshank.

The abrasion failure is the key factor for prolonging the service life and energy saving of furrow openers. The hardness enhancement was reported to be an effective strategy to increase the wear resistance against the soil abrasion. D517 coatings were deposited on Q235 steel by electric spark to improve the wear-resistant property with an affordable cost for farmers. The wear behavior of the coatings was characterized in a pin on disk friction equipment and a homemade soil abrasion simulation system. The soil adhesion, which is highly related to energy consumption, was also evaluated. Results showed that D517 coatings revealed dendrite structure with some randomly distributed carbides. The electric current exerted a great influence on the microstructure, hardness, friction coefficient, and soil wear rate. The wear rate of samples deposited with 80 A and 90 A reduced to 79% and 84%, respectively, as compared with the normalized heat-treated 65 Mn steel after 6 h in soil. This work provides a promising solution to increase the wear resistance of furrow openers. It needs to be noted that the coating would increase the soil adhesion of the opener, which needs to be further explored to decrease the energy consumption.
