Abstract
Agricultural 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.
