Short Penning-A Technique to Resist Wear of Critical Components of Agricultural Machinery

Several machines are used to perform soil manipulation and other farm operations. The critical components of these machines especially soil engaging tools, cutter bar blades of harvesters and pegs of threshers etc are subjected to abrasive, corrosive and adhesive wear and some secondary wear like surface fatigue, fretting and cavitations erosion. The wear intensity of machine parts depends upon the physio-mechanical properties of the environment in which the machines are operating (adhesion, compaction, resistance to shear, coefficient of friction etc.); intensity of load and contact pressure; and the materials of construction and heat treatment of the material. Bulk and surface treatment and use of appropriate material are used to enhance wear resistance of these critical components. This paper provides in-depth of shot peening techniques to resist abrasive wear of these components.
