Restoration of Agricultural Machines Surfaces by White Cast Iron with the Formation of Technological Repair Units

Abstract

This article develops a fundamentally new approach in the selection of optimal methods for restoring of worn surfaces of agricultural machines’ tools with the formation and application of technological repair units. Based on the systematization and linkage of modular worn-out surfaces, their operating conditions, technological environment and the choice of their optimal combinations, it found a low-cost method of restoring details with white cast iron to gain a necessary quality of a new surface layer.

“…In addition, the synthesis of TRU revealed the most optimal method of obtaining wear-resistant coatings to prolong the durability of the functional surface of the working tools by electro-sparking surfacing with unalloyed white iron [6,7]. After studying various methods of applying wear-resistant coatings [1-5, 9-12], a method of electro-sparking welding was developed that includes contact treatment by a rotating electrode, which differs from existing methods in the following point: during the coating process, the defective layer is continuously removed from the working surface of the rotating electrode.…”
