For surface tillage operation there widely used disc harrows, working bodies of which are discs wearing out during operation. The wear intensity of discs depends on the wear resistance of their working surfaces, working modes and properties of the culti- vated soil. It has been found that an effective way to increase the life of discs is surfacing them with wear-resistant materials. The aim of the work is to study the wear out of surfac- ing materials, which can be used to harden discs and to make recommendation for the use of these materials in the repair departments of agricultural enterprises. Materials and Methods. Surfacing with electrodes T-590 and powder wires PP-Np200Kh15S1GRT, VELTEK-N560.02 and PP-Np280Kh9F7SG4 were taken as test materials. For wear tests of materials in abrasive mass, there was used an apparatus to simulate the moisture content and composition (sandy loam or loam) of the soil. In the disk-pad tests, the effect of abrasive particle size, load and sliding friction velocity on the wear of the materials was studied. In field tests, wear of the disks made of 65G steel, surfaced toothed and solid disks were monitored. Results. Laboratory studies of the materials revealed the effect of TI - The Use of Surfacing Materials to Increase the Durability of Disc Harrow Working Elements JF - Engineering Technologies and Systems DO - 10.15507/2658-4123.031.202104.544-558 DA - 2021-12-30 UR - https://www.deepdyve.com/lp/unpaywall/the-use-of-surfacing-materials-to-increase-the-durability-of-disc-1gbXOLWbE6 DP - DeepDyve ER -
