An analysis of the impact of soil mass pH on the wear process of steel

Abstract

Abstract. The chemical properties of soil mass are among the most important factors affecting the intensity of the wear of working elements. The paper analyses the wear process of 38GSA steel, used in working elements which cut soil, depending on the corrosiveness of the chemical environment. The tests were conducted in natural soil conditions. Changes in the mass of samples depending on soil pH were measured during the tests. Based on the obtained results, it has been concluded that along with an increase in soil acidity, the steel wear intensity also increases. The highest value of wear was observed in acidic soil, followed by neutral, with the lowest value corresponding to alkaline soil.

The Evaluation of the Effectiveness of Reinforcement by Cemented-Carbide Plates in Two Design Variants of the Chisels Intended for Cultivation–Sowing Aggregates

“…This is mainly due to the high variability of the operational forces, which are determined by the physicochemical condition of the soil and the agrotechnical parameters of the elements’ operation. Numerous scientific reports have considered the relationship between the intensity of abrasive wear and the soil moisture [ 8 , 9 , 10 , 11 ], the size and shape of abrasive grains [ 12 , 13 , 14 , 15 ], and soil pH [ 16 , 17 , 18 ]. In addition, the subject of interest of many authors has been the study of the impact of the variability of soil and agrotechnical conditions on the intensity of abrasive wear of various working elements [ 10 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ].…”

Roughness of Ploughshare Working Surface and Mechanisms of Wear during Operation in Various Soils

“…It should be emphasised that elementary processes of abrasive wear, taking place during operation of working elements in soil, are determined also by interactions occurring in the friction contact zone, among others by relative speed of abrasive particles, values of their transmitting forces [42] and also by action of hydrogen, related to acidity of soil [56,57]. The mentioned conditions influence dynamics of the abrasion process and result in a big discrepancy between lifetimes of working elements.…”
