Project abstract

The project idea is based on developing a technological process for plasma nitriding of steel injectors for liquid fertilizer application. Within this project, a plasma nitriding mode that improves the tribological and corrosion characteristics of austenitic stainless steel 12X18H10T has been developed. Additionally, comprehensive studies of the effect of plasma nitriding temperature (400÷700°C) on the phase composition, structure, microhardness, corrosion resistance, and durability of austenitic stainless steel 12X18H10T need to be conducted. A test stand will be developed for testing hardened steel injectors under conditions that simulate the actual operation of a liquid fertilizer application unit. As a result of the project implementation, systematic experimental data on the behavior of the nitrided layer of steel 12X18H10T under combined exposure and wear will be obtained. Full tests of durable injectors for liquid fertilizer application will be conducted. Based on laboratory, bench, and field tests, a technological plan for continued operation will be developed.

The scientific novelty of the project is as follows:

  • For the first time, ion-plasma nitriding has been implemented to extend the service life of steel injectors for liquid fertilizer application;
  • For the first time, the wear resistance of nitrided stainless steel 12X18H10T has been studied under the synergistic effect of an aggressive environment (corrosion-active salts) and abrasive particles (soil);
  • New data on the tribological characteristics of the nitrided layer of stainless steel 12X18H10T obtained by plasma nitriding in an N2-H2 environment will be obtained from the official representative of the United Kingdom.

The goal of the project: To develop a technological process for plasma nitriding that allows for the strengthening of steel injectors intended for liquid fertilizer application, and to study changes in structural-phase processes, mechanical, tribological, and corrosion characteristics depending on the plasma nitriding modes.

Expected and achieved results of the project:

The results obtained from the research.
Publications (with links to them) and patents; information for potential users

2024

The plasma nitriding installation will be upgraded to increase its productivity. During the upgrade, the design of the sample/product holder will be changed, and the power source capacity will be increased.

The influence of plasma nitriding modes (temperature and duration of saturation) on the microstructure, hardness, and adhesion strength of the nitrided layer of 12X18H10T steel will be investigated. Optimal plasma nitriding parameters will be established to ensure high hardness and uniformly distributed structure.

The features of the formation of the nitrided layer depending on the hydrogen content in the gas mixture will be studied. The optimal hydrogen concentration will be determined to ensure increased hardness and thickness of the nitrided layer, as well as reduced oxide formation on the surface of the samples.

2025

The influence of structural defects formed after intensive plastic deformation of the surface on nitrogen diffusion and the formation of the modified layer during nitriding will be established. The phase composition of the samples will be studied by X-ray structural analysis using an X-ray diffractometer (XRD) DW-27.

The corrosion and tribological characteristics of 12X18H10T steel will be investigated depending on temperature. Systematized studies of the effect of ion-plasma nitriding temperature (400÷700°C) in arc discharges will be conducted. Values of corrosion potential, current density, and corrosion rate will be measured.

Tests of nitrided samples of 12X18H10T steel for resistance to abrasive wear according to GOST 23.208-79 will be carried out. The wear of the sample is assessed by the change in the weight of the tested sample.

2026

The relationship between the structure of the nitrided layer and its tribological characteristics will be studied. The patterns characterizing the initial structure of the surface layer and the relationship between the structure obtained in the deformation zone during friction and the tribotechnical characteristics will be established.

Bench tests for wear resistance and corrosion resistance of nitrided parts made of 12X18H10T steel will be conducted. Bench tests of treated and untreated parts (soil-working tools) to assess their service life will be carried out on a special bench - a soil bunker that simulates real field conditions.

Field tests of injectors made of nitrided steel for liquid fertilizer application will be conducted.

Based on laboratory, bench, and field tests, a technological plan for the further implementation of the technology developed for strengthening injectors for liquid fertilizer application in the root zone will be developed.

At least 3 (three) articles and/or reviews will be published in peer-reviewed scientific journals indexed in the Science Citation Index Expanded database of the Web of Science and/or with a percentile in the CiteScore database of Scopus of at least 50 (fifty), as well as at least 1 patent for an invention (including a positive decision on it) based on the results obtained within the framework of this project.
