THE ANALYSIS AND IMPROVEMENT OF THE NITRIDING TECHNOLOGY of gas-turbine engine GEAR wheels

A.A. Gukov, L.A. Khasanova

The mathematical model and algorithm for calculating the quality of the nitrided layer from the technological factors and the chemical composition of steel, which enables computer control of the quality of the hardened layer, as well as optimization of technological modes of nitriding are developed. Recommendations for improving the process of nitriding of gears for gas-turbine engine by the use of statistical analysis and modeling are offered.

Key words: nitriding, mathematical modeling, the statistical analysis, gear wheels, parameters of layer quality.
