AN ASSESSMENT METHOD OF HEAT TREATMENT PARAMETERS AND SELECTED SYNERGIES FOR THE DEVELOPMENT OF STEEL FOR NITRIDING

Journal Title: Tribologia - Year 2013, Vol 250, Issue 4

Abstract

Nitriding is one of the ways to improve the construction characteristics of different types of steel. Nitriding is a heat input for the diffuse nitrogen saturation of the surface layer of the steel element. This process consists of the introduction to a film passing through the steel object, which is associated with iron overload and especially aluminium, creating a surface layer of borides. In contrast to surface area nitriding cured without additional heat treatment, nitriding is constantly tempered. This work uses statistical methods to design experiments. The plan is to complete a fractional factorial design 2 (3-0) to identify the impact of three parameters of the heat treatment on the evolution of the mechanical properties of steel. On the basis of the results of planned and carried out experiments involving the nitriding of steel in accordance with the scheduled set of parameter values of the heat treatment, Regression models were developed that capture the impact of the parameter values of the heat treatment on the mechanical properties of selected steel grades.

THE INFLUENCE OF THE CHEMICAL STRUCTURE OF LIQUID-CRYSTALLINE COMPOUNDS ADDED TO PARAFFIN OIL ON TRIBOLOGICAL PROPERTIES OF LUBRICANT MIXTURES

Liquid-crystalline compounds added to typical lubricants, such as mineral oils, improve their tribological properties [L. 13]. The aim of this work was to study the influence of the chemical structure of liquid-crystall...
