Analysis of Multiple Indicators of Ion Nitrided Layers of BH11 Steel

Abstract:

In modern scientific and engineering expertise there are a few methods for graphical computational analysis related to decision making. However, few of them are devoted to materials science and the determination of the complex of properties separately and simultaneously. This research proposes a decision analysis approach tested for the basic properties of BH11 steel. With the help of the approach the tendencies as technological regimes in the change of the microhardness Hv, the relative wear resistance Kv and the connected nitride zone δnz are established. A model for the phase composition is derived, which interprets all observed trends and technological regimes for the relatively minimal and relatively maximal studied values. Thus, the efficiency of the technology in processing the considered steel is associated with the structure and properties of ion nitrided layers, which as a research is the main task of materials science.
