Jan 01,2012 42crmo4 nitriding hardness#0183;Ion nitriding treatment of 42CrMo4 steel improves their fatigue strength by 32% as compared with the untreated state.This improvement is the result of the beneficial effects of the superficial work- hardening and of the stabilized compressive residual stress.The notch region is found to be the fatigue crack nucleation site resulting from a stress concentration (Kt = 1.6).The localEffects of Surface Morphology on the Wear andresistance,surface hardness,and fatigue strength.Modication of the steel surface by gaseous nitrocar-burizing and nitriding is a process that is widely used in manufacturing of machine components and tools,since an improved surface hardness,fatigue strength,and wear and corrosion resistance can thus be achieved at minimum distortion.Crack initiation in the very high cycle fatigue regime of Two different plasma-nitriding treatments were performed on a quenched and tempered 42CrMo4 cast steel.Ultrasonic fatigue tests were performed up to 10 9 cycles.Resonant frequency and the nonlinearity parameter were recorded in situ during the fatigue tests.
Since the nitriding temperature was only 10 K higher than the tempering temperature,nitriding decreased the core hardness.This loss was a time-dependent process and,consequently,more pronounced for batch 1,which had a higher nitriding time.Furthermore,the longer nitriding time led to a decrease in surface hardness and to an increase in NHD.Corrosion behaviour of the 42CrMo4 Steel Nitrided by The results for nitrided samples can be interpreted in terms of two time constants overlapped for a broad frequency range.The electrochemical behaviour for 42CrMo4 untreated was modelled by the equivalent circuit shown in figure 3 which is composed by circuit elements R e,representing the solution ohmic resistance between the working and the reference electrodes,Q element,which represents Coatings Free Full-Text The Effect of Temperature A gas-nitrided layer was produced on the toughened 42CrMo4 low-alloy steel using the changeable nitriding potential in order to limit the thickness of a brittle zone.The microstructure consisted of the compound + ( + ) zone and diffusion zone (nitric sorbite with precipitates).Such a layer was subjected to laser heat treatment with or without remelting.
