Abstract This paper presents the modeling of a cold forging process for rotary sleeve. The EN 42CrMo4 steel part was first modeled numerically by finite element method using simulation software DEFORM 3D ver. 11.0. After that, developed verified experimental tests carried out in laboratory conditions with use 1:2 scale tools and material model aluminum alloy AW-6060. Finite (FEM) results demons...

The influence of plasma nitriding and gas processes on the change surface roughness dimensional accuracy 42CrMo4 steel was investigated in this paper. Both almost always led to changes texture. After nitriding, clusters nitride ions were formed steel, while very often new creation a formation “plate-like” In both cases these processes, compound layer specific thickness formed, although paramete...

The aim of this research was to study the wear behavior of 42CrMo4 steel/ZrO2 composite with 10 and 30 ppi performed ceramic and compare it with the un-reinforced steel under different applied loads. The composite specimens were obtained by pressureless infiltration of the melt into a preformed ceramic of zirconium oxide. The effect of applied load on the specimens wear behavior was ...

This study investigates the effect of different temperatures during deoxidation 42CrMo4 on nonmetallic inclusions (NMI). Tailoring NMIs by a modified temperature is last step before combination reactive and active steel melt filtration. Extensive investigations metallographic sections together with electrolytic extraction allow analysis inclusions’ size distributions, chemical compositions, mor...

The formation of reaction layers between corundum‐based (Al 2 O 3 + C) filter materials covered with functional Al C coatings having different carbon contents and molten steel 42CrMo4 is investigated at the temperature 1600 °C. Within first 60 s, an amorphous layer formed interface original surface steel. This consists mainly Fe small, varying amounts Si. After a longer contact time (120 s), n...
