Search for: [Abstrakt = "The paper presents results of surface condition examinations of martensitic X39Cr13 steel subject to heat and surface treatment \(plasma nitriding\). The heat treatment consisted of compressed nitrogen quenching from 1050 °C \(1323 K\) and two\-hours tempering at 300 °C \(573 K\) and 620 °C \(893 K\) for specimens subject to nitriding. The plasma nitriding was carried out in an ion\-nitriding installation with cooled anode, at temperature of 460 °C \(733 K\), at pressure of 150 Pa and during t = 20 h \(72 ks\)\; 25%N2\+75%H2 was used as the reactive atmosphere. Specimens surface was examined using a profilographometer designed for surface 2D and 3D examinations using a contact method. Surface topography measurements were carried out on specimens taken from 1 mm thick sheet. 1.5 mm×1.5 mm surface was the measurement area. The sampling interval in X and Y axis was 1 μm, while the measuring speed was 0.5 mm\/s. The studies carried out allowed evaluating the conditions of examined steel surface through the comparison of stereometric parameters of the surface."]
