Change of dynamic parameters of steel after plasma nitriding
Original language description
This experimental investigation is devoted to the analysis of the influence of plasma nitriding on the notch toughness of structural steel DIN 1654/4 (CSN 41 2042.4). The test of the dynamic fracture behaviour of structural steel was carried out using the instrumental Charpy hammer on the plasma nitrided specimens with V and U notch, manufactured according to standard CSN ISO 148-1. The plasma nitriding was implemented at 500 (°C), process duration t = 10 and 20 (h) and variable gas mixture ratio of 24H2: 8N2 (l/h) and 8H2: 24N2 (l/h). The test results showed that nitrided steel became more brittle. However, it was found that for different gas nitriding composition, the notch toughness has behaved quite diversely. The values of notch toughness of steelin case of gas ratio 8H2: 24N2 (l/h) were decreased but for the gas ratio 24H2: 8N2 (l/h), with extension of time, the notch toughness was slightly increased.
