Experimental investigation of the influence of modes of nitriding on the damping ability of 45 steel

By using numerical methods, for specimens of 45 steel subjected to various modes of nitriding in a hydrogen-free atmosphere, we determine the parameters of the process of nitriding guaranteeing the maximum possible level of their damping ability. The results of testing control specimens of 45 steel subjected to the optimal procedure of nitriding revealed practically complete coincidence between the numerical and experimental values of the decrement of vibrations whose level was higher than for nonnitrided specimens by a factor of 3.4.
