Because the process is carried out at relatively low temperatures, there is little or no distortion of the mechanical parts during the process. Gas shock absorbers' piston rods from heat-treated steel W.No. 1.1191 were pulse-plasma nitrocarburized at 580$^{\\circ}$C in a gas mixture atmosphere containing 87% N$_{2}$, 11% H$_{2}$ with 2% CO$_{2}$ additions, at a voltage of 375 V and a current of 37 A. The pulse width was 0,480 ms and the pulse pause was 0,020 ms. Distortion of the gas shock absorbers' piston rods increased from 0,00 mm to 0,06 mm on average. The surface roughness Ra increased from 0,125 ?$\\mu$?m, on average, to 0,207 ?$\\mu$?m on average (cca. 60%). The surface hardness of the gas shock absorbers' piston rods with a core hardness of 195 HV1 is 587 HV1, on average. The total depth of the nitrocarburized case (Nht) is 0,52 mm, on average. With use of classic of metallographic techniques the presence of the compound layer, consisting ?$\\epsilon$? - Fe$_{2,3}$(N,C) and ?$\\gama$? - Fe$_{4}$(N,C) phases was observed on the surface. The average thickness of this layer was 23,9 ?$\\um$?m"},{"@xml:lang":"sl","#text":"Nitrocementiranje v pulzirajoči plazmi je termokemični proces, s katerim utrdimo površino strojnih delov, izdelanih iz nizko ogljičnih jekel in jekel za poboljšanje. Nastala nitrocementirana plast z relativno visoko površinsko trdoto povečuje strojnim delom obstojnost proti obrabi in odpornost proti koroziji. Ker proces poteka pri relativno nizki temperaturi, so dimenzijske spremembe pri obdelavi minimalne. Batnice plinskih amortizerjev, izdelane iz jekla za poboljšanje W.No. 1.1191, smo nitrocementirali v pulzirajoči plazmi pri temperaturi 580$^{\\circ}$C v plinski mešanici 87 % N$_{2}$, 11 % H$_{2}$ z dodatkom 2 % CO$_{2}$ pri napetosti 375 V in toku 37 A. Širina pulza je bila 0,480 ms, dolžina pavze pa 0,020 ms. Opletanje batnic plinskih amortizerjev po obdelavi se je v povprečju povečalo od 0,00 mm na 0,06 mm.
