| Abstract: | The fatigue strength and wear resistance of steels St. 3, P-1, EI-802, and EI-612 after vacuum-diffusion chromizing, siliciding and boriding was studied. It was shown that the wear resistance of carbon steels is increased more than 20-fold by boriding, being approximately doubled by chromizing, and increased 1.3 times by siliciding. Of the alloy steels, only steel EI-612 has its wear resistance increased by vacuum chromizing. The fatigue strength was reduced in every case by 20–50%. |
