Helped the laser. In the Russian Federation came up with how to make steel stronger


Surface reinforcement of steel allows to increase the strength of parts working in conditions of wear of machines and tools. The technology can be improved by using nanocarbon materials such as fullerene, graphene or nanocarbon tubes, and a laser for surface treatment, the newspaper writes with reference to the Krasnoyarsk Scientific Center of the SB RAS.

“Scientists have chosen carbon black as nanomaterial, which is obtained by the production of fullerenes in an arc discharge with graphite electrodes. After laser treatment, the hardness of iron coated with nanostructured carbon increased by more than five times compared with the most common industrial steel. The coefficient of friction of the reinforced material was 20 – 30% lower than that of the original samples, ”the report says.

The hardness and wear resistance of steels, especially those containing carbon, nitrogen or boron compounds, are significantly improved after laser treatment. In addition, laser heating does not cause deformation of the products, which reduces the technological process, since there is no need for additional processing of metal products,
told researcher Alexander Eletsky.

Employees of the Krasnoyarsk Scientific Center of the Siberian Branch of the Russian Academy of Sciences, NRU MEI and the Moscow Automobile and Road State Technical University (MADI) took part in the study.

      It's like that. This generation would write jokes, not news.
      Surface hardening, alloying, hardening, surfacing, other types of surface modification ...
      A special laser for this with an even distribution of power in the spot.
      These works were carried out in the 70-80s. See the list of references in the doctoral dissertation of one of those specialists. http://tekhnosfera.com/tiporyad-mnogokanalnyh-vol

        It is not hardness that increases, but microhardness, which is determined by the Vickers scale.

      This is not related to heat treatment. It used to be called hardening, that is, applying a surface layer to an already finished part. I worked in the tool industry, we have strengthened the working edges of the die matrix, for example, to increase the service life between current repairs. Increased tool life. Made using electric erosion machines, a short-term electric arc, in fact. After this treatment, the surface had a low roughness class, so it was doubtful on the rubbing parts. With the help of a laser, this defect may have been eliminated.
      In general, the Kaliningrad “Quartz” made installations for hardening, after which the details were smooth and clean. So technologies were a quarter century ago different. smile

        We once provided such a service - laser processing of cylinder mirrors. It seems that this operation is used now for boosting engines. As I understand it, the micropiks of the metal remaining after grinding are melted and aligned to a large extent. Since the laser heats the surface very locally, with the right settings, there was no significant change in the surface structure, just everything was smoothed out.

          Bearing inserts, articulations of crankshafts, cylinders, friction parts of rotors, gearboxes. I would like this spraying in gearboxes of power tools, this would negate the problem of price / quality. On metalworking machines would have come in handy too. True, such a layer is hardly refractory and will collapse under high friction

          The bottom line is that hardening of the armor plate does not occur, but only a micron layer is created on the surface, as I understand it, it is considered innovative only by the fact that this layer is compacted with nanotechnology and the hardness (not strength) of the layer is compacted by carbon tubes with relatives (the same carbon) ... that’s the whole innovation ... For surface wear and sliding properties it’s ideal, I think in engine building the very thing, there is hope for an increase in the resource of engines in the future.

            In other words, hardening does not occur over the entire thickness of the steel sheet ... hmm ... then really, most likely it will be more useful in the automotive industry.

              That's right, the automotive industry is not a panacea, all engines, including turbines, will gain a lot, wear + minimal friction ... this is necessary in many areas ...

                and if you apply a multi-layer grid to the cell system to calibrate the gratings (which is unlikely), then we get the band effect and this is already polar protection lol erosion 0,001%
