Pereverzev, V. Kolmykov, V. Vorotnikov] Conclusions: 1. The relationship of abrasive wear resistance ε of steels to carbide phase content in the 0 to 90% range in carburized cases is not a steady one. With a carbon content above the critical, ε increases very rapidly, which may be explained by the change in the mechanism of abrasive wear of ferrite-cementite structures. 2. With a carbide content of 0-50% wear occurs by microcutting of the ferrite matrix. The carbides removed from the surface are removed with the microchip while not having a significant influence on wear resistance. 3. With a carbide content of 50-75% wear occurs as the result of multiple crumpling of the ferrite matrix all the way to cracking of the carbides or formation in the ferrite of fatigue cracks on which surface microvolumes separate from the metal. 4. With a carbide content of more than 75% the ferrite matrix ceases to be plastic and wear occurs as the result of abrasion of the whole mass of carbides entering onto the surface. In this case the wear resistance increases by two orders of magnitide.
