Structure and wear resistance of welded metal 120Cr14Ni6Mn6Mo3Ti2Nb2
The structural-phase composition of the 120Cr14Ni6Mn6Mo3Ti2Nb2 type alloy welded by the arc method has been investigated. Granulometric analysis and calculation of the volume fraction of dispersed hardening phases in the structure of the deposited metal have been performed. The process of wear of the alloy under the influence of a fixed abrasive was studied by the method of sclerometric tests. Using the developed installation for express testing of metals for resistance to gas-abrasive wear, studies of the nature of plastic deformation of the alloy under the influence of high-speed abrasive particles at temperatures elevated to 600 ° C were carried out.
