Research of wearproofness of the details restored by high temperature brazing

Abstract

Research of wear resistance of details was carried out by different methods of restoring in laboratory condi-
tions.Laboratory researches of comparative wear resistance in the conditions of a sliding friction were carried out on samples

with the increased layer from the researching materials.For comparison of their wearproofness as a standard was chosen the steel
45 tempered CHF (current of high frequency). To define the most wearproof method of restoration is a researching objective.
Besides, the wear resistance of the surface restored by soldering was estimated by comparison with the layer of a wire which
is built up under gumboil steel wire. At test for wearproofness of the researching materials the choice of a type of wear has
been defined that in use car details usually work in the conditions of grease.Tests were carried out by special car of friction, and
results of wear were registered.As have shown results most intensively wear the samples, which are built up under gumboil, and
the smallest wear has the samples increased by soldering ofspecial solder, results has shown better than a standard steel 45. In
conclusion, we can note, on the basis of results of laboratory researches the best result has shown the new sample increased by
a special wire with the subsequent soldering.
