Description
Modern non-production repairs require the introduction of new technologies to
restore the surfaces of worn machine parts to improve their performance, reliability and durability.
Therefore, the study is relevant in order to obtain optimal materials for the choice of electrical
materials and mode parameters in electrospark doping. As a result of the conducted researches the
mathematical model which describes influence of the basic parameters of processing and chemical
composition of electrodes on quality of processing is developed. It is established that when building
up with electrodes from 150X30 alloy, the hardness increases 2.2 times in comparison with the
hardness of the base metal. The bond strength of the extended layer is provided at the level from
350 MPa to 644 MPa. The highest wear resistance is achieved when using electrodes made of high-
carbon, chromium-doped materials.
