The Tribotechnical Properties of Electrosparks with a Secondary Bronze Coating

The high cost of metal powder materials and the energy consumption methods involved in their production have led to an increase technologies for restoration hardening parts. One method solving this problem is recycling powders. A promising processing waste from machine-building industries, including those utilizing non-ferrous metals alloys, electroerosive dispersion. Metallic powders secondary raw obtained manner good physical mechanical properties, two three times less than industrial ones. However, tribotechnical properties use parts are still poorly understood. This paper presents a comparative analysis coatings via electric spark treatment with electrodes composed bronze CuAl9Fe3 (CuAl8Fe3) (in state delivery), sintered dispersion followed by plasma sintering. results tests under conditions dry friction showed that complex indicator wear resistance—the factor (F)—under conditions, mates after electrospark coating bronze, was 1.94 coating. confirmed effectiveness using cheap repair restoring strengthening worn machines operating conditions.
