Analysis of Wear Resistance Characteristics of Additive Products Made from Electroerosive Cobalt-Chromium Powders

Purpose of research of this research is to study wear resistance characteristics of additive products made from electroerosive cobalt-chromium powders.

Methods. Wastes of cobalt-chromium "CELLIT" alloy were used for the research [27]. Butyl alcohol was used as a working  fluid.  A unit  for  layer-by-layer  application  of powder  materials  with plasma  was used for  experimental samples  production.  The  intensity  and  wear  rate  of  the  sample  surface  and  counterface  were  measured  on Tribometer automated friction machine, CSM Instruments. The sample was mounted in a holder. A rod was fixed perpendicular to the surface of a sample. A 6 mm diameter ball made of Stainless Steel AISI 420 (Vickers hardness 5000-8000 HV) was at the end of the rod. Radius of wear curvature was selected by adjusting the displacement sensor. Another sensor compensated the friction force and allowed to set the friction coefficient value at a certain time. The condition of friction surfaces was studied with the help of optical inverted microscope Olympus GX 51 equipped with "SIMAGIS Photolab" automated image analysis system and Quanta 200 3D electron ion scanning microscope.

Results. According to the performed analysis of wear resistance characteristics of additive products made from electroerosive cobalt-chromium powders friction coefficient varies from 0.144 to 0.602. An average friction coefficient is 0.526. A wear factor of the sample is two times higher than the wear factor of counterface.

Conclusion. Performed research allows expanding the information about properties of additive products made from electroerosive cobalt-chromium powders and reducing production cost.
