Type: article
Abstract: Characteristics of wear resistance of electrospark coatings deposited using the electrode material made of electroerosion powders of high-speed steel are analyzed. Electrodes for electrospark alloying are fabricated by hot compaction (with the passage of a high- amperage current in vacuum at 950 °C for 3 min) of the powder fabricated by electroerosion dispersing of waste of high-speed steel R6M5. Electrospark coatings with the application of these electrodes were formed on the samples made of steel 30KhGSA using an UR-121 installation. The friction coefficient and wear rate of the sample surface and counterbody were measured using a computer- aided automated friction machine «Tribometer» (CSM Instrument, Switzerland) according to the standard «ball–drive» testing layout.
