| Sumario: | Electrospark alloying (ESA) is a micro-bonding process capable of depositing wearcorrosionresistant coatings to repair, improve, and extend the service life of the components and tools. During coating, short-duration electrical pulses ranging from a few microseconds to a few hundreds of microseconds are used to deposit the electrode (anode) material on the component surface (cathode) to produce a protective layer. One of the main components of installations for ESA is the current pulse source, which is responsible for technological parameters of the metal surface modification process. The data represent novel approaches to the formation of current pulses, which, in our opinion, will essentially expand the process capabilities. |
