Hybrid surface treatment technologies based on the electrospark alloying method

The formation of functional coatings is one of the promising approaches to improving the durability, hardness and wear resistance of machine parts and tools. Electrospark alloying (ESA) has proven to be an effective technology for local surface modification, offering minimal thermal impact, high adhesion and the abilit...

HYBRID SURFACE ENGINEERING OF IMPULSE FACE SEALS FOR NUCLEAR POWER EQUIPMENT

This study investigates the formation of combined wear-resistant coatings on steel rings of face impulse seals (FІS) aimed at improving their operational performance under aggressive environments and radiation exposure. A multistage technology is proposed, including electrospark alloying using a W-Zr-B electrode system...
