Abstract
The paper presents the reasoning for the usage of pulsating airflow to apply protective coatings by electric arc
metallization in restoring and strengthening worn parts of equipment of various industries operating in conditions of abrasive,
shock-abrasive, and gas-abrasive wear. It is shown that the key role in ensuring a set of high properties is played by the
formation of a sprayed coating with a fine-grained structure and a minimum amount of oxides.
