RESTORATION AND ENHANCEMENT OF EMPLOYMENT BODIES OF THE EMERGENCY-TAKING INSTRUMENT
Journal Title: Проблеми тертя та зношування - Year 2017, Vol 76, Issue
Abstract
To accomplish the task of saving people and material values, the rescuers of the DSNU use a variety of equipment and special tools, the reliability of which depends not only on the lives of victims, but also on the rescuers themselves. Today, fire and rescue units in Ukraine often use machinery and equipment that has expired or service life and parts and whose working bodies are partially worn out. The use of protective coatings based on eutectic alloys Fe-Mn-C-B-Si doped Cr can improve the wear resistance of fire and emergency rescue equipment. The application of these materials by the method of surfacing GMA (MAG) allows you to recover partly worn or damaged working elements and parts, which is more cost-effective than replacing these parts with new ones. The surfaced protective coating has a high adhesion with the substrate material. No layers and significant defects have been detected in the deposited layer. Restoration of worn working tools of the emergency rescue tool with eutectic coating on the basis of Fe-Mn-C-B-Si doped Cr system allowed to increase their wear resistance ~ 1,8 times.
