【 摘 要 】

A paper presents a piece of information about innovate surfacing technology with micro-jet cooling. There are put down information about parameters of shaft surfacing with micro-jet cooling process. There were given information about influence of various micro-jet gases on metallographic structure of machine shaft after surfacing. There were analyzed tribological properties of welds. Welding surfacing process is very often used to apply a hardness or wear-resistant layer of base metal. It is very important method of extending the life of machines, tools, and construction equipment. Surfacing is also known as wearfacing, is often used to build up shafts, gears or cutting edges. Regenerated surface properties of various machine elements do not provide good tribological properties. The tribological interactions of a solid shaft surfaces were tested after welding with micro-jet cooling.
