The use of boiler anti-wear spraying in the industry

       1. Bearing



Boiler spraying is used in the machinery industry. Due to the complex working conditions, mechanical equipment often suffers from bearing wear and corrosion, which seriously affects the service life of the equipment. Anti-corrosion coating can be prepared on the bearing surface by using the boiler anti-wear spraying technology, which not only does not affect the strength of the bearing, but also plays a better role in protecting the bearing.

Second, the engine

As the core part of the car, the cylinder wall and the piston are constantly rubbed, and the high temperature environment makes the engine wear more seriously. Boiler anti-wear spray technology can effectively reduce wear and prolong engine life. A molten powder of wear-resistant material is sprayed onto the substrate at high velocity to form a dense plasma coating with high bond strength. The coating will not be oxidized at very high temperatures because it works in an inert gas environment.



Three, defense, aerospace



Take supersonic aircraft, for example. Supersonic planes fly at Mach 5. This means that high temperatures of up to 2000-3000°C are generated on the surface of the aircraft, while the surface parts of the fuselage are subject to friction and structural damage caused by the high pressure. Supersonic spraying technology and new high temperature resistant composite materials can effectively prevent high temperature oxidation of coating materials. Generally speaking, the development of anti-wear spraying for boilers has the characteristics of ultra-high temperature processing, high bonding strength, and not easy to oxidize, with high coating deposition rate, high production management efficiency, low energy consumption, relatively low comprehensive utilization rate of spraying time cost, The coating construction quality is good (which is characterized by dense coating, high comprehensive use strength, superior wear resistance and corrosion resistance) and other advantages. The surface information processing of parts suitable for high wear, high temperature and high pressure system working and living environment will become more mature in the future.
