Thermal spraying technology is an important
technology in surface treatment engineering. It plays a role in strengthening
and protecting the surface of workpieces. It has rich spraying materials and
can provide various functions such as surface wear resistance, corrosion
resistance, oxidation resistance, high-temperature wear, heat insulation and
insulation. In addition, it has the characteristics of simple and flexible
operation, especially suitable for on-site construction and workpiece repair.
Thermal spraying technology is not only an effective method for surface
strengthening and pre protection of new equipment, but also an economic and
effective means for on-site construction and local repair of workpieces. Over
the years, it has been widely used in the strengthening and repair of various
general mechanical parts in various industrial fields, such as various shafts,
valves and fans, and has achieved remarkable social and economic benefits. In
the past decade, thermal spraying technology has developed rapidly at an annual
growth rate of 5% - 10%. So far, the global output value of thermal spraying
application has reached 1.35 billion US dollars.

With the continuous progress of thermal
spraying technology, such as the advent of supersonic flame spraying and
supersonic plasma spraying technology, and the continuous development of
various new spraying materials, the weakness of low bonding strength and poor
impact resistance of thermal spraying coatings in the past can be overcome. The
application of new thermal spraying methods has brought a qualitative leap to
the coating quality, and the porosity of the coating can be reduced to 0.5% -
1.0%; The bonding strength of the coating can reach 70mpa-140mpa. With the
continuous progress of industrial production technology, the application range
of thermal spraying technology in various industrial fields will continue to
expand.
