What are the pros and cons of the repair function of thermal spray?

       Advantages:



Thermal spraying technology is to use a certain heat source, such as arc, plasma arc, combustion flame, etc., to heat powder or filamentary metal and non-metallic coating materials to a molten or semi-molten state, and then rely on the power of the flame itself or external High-speed airflow is atomized and sprayed onto the surface of the pretreated base material at a certain speed, and combined with the base material to form a surface covering coating with various functions.



Wuxi Kete can carry out various thermal spraying processes such as supersonic spraying, plasma spraying, flame spraying (wire spraying or powder spraying), arc spraying, etc. coating, insulation coating, high temperature corrosion resistant coating and thermal barrier coating, dimensional correction coating, etc.



2. Scope of application



Machinable parts: various casing parts, sprayed with thermal barrier coating, wear-resistant coating, etc.; grate parts, sprayed with wear-resistant alumina coating, etc.; sealing parts, sprayed with wearable coatings such as nickel graphite, nickel Covered with diatomite, etc.; shaft and disc parts, sprayed with wear-resistant coatings of cobalt-tungsten carbide, cobalt-molybdenum-chromium-silicon, etc.; blades, sprayed with anti-fretting wear coatings, copper-nickel-indium, and anti-adhesion dry film lubricants layer; flame barrel, sprayed thermal barrier coating and abrasion resistant coating.



Various types of out-of-tolerance parts due to improper machining or other reasons can be sprayed and corrected to avoid parts being scrapped and lost.





Defect: Thermal spray technology is suitable for large wear correction. However, thermal spraying cannot be corrected on site, the correction process is complicated, and the correction period is long and the correction cost is high.
