Product introduction and applications:


Tungsten carbide, chromium carbide/nickel powder is WC particles, Cr3C2 as hard phase, Ni particles as binding 

phase, reunited after sintering process produced by thermal spraying powder materials, approximate spherical 

powder form. The HVOF and APS process can be used to prepare anti-corrosion and anti-erosion coatings for water-

bearing environment, such as in the paper industry. The coating under 700 ℃ has good thermal stability.


A very hard and dense coating can be prepared using fine - grade powder. The coating requires no further processing and can be used directly.


Typical applications:


Recommended in dense, smooth coating requirements, and under 700 ℃ has excellent oxidation corrosion resistance, such as:


1. Oil and gas pipeline interface;

2. Rotary shaft, blade and piston rod of the mud pump;

3. Paper roll;

4. Rotary shaft, sealing ring and bearing of the pump;

5. Guide plate conveyor belt;

6. Drain valve and compressor valve.

7. Forging tools;

8. Oil field equipment, petroleum machinery.
