Advantages of HVOF powder cemented iron (WC6Co and WC12Co)

HVOF powder cemented iron (WC6Co and WC12Co): Advantages of high performance layer material technology and commercial use

Due to the rapid development of industrial technology, surface engineering technology currently offers material performance, long-term equipment life span, and other important effects. High Velocity Oxygen Fuel (HVOF, High Velocity Oxygen Fuel) production includes a variety of highly effective pressure control methods, which are used to protect the material surface of each process. Cemented iron (WC) series powder, which is WC6Co and WC12Co, has extraordinary hardness, abrasion resistance and anti-corrosion properties, and is an important layer material in HVOF production.

UrbanMines Tech. Limited produces HVOF powder cemented iron (WC6Co and WC12Co) products as a Chinese headquartered enterprise, and has a long history of developing the product technology and providing Japanese quality. UrbanMines’ research department organizes the general HVOF technology, its principles, technology, performance and market demand, etc., detailed analysis of the performance characteristics of WC6Co and WC12Co powder and its application areas.

四、HVOF technology and cementing powder principle

HVOF spray principle

HVOF heating technology uses a variety of high-temperature, high-velocity fuel air flow jetting powder material surface heating technology. During the heating process, the air is mixed with the fuel and the air is ignited, the generative high-temperature air current is used to eject the powder particles, the powder particles are accelerated and heated, and after reaching the appropriate temperature, the beak passes through the substrate surface at high speed, forming a dense layer. The ratio of the heating technology to the heating, the HVOF's heating ability provides higher heating temperature, and the combined force of the base material is strengthened, and the surface of the insulation layer is smoother.

Combination of cemented iron (WC) and iron alloy

Cemented iron (WC) powder has ultra-high hardness and abrasion resistance, and can be used for various types of hardness. In addition, WC6Co and WC12Co powder, Co production combined metal, compacted powder synergy, forming tool have excellent abrasion resistance, corrosion resistance and good processability. Addition of powder does not increase the viscosity of the clay particles, it improves the plasticity of the layer, and it has a slightly inferior technique and improves the combination performance.

五、Technology: HVOF WC6Co and WC12Co powder

During the actual production process, the main components of HVOF pumping technology are as follows:

4.Powder selection : WC6Co and WC12Co powder selection is important. 6% capsule containing WC6Co, and 12% capsule containing WC12Co. Although different powder contents can be used, different types of powders have different properties, WC6Co can be deflected to meet the demand for higher hardness, and WC12Co can also be used under harsher environments, providing even higher hardness resistance.

5.Powder injection : Powder passes through HVOF equipment to accelerate the injection onto the construction surface. During this process, the powder particles accelerate close to the speed of sound, and as they move under high temperature, the final solidification layer forms a dense layer.

6.Consolidation and subsequent force theory : The convergence demand progresses and the condensation process increases, resulting in the combined force of high convergence levels. Usually, the coating layer surface is subjected to thermal processing, mechanical bombardment or other surface processing, and the durability and external quality of the coating layer are high.

六、Excellent performance of clay layer

1. Extremely high hardness and abrasion resistance

The main body of the cassetted iron has extremely high hardness, and it has excellent abrasion resistance, which can be used even under harsh abrasive conditions. No need to worry about high-speed cutting, friction polishing, jade stone machining, etc., which can effectively protect the base material from physical polishing, and provide extended service life.

2. Good anti-corrosive properties

The clay layer has excellent chemical corrosion resistance, has the ability to accept acid, and is resistant to corrosion in poor environments. WC6Co and WC12Co layers, specially designed for chemical engineering, petroleum natural gas development, etc., have the ability to provide high anti-corrosion performance, and reduce the complexity of the construction.

3. Excellent high temperature performance

HVOF's WC6Co and WC12Co layers have good high temperature properties. The high melting point of compacted iron can be used for long-term retention under high temperature environments, suitable for working under high temperature friction environments, as well as oil exploration tools, thermal processing equipment, etc.

4. Good integration force imparting properties

Besides, the phase ratio of other hard materials, WC6Co and WC12Co layers has a favorable combination force and strength, the ability has effective resistance and vibration, and the effect of decreasing the thickness of the layer. The addition of the rod has improved the workability and spreadability of the layer, and the special feature is that it has an additional rod shape and is better at using the middle tool.

4. Area for market demand and demand

As each industry continues to develop its flexible and flexible demands, WC6Co and WC12Co will be able to meet market demands for a long time. Its main areas of use include:

6.Jade industry and metallurgy industry : Jade stone breaking, refracting, etc. are provided, WC6Co and WC12Co have the ability to provide excellent wear resistance, effective long service life, and low wear performance.

7.Petroleum and natural gas operations : Koi tools, pump bodies, gates, etc., constantly exposed to high temperatures and corrosive environments, HVO It is suggested by the authors that F.C. has the ability to make a special combination of anti-corrosion and anti-abrasive ability, and to ensure long-term operation.

8.Aerospace industry : High temperature, high speed, high polishing work environment requirements, materials with high hardness and anti-shock ability, WC6Co and WC12Co coatings, aircraft blades and other parts have been obtained for flight.

9.Mechanical processing and automobile industry : machine processing industry, cutting tools and processing equipment always encounters intense friction and abrasion, WC6Co and WC12Co, written by Ningyuan Nengyeng, suggest tool durability, reduction due to machining guidance, growth improvement, and high production efficiency.

10.Chemical industry : In the chemical industry, in the preparation of reactors, pipes, gates, etc., the ability of the cement to be molded has the effect of resisting corrosion, and the long-term use of the equipment.

5. Summary: Technology driving industry, demand driving movement and innovation
