Carbide alloy is the “tooh of industrial”, and nano WC-Co is widely used in machining cutting tools, oil and geological exploration and mining tools, precision molds and anti-wear products due to its high strength, hardness, abrasion resistance and oxidation resistance.
Application of WC-Co Nano composite Powder is based on Its Technological Characteristics.
The nano WC-Co powder is prepared by ultra-fine alloy than the traditional mixture. The WC phase of the prepared alloy is finer and more homogeneous, with better physical and mechanical properties and longer service life.
WC-Co is a very good bit material, smicro-drill bit made by sintering nano WC-Co applied for processing of printed circuit board has the lifetime 3-4 times of common carbide drill, and 50 times of stainless steel drill.
WC-Co nano composite powder can be used for anti-wear coating.
WC-Co composite powder is based on WC particles as the core, with cobalt as coating, cobalt content can be changed in the range of 8% -22%, the higher the cobalt content, spray coating strength and toughness on The higher the crack susceptibility is reduced, but the abrasion resistance also decreases. WC-Co has a high hardness and wear resistance, is the most important hard wear-resistant composite powder material. Nano WC-Co material particle size is too small, difficult to flow, easy to plug the spray barrel, and because of its surface activity, spraying process is easy to sintering, so WC-Co nano-powder used for spraying, the need to directly made it directly Thermal sprayed nano structured powders, this process also known as granulation. The nano-WC-Co powder is agglomerated into 15-50um micron-grade powder, which can be used directly for thermal spraying.
If you want use the nano-WC-Co directly thermal spray, reasonable process and a special material form is required, and select the supersonic flame spray plasma spraying is better.
With the increasingly mature powder technology, composite powder will be with
There is a broader application prospects, not only in the field of tool materials more
Large development, and will be in the field of thermal spray materials and wear-resistant structural materials and has great development and market room.
