Products Description
Compared with general-purpose molybdenum wires, thermally sprayed molybdenum wires emphasize no welded joints, strict wire diameter tolerances, can carry out eddy current flaw detection, and the whole coil weight can reach 20-25 kg. These characteristics are directly related to the continuity and finality of the coating, making it the preferred material for surface strengthening of key parts such as automotive rings and synchronous rings. Whether it is the manufacture of new parts or the restoration of old parts, thermally sprayed molybdenum wire can provide a cost-effective wear-resistant protection solution.
High melting point
The advantages of thermally sprayed molybdenum wires come from the physical and chemical properties of molybdenum metal itself. Its melting point is as high as about 2623 °C, and the coating can still be structurally stable at high temperatures; The density is about 10.2 g/cm ³, achieving a good balance between weight and strength; Low thermal coefficient, matching most metal substrates, reducing the risk of cracking or spalling due to effective thermal cycling.
Low thermal conductivity
The coating has high hardness and a low coefficient of friction after formation, and shows a good tendency of self-lubrication, especially under sliding conditions; the molybdenum oxide film formed at high temperature further resists sticking and scratching. At the same time, molybdenum has corrosion resistance to a variety of non-oxidizing media, and its thermal conductivity helps rapid dispersion and avoids local overheating.
Excellent adhesion
The purity of high-quality thermally sprayed molybdenum wires is usually ≥ 99. 95%, and the tensile strength is moderate (usually in the range of 700-900 N/mm ²), ensuring smooth wire feeding, fine and uniform droplets, and a final coating with low porosity and high bond strength.
auto industry
In the automotive industry, parts such as rings, synchronizer rings, shift forks, and synchronizer bodies are subject to high-load sliding and impact. The molybdenum coating formed by thermal spraying molybdenum wire can significantly improve the wear resistance and anti-bite performance, prolong the life of parts, and improve the sliding efficiency.
Mechanical Repair
The field of mechanical maintenance also relies on thermally sprayed molybdenum wires. After wear of bearing shell and shaft parts, flame spraying or arc spraying is used to restore the size, and at the same time, the surface performance is better than that of the original substrate, which is a cost-effective repair plan.
High temperature field
In terms of high-temperature areas such as turbine blades and combustion chamber-related components, molybdenum coatings provide additional thermal protection and wear protection.
