HVOF coat screw - Shreeji Corporation

HVOF coating is mostly used to deposit wear and corrosion-resistant coatings on materials like ceramic and metallic layers. Molten or semi-molten materials are sprayed onto the surface by means of the high temperature and high-velocity gas steam so that it produces a dense spray coating that can be of a high surface finish.HVOF Coated Screws provide reduced costs, improved performances, and improved electrical properties. The HVOF Coating process also enables components to operate both in higher and lower temperatures within harsh chemical environments. The HVOF Coated Screws also improve the efficiency and the life of other mating components.Using HVOF Coating technology, alloy powder spraying under high pressure & velocity. The adhesive force is 10,000 psi & the powder density can achieve 99.8% which offers outstanding performance in wear & corrosion resistance.The material that is used in a bimetallic screw is Tungsten Carbide Alloy to achieve the surface hardness of 60-65 HRC. The available diameter sizes are 14mm to 200mm and the available length can go upto 6 meters long. The process method using which a bimetallic screw is made is the HVOF Spray method. It is a speciality for halogen free material with glass-filled content below 65%.
