WC-15NiCr Thermal Spray Poda

  • Agglomerated na Sintered kijivu-nyeusi chembe duara au karibu-spherical na mtiririko mzuri.
  • Kiwango cha juu cha joto cha huduma ni hadi 500 ℃.
  • The density coating has high hardness with excellent resistance to abrasive wear, sliding wear, erosion wear, and cavitation.
  • NiCr has better corrosion resistance than Cobalt, CoCr, and excellent resistance to seawater (Saltwater) corrosion.
  • Mainly used in oil field equipment, ball valves (oxidizing environment), hydraulic gate levers, transportation container hydraulic levers, the petrochemical industry, offshore equipment, parts, etc.
