WC-10Co4Cr Thermal Spray Poda

  • Poda ya Agglomerated & Sintered na Sintered na Kusagwa zinapatikana. Poda zilizounganishwa na zilizotiwa sintered ni duara au karibu-spherical na zinatiririka vizuri. Poda za sintered na kusagwa ni za kawaida.
  • Kiwango cha juu cha joto cha huduma ni hadi 500 ℃.
  • Mipako mnene ina ugumu wa hali ya juu na ukinzani bora dhidi ya uvaaji wa abrasive, uvaaji wa fretting, kuvaa wambiso, na kuvaa kwa mmomonyoko.
  • Replacing hard chrome plating.
  • Cobalt &Chrome has better corrosion resistance and wear properties than Cobalt, especially in wetting and corrosion environments.
  • Mainly used in aircraft landing gear, gate valves, ball valves, paper rollers, hydraulic cylinders, compressor rods, metallurgical rollers, mechanical parts, etc.
