Definitions

  • a hearth roll having a metal surface coated with a wear resistant refractory oxide coating which comprises particles of zirconium silicate and/or its decomposition products SiO2 and ZrO2, in a mixture with particles of zirconia fully or partialy stabilized with an oxide selected from Ca0, Y203, Mg0, Ce02 and Hf02.
  • a process for forming a wear resistant and thermal shock resistant refractory oxide coating on a metal hearth roll for use in the continuous annealing of steel comprises: formulating a powder feed composition comprising mixing powder particles of zirconium silicate with powder particles of zirconia at least partially stabilized with an oxide selected from Ca0, Y203, Mg0, Ce02 and Hf02; and thermally spraying the powder feed composition on the metal roll to form an as-deposited coating composition which, by x-ray phase analysis, comprises: Zr02 ⁇ x where x is one of the stabilizing oxides; ZrSi04 and/or its decomposition products SiO2 and ZrO2, and Si02.
  • the powder feed composition should comprise at least 65 wt% stabilized zirconia with the remainder substantially zirconium silicate whereas for detonation gun application the powder feed composition should comprise at least 40 wt% stabilized zirconia and up to 60 wt% zirconium silicate.
  • the zirconia may be either fully or partially stabilized although partially stabilized zirconia is preferred.
  • the impervious layer may be less than 0.005mm (5 microns) and is produced as a result of interdiffusion or oxidation in an environment at an elevated temperature in the presence of oxygen.
  • a similar layer may form in an inert atmosphere as a result of reaction between the oxide overcoat and the metallic undercoat.
  • the sample substrate material had a thick plate shape with a dimension of 50x50x10 mm, one 50x50 side coated.
  • the sample substrate was 304 stainless steel.
  • Thermal shock resistance is evaluated by counting how many cycles the coating can survive without spalling off. Sample No. of Cycles 8 no spalling after 20 cycles 13 no spalling after 20 cycles 14 spalling after 6 cycles
