●High hardness, high toughness ●High wear resistance ●Self-lubricating, no residue ●Strong corrosion resistance ●Low coefficient of thermal expansion ●Good insulation
●By isostatic pressing, firing high-density structural parts, long life, good heat dissipation performance, small friction coefficient, uniform injection ●According to the spray of raw materials, spray amount, view point, anti-blocking condition, etc., the product has hollow push shape, half-solid half-hollow cone, solid cone, etc., the quality is easy to clean. ●The yttrium oxide stabilizer nozzle has excellent corrosion resistance and is suitable for the process of nickel-based alloy and superalloy. Zirconia nozzles with magnesium oxide and cerium oxide as stabilizers have excellent thermal shock resistance. The outside of the synthetic nozzle is alumina, and the inside is zirconia, which can be customized to make the nozzle match with the atomizing equipment;
1. 3Y, 5Y, 8Ymol yttrium stabilized zirconia zirconia powder
2. Open mold processing: dry pressing, CIM injection molding, isostatic pressing.
3. Appearance processing: surface grinding, outer diameter/inner diameter grinding, fine engraving machining, grinding, polishing grinding.
