Agglomerated-sintered or sintered-crushed gray/black particles. Agglomerated-sintered particles are spherical or nearly spherical with good fluidity, while sintered-crushed particles have an irregular shape.
Maximum operating temperature: 500℃.
Key properties: High hardness, dense coating, resistance to abrasive wear, fretting wear, adhesive wear, and erosion wear, and high fracture toughness.
