Overview of WC-12Co Powder
مسحوق WC-12Co, short for Tungsten Carbide-Cobalt powder, is a specialized material often used in coatings, manufacturing, and tools requiring extreme wear resistance, durability, and toughness. Known for its versatility and exceptional mechanical properties, WC-12Co finds significant applications in industries such as aerospace, automotive, oil & gas, and heavy machinery.
Tungsten carbide (WC) mixed with cobalt (Co) creates a robust composite where tungsten carbide imparts hardness, and cobalt enhances ductility. Typically used in thermal spray coatings, WC-12Co powders are essential for surfaces exposed to abrasion, erosion, and high-stress environments.
This article explores everything you need to know about WC-12Co powder, including its composition, properties, applications, models, comparisons, and more. Whether you’re looking for technical specifications, supplier details, or performance insights, this guide has you covered.
تكوين WC-12Co Powder
Understanding the material’s composition is vital as it influences the powder’s mechanical and chemical behavior.
| المكوّن | النسبة المئوية | الغرض |
|---|---|---|
| Tungsten Carbide (WC) | 88% (by weight) | Provides hardness, abrasion resistance |
| الكوبالت (Co) | 12% (by weight) | Adds ductility, toughness, and bonding |
| Trace Elements | <1٪ | Improves powder properties |
Key Insight: The 88:12 WC-Co ratio strikes a balance between hardness and flexibility, making it superior for wear-resistant coatings compared to alternatives like WC-17Co.
Characteristics of WC-12Co Powder
WC-12Co powder stands out for its exceptional properties. Here’s a breakdown of its primary characteristics:
| الممتلكات | التفاصيل |
|---|---|
| الصلابة | Up to 1500 HV (Vickers Hardness) |
| الصلابة | Excellent fracture toughness due to cobalt |
| الكثافة | 14.2 – 14.6 g/cm³ |
| التوصيل الحراري | High thermal stability in extreme conditions |
| مقاومة التآكل | Good but can be enhanced with additives |
