Boride Powder
Boride-based powders are commonly used in thermal spray applications due to their high hardness, wear resistance, and thermal stability. Some commonly used boride powders for thermal spray include:

1. Boron Carbide (B4C): Boron carbide is one of the hardest materials known, making it ideal for applications requiring high wear resistance. It also has excellent chemical resistance and thermal stability.

2. Titanium Diboride (TiB2): Titanium diboride offers a combination of high hardness, excellent wear resistance, and good thermal conductivity. It is often used in applications where both wear and heat resistance are required.

3. Tungsten Boride (WB): Tungsten boride powders have high hardness, excellent wear resistance, and good thermal stability. They are commonly used in thermal spray applications for their ability to withstand high temperatures and resist wear.

4. Chromium Boride (CrB2): Chromium boride powders offer high hardness, wear resistance, and good thermal stability. They are often used in thermal spray coatings for applications requiring resistance to abrasion and erosion.

These boride-based powders can be used in various thermal spray processes such as plasma spraying, high-velocity oxy-fuel (HVOF) spraying, and detonation gun spraying to provide protective coatings on surfaces that require enhanced wear resistance and thermal protection.
