Selection note: These recommendations are starting points. Final suitability depends on the bond or matrix composition, processing temperature, coating specification and manufacturing method.
Key Factors for Coated Diamond Selection
Select coated diamond by base grade, particle characteristics, coating function and coating specification.
Base Diamond Grade
Match diamond strength, shape, purity and thermal stability to the application before selecting the coating.
Particle Size & Shape
Particle size and shape affect coating coverage, bond retention, matrix packing and final processing performance.
Coating Material & Function
Match the coating to the bond or matrix and the required function, such as particle retention, wettability or interface control.
Coating Specification & Uniformity
Control coating amount or thickness, coverage, adhesion and batch consistency according to the processing system.

Read GuideFrequently Asked Questions
Common questions about coated diamond types, coating specifications and grade customization.
What is coated diamond powder?
+
Coated diamond powder has a metal, carbide or functional layer applied to the diamond particle surface. Common options include Ni, Cu, Ti, TiC, W and SiC coatings or interlayers.
Why are diamond particles coated?
+
Coatings can improve particle retention, matrix wettability, interfacial bonding or reaction control. The required function depends on the abrasive tool, bond or composite system.
How do I choose the right coating?
+
Selection depends on the application, bond or matrix composition, processing temperature, manufacturing method and required interface function. These details should be confirmed before selecting the coating.
How is the coating specification defined?
+
Metal coatings are commonly specified by weight gain, while thin coatings or interlayers may be described by thickness. Coverage, adhesion and uniformity should also be considered.
Can the base diamond and coating be customized?
+
Base diamond grade, particle size, shape, coating material and coating specification can be discussed based on technical feasibility. Customized grades require application and process confirmation before production.
