- Chromium Surface Coating: Improves wettability and bonding between diamond and binder systems.
- Carbide Interface Layer Formation: Forms a chromium carbide layer during sintering for superior grip strength and interfacial hardness.
- Diffusion Barrier Protection: Blocks Fe/Co/Ni diffusion from the bond into diamond, reducing catalytic graphitisation at elevated temperatures.
- High-Temperature Stability: Maintains diamond strength and cutting performance under heat generated by sintering and heavy grinding.
- Strong Diamond Retention: Reduces grit pull-out and maintains stable cutting efficiency.
- High Wear Resistance: Enhances tool durability under continuous grinding conditions.
- Good Oxidation Resistance: Protects diamond particles during processing and operation.
- Versatile Bond Compatibility: Suitable for resin, cobalt, and bronze bond systems.
Cr Coated Diamond Powder
20+ Years Experience
Ultra-Precision Quality
Customized Solutions
Cr Coated Diamond Powder is a coated abrasive engineered to deliver strong diamond retention, high wear resistance, and stable grinding performance in precision applications. With a uniform chromium coating on synthetic diamond particles, this grade promotes the formation of a chromium carbide layer during sintering, significantly enhancing diamond-to-bond adhesion and tool durability. It is well suited for resin, cobalt, and bronze bond systems where reliable cutting efficiency and long service life are required.
