Cr Coated Diamond Powder

20+ Years Experience Consistent Batch Quality Customized Solutions

Product Overview

Cr Coated Diamond Powder is a chromium-coated synthetic diamond developed for selected metal-bond abrasive tools and thermal composites requiring improved diamond–metal interface control. Under suitable thermal processing, chromium can react with diamond to form chromium carbide phases, strengthening interfacial bonding and improving compatibility with copper and other selected metal matrices.

Features

Chromium Surface Coating: Provides an active metal layer for interface modification in selected metal-based systems.
Carbide-Forming Interface: Chromium can form chromium carbide phases at the diamond surface during thermal processing.
Improved Metal-Matrix Bonding: Supports stronger interaction between diamond and selected metal matrices.
Improved Grit Retention: Can enhance diamond retention in selected sintered metal-bond abrasive systems.
Thermal Composite Compatibility: Suitable for Cu–diamond systems where interface bonding and thermal transport require modification.
Controlled Interface Design: Coating thickness and subsequent heat treatment can be selected according to the matrix and process.
