Ti Coated Diamond

Titanium-plated diamond powder is mainly used for the manufacture of metal bond diamond tools.
The surface of diamond powder is coated with a layer of titanium , so that the diamond particle will have the great hold force with metal bond, meanwhile prevents heat damage and prolongs the service life.

Brief Introduction

Titanium coated diamond powder is coated with a layer of titanium coating on the surface of diamond particles. So that the diamond particle will have the better bond force with metal matrial in bond.
Meanwhile, In the process of high-temperature sintering and high-temperature grinding, the titanium coating plays a role in isolating diamond thermal damage, reducing thermal shock, preventing diamond carbonization and oxidation, and protecting the hardness of diamond, so that the diamond powder maintains good grinding efficiency and longer service life.

Production Process

Problems and Phenomena:
Metal bond diamond tools such as diamond saw blades and diamond drill bits have been widely used in stone processing, geological prospecting and other industries. 
In the diamond tools made of Fe, Cu, Co, Ni and other binders, the covalently bonded diamond, because the diamond crystal has no chemical affinity with the above-mentioned binder, and the interface is not infiltrated, the diamond particles can only be mechanically embedded in the binder matrix. Under the action of the grinding force, before the diamond grits are ground to expose the largest cross-section, the matrix metal loses the fixation of the diamond particles and falls off by itself, which reduces the service life and processing efficiency of diamond tools. The grinding efficiency of diamond powder is not fully utilized.

1. The bonding strength of titanium and alloy diamond to the matrix is ​​greatly improved
After the diamond is titanium plated on the surface, the surface of the diamond is metalized. In the diamond tool manufacturing process, the plating layer reacts with the abrasive grain interface to form a chemical bond on the one hand, and forms a brazing bond with the bonding agent on the other hand, that is, through the surface plating layer, the diamond abrasive grains achieve chemical and metallurgical bonding with the bonding agent and the matrix. It greatly improves the bonding ability of diamond abrasive particles and bonding agent, and the grinding time of the cutting edge, so that the life of the diamond tool is greatly improved.

2. Titanium and alloy plating on the diamond grit surface improves the thermal stability of diamond abrasive grains
The titanium-coating layer on the diamond grain surface can isolate and protect the diamond abrasive grains from the heat damage during diamond tools manufacturing and use. Due to the existence of the coating, it effectively prevent the diamond crystal shape change and the strength reduction caused by the corrosion of harmful substances on the diamond during high temperature sintering and the graphitization.
