Black titanium gold is a common color electroplating method for color stainless steel, and it is also widely used. Compared with the color of rose gold introduced in the last article, black titanium gold has stronger reflective effect, darker color and clearer decorative style.

The most commonly used iron-based and copper-based binders are used as the matrix, uncoated and titanium-coated diamonds are added respectively, and then the iron-based and copper-based binder matrices and iron-based and copper-based binder diamond segments are obtained by hot pressing sintering at different sintering temperatures. By testing the bending strength of diamond cutter head and observing the micro-morphology of cutter head section, the influence of titanium plating on diamond surface on the clamping force of metal bonded diamond cutter head was studied.

Matters needing attention in the use of black titanium gold:

In the electroplating process, there is often a non-stainless steel interlayer between the base stainless steel mesh and the stainless steel mesh coating, which can not form a continuous crystal structure, resulting in poor bonding defects such as blistering or falling off of the coating. Therefore, the metamorphic layers such as scale, rust and scale must be thoroughly removed. Although the treatment layer and coating can be firmly combined with it, it does not need to be removed by etching, and generally only needs pickling.

In the production process, we should pay attention to avoid the feeling of cleaning the surface, and at the same time, we should pay attention to maintaining the air quality in the production process as much as possible to avoid titanium plating in some places with more dust and dust.
