Titanium Anode for Cathodic Protection

Anodizing
Anodizing, as a mature process well known to the public, will not be introduced here. In addition to the commonly used aluminum alloy anode, titanium metal can also be used as an anode, and most of the titanium coloring process is achieved through anodic oxidation, which can make more rich colors and patterns, highly differentiated, including ice crystal, thread and other options.

PVD coating
PVD is also a kind of physical vapor deposition, vacuum coating, and the process has been very mature. It is possible to do PVD on the surface of titanium alloy, mainly to increase the functional coating and play a role in protection and protection. However, it is worth noting that at present, PVD can only be functional to barely pass, and the durability needs to be improved, unless the performance of the PVD substrate material is very good.

CNC
CNC machining of titanium alloy mainly plays the role of shaping and finishing. One of the biggest problems in the machining process is the loss of the tool. Because titanium alloy is relatively hard, the processing difficulty is higher than other metals. In the process of processing, the tool is subjected to high temperature, large cutting force, long friction distance, large vibration deformation, and serious tool wear. It is difficult to process titanium alloy with traditional tools, and it is necessary to use special composite coating knives, even diamond knives, and CBN knives to perform better mechanical processing. In the case of smart watches, for example, the average production of 4 watch cases will lose 1 tool, the cost is huge.

Grinding and polishing
Grinding and polishing is almost a necessary step for every material processing, the purpose is to make the product show a more accurate size, a more delicate texture, often need to use small polishing particles or consumables on the surface of the product at each position to be finely polished. At the same time, through a specific process scheme, special effects can also be achieved, such as high gloss mirror, matte scrub and so on.

Drawing
The titanium surface can be brushed to create a matte finish. This titanium wire drawing effect is very high in the consumer electronics industry products, taking into account the delicate touch and visual beauty, and is recognized and favored by more consumers.

Laser carving
There are mainly laser drilling and welding processes.

Sand blasting
The main purpose of the titanium alloy surface sandblasting process is mainly functional. Including improving the surface adhesion of titanium metal, improving the service life (removing surface impurities, etc.) and increasing the surface flatness and beauty of the product. It can also be understood as the effect of serving other surface treatment processes.
