The forming process of titanium plates is similar to that of other materials. When necessary, coatings and lubricants are applied to the surface of rough materials and performed on certain parts of the mold to reduce friction between parts and tools, reduce scratches, improve product quality, and extend tool life. Especially during hot forming, coatings not only alleviate the severe friction between parts and molds at high temperatures but also protect the surface of parts and avoid and reduce oxidation.
In summary, the purpose of using coatings in titanium plate stamping is:
1. Improve the surface quality of parts;
2. Protect titanium parts from oxidation;
3. Reduce the pressure required for forming;
4. Extend the life of the mold;
5. Control the flow of materials during deformation.
The coating should generally have the following properties:
1. Good anti-corrosion performance, no harmful ingredients, no pollution to the material;
2. Certain adhesion, easy to apply;
3. Sufficient strength, the coating is not easily damaged during use;
4. Good lubrication performance;
5. Easy to remove;
6. No harm to the health of operators;
7. Low cost.
Therefore, titanium alloy plate manufacturers can divide the coatings used for forming into two categories according to different use conditions, namely, coatings for normal temperature forming (cold forming) and coatings for high temperature forming.
