Environmentally friendly lubricants with boric acid effectively reduce friction and wear during titanium sheet metal forming. These advanced lubricants improve the forming process, minimizing tool damage and enhancing product quality.
Area of Science:
- Materials Science
- Tribology
- Manufacturing Engineering
Background:
- Friction and wear are significant challenges in metal forming, especially with titanium alloys.
- Titanium buildup on tools leads to increased wear and forming defects.
- Effective lubrication is crucial for mitigating these issues and reducing tool damage.
Purpose of the Study:
- To investigate the tribological properties of environmentally friendly lubricants containing boric acid for titanium sheet forming.
- To evaluate the effectiveness of these lubricants in reducing friction, wear, and galling.
- To assess the impact of boric acid-enhanced lubricants on the quality of formed titanium parts.
Main Methods:
- Technological tests including strip drawing, Erichsen cupping, and spherical part formation.
- Industrial-scale forming trials.
- Numerical simulations using the finite element method (FEM) with PamStamp 2G software.
- Analysis of lubricant performance based on experimental and simulation data.
Main Results:
- Lubricants with boric acid demonstrated a positive effect on titanium sheet forming.
- Reduced friction and wear were observed, leading to less titanium buildup on tools.
- Both experimental tests and numerical simulations confirmed the benefits of boric acid additives.
- Improved quality of formed titanium parts was achieved.
Conclusions:
- Environmentally friendly lubricants with boric acid are effective in improving the tribological conditions during titanium forming.
- The addition of boric acid enhances lubricant performance, reducing tool wear and preventing galling.
- This approach offers a viable solution for more efficient and sustainable titanium metal forming processes.
