4.1.3.3. Conclusion
The observed results with the different cooling installations are similar as the ones obtained with the
trials where sand blasting was used instead of conventional grinding (Task 5.3: Grinding optimization
to define the best starting roughness). By changing the cooling an impact could be seen on the
oxidation mechanism but no additional influence was observed. Also the roughness was similar in both
campaigns (±1.5-1.6μRa)
