How to choose a suitable titanium alloy mirror polishing process?
Guidelines for Selecting Mirror Polishing Processes for Titanium Alloys
1. Mechanical polishing
Applicable scenarios: In situations where extremely high surface roughness is required, it is necessary to achieve a super smooth surface with Ra ≤ 0.01 μ m.
Advantage: The mirror effect can be achieved through ultra precision polishing technology, which is the highest precision among traditional polishing methods.
Limitations: It requires phased operation, with complex and time-consuming processes.
2. Chemical mechanical polishing
Applicable scenarios: High end fields such as medical and healthcare implants that are sensitive to surface defects require a balance between low roughness and high efficiency.
Advantages: Combining chemical dissolution and mechanical grinding, it can handle complex shaped workpieces and can be operated in batches.
Limitations: Precise control of polishing solution composition is required, and the technical threshold is high.
3. Laser polishing
Applicable scenarios: aerospace, medical and health equipment and other fields that require rapid processing and avoid thermal deformation, can reduce surface roughness by about 87%.
Advantages: Non contact processing, suitable for precision components, friction coefficient can be reduced by 16%.
Limitations: High equipment costs require parameter optimization.
4. Suggestions for selection
Priority mechanical polishing: Especially suitable for mold manufacturing if pursuing the ultimate mirror effect and with sufficient budget.
Consider CMP: When balancing efficiency and accuracy, such as in the healthcare or semiconductor industries.
Attempt laser polishing: for heat sensitive or complex structural components, but equipment investment needs to be evaluated.
