Ablation

Ablation refers to the process of removing or destroying material from a surface, often through focused energy like heat, laser, or chemical reactions. In medical contexts, it involves eliminating tissue, such as tumors or abnormal cells, to treat conditions. In engineering or aerospace, ablation is used to cool surfaces by eroding material away during high-stress situations, like re-entry into Earth's atmosphere. The goal of ablation is to eliminate or modify specific parts of an object or tissue, either to improve performance, safety, or health outcomes.
