Etymology: The sense "removed by heat" is the more surprising part: the word began as a plain Latin verb meaning "carried away," and only in the 20th century did it narrow to describe surfaces that vanish when heated, as in spacecraft heat shields. Its ancestor is Latin "ablatus," the past participle of "auferre," "to carry away," built from "ab-" ("away") and "latus," the past participle of "ferre," "to carry." English first borrowed the Latin participle in the Middle English "ablat," meaning "taken away," and the verb "ablate" appeared in the 1500s, only to fade out by the early 1600s. Its modern revival was a back-formation from "ablation," a term for the removal of material, which is why the verb was reinvented rather than inherited. The past participle "ablated" is the form used here, and it is the one that carries the heat-related sense. The adjective therefore keeps the old idea of removal while narrowing it to material lost through extreme temperature.
