Before applying thermal adhesive to ceramic heat tiles, aerospace technicians must deliberately score the bonding surface. Rather than leaving the material polished and smooth, creating shallow, intentional scratches across the substrate dramatically increases its effective surface area. These microscopic grooves provide mechanical grip for the adhesive compound, preventing the tiles from detaching during high-vibration atmospheric flight. If the surface remains unmarred, the adhesive cannot form an interlocking bond, risking catastrophic failure.
As used in the passage, the word "score" most nearly means which of the following?
- Arecord points or evaluate performance
- make shallow grooves or scratches onAnswer
- Cpolish until smooth and level
- Dcut completely through into separate pieces
Answer
The word "score" in this context means to make shallow grooves or scratches on a surface.
In this technical context, "score" means to make shallow grooves or scratches on a surface. The text explicitly defines the action in the following sentence as "creating shallow, intentional scratches across the substrate" to produce "microscopic grooves" that allow the adhesive to grip.
