ASVAB Practice Test

This type of pattern on metal is made by a process called?

1. Etching

2. Knurling

3. Stamping

4. Texturing

The correct answer is: Etching

The correct answer is etching. Etching is a process used to create patterns or designs on metal surfaces through the use of acid or other chemicals. By applying an acid-resistant substance to areas of the metal, the exposed parts can be eroded away by the acid, which results in a detailed pattern defined by the areas that remain intact. This method is commonly used in electronics, jewelry, and art to produce intricate designs. Knurling involves creating a pattern of grooves or ridges on a metal surface, typically used to provide a better grip on an object. Stamping refers to shaping or cutting metal through a die or a mold, which also doesn't involve the fine detailing possible with etching. Texturing can involve altering the surface to create a tactile feel or pattern but does not specifically involve the chemical process that etching uses.
