Final answer:

The chromium oxide layer is intended to make an instrument more resistant to corrosion.

Step-by-step explanation:

The chromium oxide layer is intended to make an instrument more resistant to corrosion.

Anodizing aluminum strengthens the aluminum oxide layer, which enhances its resistance to corrosion. Similarly, stainless steel, an alloy of iron and chromium, forms a passivating oxide layer that protects against corrosion.

By forming a protective layer, the chromium oxide prevents the instrument from corroding when exposed to oxygen and water, thereby making it more resistant to corrosion.
