🔍 Key Concepts

• Static gear tooth contact checks and what they are used for • Typical machinist/layout compounds used to show contact patterns on metal surfaces • Difference between surface treatment chemicals and marking/spotting compounds

💭 Think About

• Ask yourself: for a static tooth contact pattern, do you need something that etches/chemically reacts with the metal, or something that simply marks where two surfaces touch? • Which option is commonly used in precision fitting of bearings and gears to visually show high spots and contact areas? • Consider which materials are designed for temporary, easily visible marking versus permanent coloring or surface alteration.

✅ Before You Answer

• Verify which substance is known as a spotting/mating compound in machine work for checking contact patterns. • Check which of the choices is used for chemical etching or metal prep, which would NOT be appropriate for a simple static tooth contact test. • Eliminate any choice that would leave a permanent or hard‑to-remove mark rather than a light, transferable film showing contact.
