WHAT IS THERMIONIC EMISSIONS?

Heating a conductor to a temperature sufficiently high causing the conductor to give off electrons is called THERMIONIC EMISSION

200

Current that flows in pulses in the same direction is called....

Pulsating dc

300

What is the advantage of directly heated cathodes

They reach operating temperatures quickly

400

What are the purposes of the transformer in a power supply

It couples the power supply to the ac line voltage, isolates the ac line voltage from the load, and steps this voltage up or down to the desired level.

500

What are the four basic sections to a power supply

 Transformer, rectifier, filter, regulator

400

what are the rules for aircraft confined space 

 Is large enough and configured such that an employee can bodily enter and perform work Has limited openings for entry and exit

500

what are some examples of aircraft confined space?

 4 minimum

CORROSION

100

WHAT IS CORROSION?

degradation of metals, usually through oxidation, causing, for example, the rusting of iron, tarnishing of silver, or loss of structural material

200

WHAT ARE THE CORROSION PUBS?

01-1A-509 SERIES

300

What is the difference between anode and cathode?

 Oxidation occurs at the anode (loss of electrons, metal loss), while reduction occurs at the cathode (gain of electrons)

400

WHAT ARE THE KEY FACTORS THAT CAUSE CORROSION?

ENVIRONMENTAL, TEMPERATURE, AND OXYGEN

500

WHAT ARE 5 TYPES OF CORROSION

(100 PTS FOR EACH)

• Uniform Corrosion: Even metal loss over a large surface area.
• Galvanic Corrosion: Occurs when two dissimilar metals are connected in an electrolyte; the more active metal (anode) corrodes.
• Pitting Corrosion: Localized, intense destruction creating small holes.
• Crevice Corrosion: Occurs in confined spaces (under gaskets, bolts).
• Stress Corrosion Cracking (SCC): Cracking caused by the combination of tensile stress and a corrosive environment.
