Materials and Processes
Which of the following materials may be inspected using the magnetic particle inspection method?
Iron alloys.
Caustic cleaning products used on aluminum structures have the effect of producing
corrosion.
Drawings may be divided into three classes:
The More you take, the more you leave behind. What am I ?
Foot steps
One way a part may be demagnetized after magnetic particle inspection is by
slowly moving the part out of an AC magnetic field of sufficient strength.
. Fretting corrosion is most likely to occur
when two surfaces fit loosely together and can move relative to one another.
Almost all objects are made up of one or a combination of shapes, which are

Which type crack can be detected by magnetic particle inspection using either circular or longitudinal magnetization?
45°.
The rust or corrosion that occurs with most metals is the result of
a tendency for them to return to their natural state.
How many twist per inch in safety wire?
6-8
Which of the following methods may be suitable to use to detect cracks open to the surface in aluminum forgings and castings?
Dye Penetrant
Ultra Sonic
Eddy Current
Metallic Ring
Dye penetrant inspection and eddy current inspection.
What are the desired effects of using Alodine on aluminum alloy?
A slightly rough surface and increased corrosion resistance
What is the 3RD planet from the sun?
Earth
To detect a minute crack using dye penetrant inspection usually requires
a longer-than-normal penetrating time.
Intergranular corrosion in aluminum alloy parts
cannot always be detected by surface indications. Intergranular corrosion forms along the grain boundaries within an aluminum alloy
. Finished marks are used for this purpose:
What is more useful when it is broken?
