,Cause of Blistering on coatings? - ANSWER: Oil, moisture and / or grease
Saturation point drops as? - ANSWER: Air is compressed, making air wetter
Check compressor for water contamination at? - ANSWER: Moisture traps, inter
cooler and aftercooler
Common Hot Dipped (HD) inspection defects - ANSWER: Cracking, peeling, bare
spots, lumps, Blisters, flux inclusions, ash inclusions and dross inclusions
Describe what a Tooke Gage is and some models - ANSWER: *Destructive test
instrument
*Used on non-magnetic or nonferrous
Substrate
*has illuminated 50x microscope
*good from 0-100 mils
*Groove cut through coating
*Models are Mark II and Mark III
Centrifugal blast machine showing low amperage could indicate? - ANSWER:
*Abrasive starved wheel or
*Flooded or choked wheel
How to rectify water contamination: - ANSWER: *ensure cooling water is turned on
*Ensure drains are not plugged
*last resort is to consider installing larger or
Additional moisture traps
Air oxidization enters the coating when? - ANSWER: After solvent evaporates
What is the curing method for alkyds and epoxy ester? - ANSWER: Air drying
What is the NACE / SSPC standard for Surface Prep by Chemical or thermal means for
concrete? - ANSWER: NACE 6 / SSPC-SP13
What are impressed current power sources - ANSWER: *Rectified Commercial Power
*Solar Cells
*Generators
*Fuel cells
*Wind Powered Cells
*Thermo electric
What is the purpose of dehumidification? - ANSWER: remove moisture to lower dew
point
Electronic hygrometers check - ANSWER: *Relative humidity
, *Air temperature
*Dew Point temperature
How do you reduce the relative humidity of the boundary layer? - ANSWER:
*Increase surface temperature
*Reduce moisture by dehumidification
Equipment used for dehumidification? - ANSWER: *Refrigeration
*Desiccant
Describe passivation and what it does? - ANSWER: *formation of protective oxide
film
* reduces chemical activity
*reduce the ability to corrode
What are the effects of oxygen on corrosion? - ANSWER: Oxygen increases corrosion
What are the effects of temperature on corrosion? - ANSWER: Higer temperature
increases corrosion
What are the effects of chemical salts on corrosion? - ANSWER: They increase the
electrolyte efficiency, therefore increasing corrosion
What are the effects of Humidity on corrosion? - ANSWER: A wetter environment
means more corrosion is likely to occur
What are the effects of Pollutants and Acid gases on corrosion? - ANSWER: Acid rain,
chemical byproducts and chlorides all promote corrosion.
What are the causes for pinholes? - ANSWER: *Coating overspray
*solvent entrapment
*porosity in previously applied coat
*incorrect spray viscosity
*coating on hot surface
What are the limitations of Magnetic Gages? - ANSWER: *only work on magnetic
surfaces
*Sensitive to discontinuities in the steel, like
holes, corners and edges
*Affected by nearby magnetic fields like power
lines, welding equipment or other masses of
steel.
*roughness of steel may distort the readings
What type of High Voltage (HV) detector is used for concrete? - ANSWER: Constant
current DC
