A study of temperature effects on car coated substrate in laser paint removal
Cynosure Cynergy Pulse Nd:YAG laser was used to remove the painted material of 54 car coated substrate samples A, B and C by manipulating the laser fluence energy (F), pulse width (PW), repetition rate (RR) and beam size (BS). Alicona IFM G4 was used to analyze irradiated crater depths and obta...

| Summary: | Cynosure Cynergy Pulse Nd:YAG laser was used to
remove the painted material of 54 car coated substrate samples
A, B and C by manipulating the laser fluence energy (F), pulse
width (PW), repetition rate (RR) and beam size (BS). Alicona
IFM G4 was used to analyze irradiated crater depths and
obtained the optical surface micrograph which provides a
pattern of graphical illustration of the removal process. Average
temperature (ΔTAV) of car metal substrate was determined
during the laser paint removal process by using TC 6621
thermocouple. The maximum ΔTAV (
0C) reached were 30.36 and
34.89 with BS 3 mm and 5 mm for sample A, 30.25 and 32.6 with
BS 3 mm and 5 mm for sample B whereas 28.16 and 33.15 with
BS 3 mm and 5 mm for sample C. |
